Branch‐and‐price for energy optimization in multi‐hop wireless sensor networks

AbstractWireless sensor networks (WSNs) are widely deployed to support transmissions of the huge data emitted by heterogeneous connected devices. The quality of service (QoS) and energy requirements in WSNs are dramatically increasing and becoming challenging issues. Integrating network coding, in the data transmission process, leads to reduced energy consumption and improved QoS. In this work, we study the problem of energy efficiency in multi‐hop WSNs, namely wireless unsplittable multi‐commodity flow with network coding (wUMCFC). We propose mixed‐integer programming formulations of the wUMCFC problem, and we implement an open source solver wUMCFC based on the branch‐and‐price algorithm. To the best of our knowledge, this work is the first study of the wUMCFC problem by mathematical programming tools. We perform a computational study on realistic instances with an analysis of the performance of the proposed algorithm. The computational results show the efficiency of the network coding and provide important information for strategic decisions on routing policies and network management https://github.com/lidingxu/wUMCFC.

A Comparative Study on Anonymizing Networks: TOR, I2P, and Riffle Networks Comparison

Background and Objectives: Among miscellaneous networks, onion-based routing network technologies such as The Onion-based Routing (ToR), Invisible Internet Project (I2P), and Riffle networks are used to communicate anonymously by different worldwide users for security, privacy, and safety requirements. Sometimes, these types of networks sacrifice anonymity for the sake of efficient communication or vice-versa. This paper surveys aforementioned networks for investigating their potential and challenges.Methods: Onion-routing networks encapsulate messages in several layers of encryption similar to layers of an onion. The anonymous communication networks are involved dining cryptographers (DC) problem so-called DC-nets, which need sending anonymous message with unconditional sender and untraceable receipt. So, DC-nets must be resistant against traffic analysis attacks although they will attenuate the network bandwidth. In this line, ToR is a free software that provides anonymous communication, I2P networks are based on hidden internet service project which uses tunnelling for anonymous communications, and Riffle networks include a small set of camouflaging servers that provide anonymity for authorized users. This paper presents a comparative study on anonymizing ToR, I2P, and Riffle networks in terms of associated prominent parameters in this vein.Results: The comparison is based on similarities, differences, and challenges in network behaviors. This comparison is beneficial for further researches and future improvements.Conclusion: The review of the current paper reveals that the Riffle networks are more resilient and have great confidentiality and integrity against other onion-based routing networks.

IKN-CF: An Approach to Identify Key Nodes in Inter-Domain Routing Systems Based on Cascading Failures.

Inter-domain routing systems is an important complex network in the Internet. Research on the vulnerability of inter-domain routing network nodes is of great support to the stable operation of the Internet. For the problem of node vulnerability, we proposed a method for identifying key nodes in inter-domain routing systems based on cascading failures (IKN-CF). Firstly, we analyzed the topology of inter-domain routing network and proposed an optimal valid path discovery algorithm considering business relationships. Then, the reason and propagation mechanism of cascading failure in the inter-domain routing network were analyzed, and we proposed two cascading indicators, which can approximate the impact of node failure on the network. After that, we established a key node identification model based on improved entropy weight TOPSIS (EWT), and the key node sequence in the network can be obtained through EWT calculation. We compared the existing three methods in two real inter-domain routing networks. The results indicate that the ranking results of IKN-CF are high accuracy, strong stability, and wide applicability. The accuracy of the top 100 nodes of the ranking result can reach 83.6%, which is at least 12.8% higher than the average accuracy of the existing three methods.

Low power network on chip architectures: A survey

Mostly communication now days is done through system on chip (SoC) models so, network on chip (NoC) architecture is most appropriate solution for better performance. However, one of major flaws in this architecture is power consumption. To gain high performance through this type of architecture it is necessary to confirm power consumption while designing this. Use of power should be diminished in every region of network chip architecture. Lasting power consumption can be lessened by reaching alterations in network routers and other devices used to form that network. This research mainly focusses on state-of-the-art methods for designing NoC architecture and techniques to reduce power consumption in those architectures like, network architecture, network links between nodes, network design, and routers.

QoS Improvement Using In-Network Caching Based on Clustering and Popularity Heuristics in CCN.

Content-Centric Networking (CCN) has emerged as a potential Internet architecture that supports name-based content retrieval mechanism in contrast to the current host location-oriented IP architecture. The in-network caching capability of CCN ensures higher content availability, lesser network delay, and leads to server load reduction. It was observed that caching the contents on each intermediate node does not use the network resources efficiently. Hence, efficient content caching decisions are crucial to improve the Quality-of-Service (QoS) for the end-user devices and improved network performance. Towards this, a novel content caching scheme is proposed in this paper. The proposed scheme first clusters the network nodes based on the hop count and bandwidth parameters to reduce content redundancy and caching operations. Then, the scheme takes content placement decisions using the cluster information, content popularity, and the hop count parameters, where the caching probability improves as the content traversed toward the requester. Hence, using the proposed heuristics, the popular contents are placed near the edges of the network to achieve a high cache hit ratio. Once the cache becomes full, the scheme implements Least-Frequently-Used (LFU) replacement scheme to substitute the least accessed content in the network routers. Extensive simulations are conducted and the performance of the proposed scheme is investigated under different network parameters that demonstrate the superiority of the proposed strategy w.r.t the peer competing strategies.

POSIMNET-R: An immunologic resilient approach to position routers in Industrial Wireless Sensor Networks

Industry 4.0 has increased the interest in employing Industrial Wireless Sensor Network (IWSN) technologies in industrial automation. The advantages range from ease of installation and maintenance to reduced deployment time and infrastructure costs. However, industrial automation has critical requirements regarding network infrastructure, such as reliability and failure tolerance. Therefore, it is imperative to have an adequate placement of sensor and router nodes, to obtain a network with multiple paths, allowing the data to reach management systems within a reasonable time, even in the event of failures. The placement of router nodes has to consider latency, network lifespan, connectivity, and failure tolerance aspects in a possibly hostile environment, with classified areas and obstacles such as silos, tanks and buildings. We present a new approach, called POSIMNET-R, to place IWSN routing nodes in an industrial configuration, which circumvents forbidden areas and obstacles, based on Artificial Immunological Networks. The resulting network offers low failure rates and path redundancy criteria. The results have shown that POSIMNET-R was capable of providing a reliable network with multiple paths and resilience of the used routers equal to 81.50% in the basic case study and 73.66% in the real case scenario.

Assessing the Performance Analysis of OSPFV3 and EIGRP in Applications in IPV6 Analysis for Articles Published in Scopus between 2016 and 2021

The Analysis of common conceptual frameworks associated with Performance analysis of OSPFV3 and EIGRP in applications in IPV6 for analysis of articles published in Scopus between 2016 and 2021 by applying the Corresponding method analysis. The number of times an article is downloaded is also being considered as a measurement instrument or method of analysis. The Corresponding analysis method has analysis 117 articles from 2016 to 2021. All the articles are based on performance analysis of OSPFV3 AND IPV6.IPv6 has gained legitimacy and inevitability as a result of the internet's expansion, which has resulted in IPv4 address space exhaustion. An internet next-generation protocol that will replace eventually IPv4 is IPv6. Using Riverbed Modeler Academic Edition, 2state link protocols’ performance for IPv6, IS–IS and OSPFv3 was compared and tested for the greatest commonly utilized applications enterprise for example remote login, database query, file transfer, web surfing, and email. The major characteristics used to assess performance include IPv6 packets dropped, network convergence time, link utilization, throughput, remote login response time, file upload/download response times, http page response times, email, and database query response time,. The primary goal of this dissertation is to compare, simulate, and assess both routing protocols’ performance in order to decide which one is best for routing IPv6 network traffic. Based on the parameters utilized, the protocol that performed better than the others would be suggested for routing network traffic in IPv6. The study was separated into two scenarios to achieve this goal: the IS–IS and OSPFv3 scenario. After the simulation for the IS–IS scenario was completed, the data from both scenarios were compared and examined using the provided parameters to see which protocol worked better. Based on the majority of the simulation parameters employed, the simulation results showed that OSPFv3 was performed as compared toIS–IS.

A new fog-based routing strategy (FBRS) for vehicular ad-hoc networks

Vehicular ad-hoc network (VANET) plays a significant role in future intelligent transportation systems. The main objective of vehicular ad hoc networks (VANETs) is to improve driver safety and traffic efficiency. Many researchers proposed different schemes to improve communication efficiency. It is quite challenging where vehicles’ speed, Direction, and density of neighbors on the move are not consistent. Although several routing protocols have been introduced to manage data exchange among vehicles in VANETS, they still suffer from many drawbacks such as lost packets or time penalties. This paper introduced a new Fog Based Routing Strategy, which constructs a reliable system of adaptive, stable, and efficient routing networks. FBRS consists of two main phases: System Setup Phase (SSP) and System Operation Phase (SOP). SSP creates a cluster network, collects its nodes’ data, mining routes between them, and ranking paths using Dijkstra’s algorithm into a simplified table. Although, SOP generates a reliable route between the request of any two nodes for a communication channel and maintains the route against any simultaneous crashes. Recent VANET routing protocols have been compared against FBRS. Experimental results have proven the outperforming of the proposed algorithm against recent routing protocols in terms of packet delivery ratio and routing overhead.

Reconfigurable content-addressable memory (CAM) on FPGAs: A tutorial and survey

Content-addressable memory (CAM) is a massively parallel searching device that returns the address of a given search input in one clock cycle. Field-programmable gate array (FPGA)-based CAMs are becoming popular due to their applications in the latest networking systems, e.g., software-defined networks (SDNs) leading to upcoming 5G networks. Ternary CAM (TCAM) implements a routing table in a network router to classify and forward data packets where don’t care bits (X-bits) correspond to multiple addresses. FPGAs do not have a hard-core CAM, although it is a prime element in networking applications. This paper serves as a comprehensive survey on FPGA-based CAM/TCAMs implemented using block random-access memory (BRAM), lookup table RAM (LUTRAM), and flip-flops (FFs). BRAM-based TCAM suffers from the pre-processing of mapping data, requires the data to be in a specific order in some cases, and has a large SRAM/TCAM bit ratio. LUTRAM-based CAM/TCAM suffers from wide bit-wise ANDing, high routing complexity, but has a small SRAM/TCAM bit ratio of 14 compared to 16 in the case of BRAM-based TCAM. Shallow and wide RAM blocks are required to implement large-size RAM-based TCAMs (BRAM-based and LUTRAM-based TCAMs). FF-based TCAMs use FFs as their memory elements and have reduced hardware costs per TCAM bit. However, due to the routing complexity, it suffers from scalability and a large amount of power consumption. The update latency of BRAM-based TCAM and LUTRAM-based TCAM is proportional to the depth of BRAM and LUTRAM, respectively. However, FF-based CAM updates in 1 or 2 clock cycles depending on the availability of input/output pins on target FPGA.

Monitoring an anonymity network: Toward the deanonymization of hidden services

Anonymity networks are an example of Privacy Enhancing Technology (PET) whose historical goal is to avoid censorship, preserve users privacy, and promote freedom of speech. Such networks, however, also provide a “safe haven” for criminal activity: previous research observed a dominance of commerce platforms delivered as hidden services within The Onion Router (Tor) network, undoubtedly the most popular anonymization technology at the time of writing, largely around narcotics and illegal financial services.Extensive research has been conducted on locating hidden services on the Tor network, but a general method that is able, given a service delivered via anonymity network, to effectively produce a list of candidate nodes responsible for delivering the service still remains an open research problem. In this paper we describe the infrastructure we have designed and implemented for monitoring the Invisible Internet Project (I2P) network, which is a smaller scale anonymity network compared to Tor but already proven to be used for illicit activities, and how its output can be used to enable such general method.

Design and implement of robotic arm and control of moving via IoT with Arduino ESP32

Every day, the technologies are expanding and developed with extra things to them. A cloud computing (CC) and Internet of things (IoT) became deeply associated with technologies of the internet of future with one supply the other a way helping it for the successful. Arduino microcontroller is used to design robotic arm to pick and place the objects by the web page commands that can be used in many industrials. It can pick and place an object from source to destination and drive the screws in into its position safely. The robot arm is controlled using web page designed by (html) language which contain the dashboard that give the commands to move the servos in the desired angle to get the aimed direction accordingly. At the receiver end there are four servo motors which are made to be interfaced with the micro controller (Arduino) which is connected to the wireless network router. One of these is for the arm horizontally movement and two for arm knee, while the fourth is for catch tings or tight movement. Two ultra-sonic sensors are used for limiting the operation area of the robotic arm. Finally, Proteus program is used for the simulation the controlling of robot before the hardware installation

An Estimation and Evaluation of Network Availability in Link State Routing Networks

The internet is taking component in a developing feature in every non-public and professional activity. The real-time, delay sensitive and mission-essential purposes, community availability requirement is beforehand for internet carrier providers (ICPs). The loop-loose criterion (LLC) approach has been extensively deployed through numerous ICPs for handling the best network component failure state of affairs in fantastic internet through. The achievement of LLC lies in its inherent simplicity; however, this comes at the rate of letting certain failure. To reap complete failure safety with LLC without incurring significant extra, a singular link protection scheme, hybrid hyperlink protocol (HLP), to reap failure routing. In contrast with in advance schemes, HLP guarantees tall network in a greater surroundings pleasant way. HLP is carried out in stages. Initial level substances a surroundings pleasant LLC primarily based totally on (MNP-e). The complexity of the set of rules is decrease than that of Dijkstra’s set of rules and might gift similar to network availability with LCC (Loop-loose criterion). Moment level substances backup direction safety based on MNP-e, the area totally a minimum type of need to be protected, to fulfill the network requirement. We don't forget those algorithms in a massive spread of associated, real and actual, and the effects display that HLP can achieve lofty network without introducing apparent.

Enhancing Security and Privacy in Local Area Network (LAN) with TORVPN Using Raspberry Pi as Access Point: A Design and Implementation

Network security is designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies. Every person, including organization requires a degree of network security solutions in place to protect it from the ever-growing landscape of cyber threats in the wild today. This paper aims to design and implement TorVPN as an access point using Raspberry Pi in enhancing security and privacy in Local Area Network (LAN). This access point was implemented by using the combination of The Onion Router (Tor) and Virtual Private Network (VPN) services. Then, the graphical user interface application was developed to assist and facilitate the user to access the network securely without having the difficulties to configure and install any software. To determine the effectiveness of the proposed work, there were two experiments involved in this study. Firstly, the confidentiality test which to verify its privacy in keeping the information securely. Secondly, the performance test of the Internet connectivity in terms of ping, download and upload speed. The encourage results was expected as the confidentiality tested on the TorVPN access point network has shown the positive outcome by securing client’s Internet data packet. While, the Internet connectivity is not stable enough, when the client’s IP address changed in the network. Hence, the combination VPN and Tor service using Raspberry Pi as an access point inside the LAN is suitable and secure the information in the network, but do not suggest for user who wants a good Internet connectivity.

The AODV routing protocol with built-in security to counter blackhole attack in MANET

An ad hoc network is a network made of movable nodes built on the fly and constructed dynamically when there is no longer an infrastructure or pre-built network on the scene. The nodes can also perform both end-to-end terminals and shape MANET roles, meaning they contribute to each route's configurations. The data must travel through several intermediate nodes during the route while routing a given flow from a source to a destination. The data should be larger than needed for just a single application use. The intermediate nodes forward data to the intended destination, taking into account the locations to which it must be sent to arrive correctly. The routing protocol in an Ad hoc network (human-made network) uses nodes to look at different device locations and procedures for any data path they choose before deciding on the route and ways in which they exchange data are viable. Anomaly, since the existing trust among the various nodes and dynamic topology, leaves the routing protocols susceptible to Denial of service attacks like a black hole, wormhole, Denial of service, and being non-integrated into a central infrastructure present a condition which MANETs are subject to such as Conventional networks typically work by injecting some control packets and tracking the target's movement once the user is already on the wireless. Still, in a MANET, the attacker acts before the mark has moved into the wireless medium. Maliciously exploiting various routing information has the potential to drive the system into a situation of more significant disorder, which will eventually lead to widespread network failure. This existing AODV attack, called the Blackhole attack, might have worked by purposefully withholding important routing information from end-users who could have benefitted from it, which is just what the adversary does in this task. In this scenario, the data packets are never delivered, and the system suffers a total data loss. The variety of detection and protection techniques employed against the blackhole attacker significantly lower the number of suspects. Therefore, this paper advocate for OSPFV [for wireless LANs] protocol integration with built-in security, where Threshold evaluation and cryptographic verification are employed. In this paper, two protocols: the blackhole attack and the proposed AODV-BS protocols, are simulated on different MANET models, and the two other network metrics are used: Network Packet Delivery Ratio and the normalized Out of Routing Overhead Utilization and Network Delay are calculated, and then their performance is studied to discover the result.

A data-driven intelligent planning model for UAVs routing networks in mobile Internet of Things

Owing to constant progress of wireless communications, the Unmanned Aerial Vehicles (UAVs) routing networks (UAVs-RN) under mobile Internet of Things (MIoT) have been prevalent tools to deal with natural emergencies. But the achievement of effective responses and proper utility, still remains a challenging task. It is required to analyze multi-source data of UAVs-RN, so that optimal planning schemes under MIoT can be found. To bridge such gap, this work mainly takes three aspects of factors into consideration: rapid response, finite budget and uncertain signal fading. Accordingly, a data-driven intelligent planning model for UAVs-RN under MIoT, is put forward in this paper. Data about wildfire happened in local areas of Australia is selected to build experimental scenarios. And two kinds of UAVs, Surveillance and Situational Awareness drones and Radio Repeater drones, are considered in this study. Firstly, the source data is visualized and the internal trend is analyzed to verify true validity. Then, a multi-objective planning model is accordingly established to aggregate multi-source data. At last, a case study is deeply investigated on real-world data to assess the proposed approach and suggest feasible planning schemes.

Connectivity Indices of Intuitionistic Fuzzy Graphs and Their Applications in Internet Routing and Transport Network Flow

Connectivity index CI has a vital role in real-world problems especially in Internet routing and transport network flow. Intuitionistic fuzzy graphs IFGs allow to describe two aspects of information using membership and nonmembership degrees under uncertainties. Keeping in view the importance of CI s in real life problems and comprehension of IFGs , we aim to develop some CI s in the environment of IFGs . We introduce two types of CI s , namely, CI and average CI , in the frame of IFGs . In spite of that, certain kinds of nodes called IF connectivity enhancing node IFCEN , IF connectivity reducing node IFCRN , and IF neutral node are introduced for IFGs . We have introduced strongest strong cycles, θ -evaluation of vertices, cycle connectivity, and CI of strong cycle. Applications of the CI s in two different types of networks are done, Internet routing and transport network flow, followed by examples to show the applicability of the proposed work.

Routing for tourist and excursion bureaus based at parametric network models

This study is devoted to applying parametric network models for the process of defining a guided tour route within route networks on the example of Denmark. This is caused by difficulty in determining variations when organizing guided tours. Under the actual digitization conditions, tourist and excursion bureaus are being restructured from static organizations administering various excursions into dynamic ones. They are actually getting adjusted to the customers’ needs and demands, taking into account the actual possibilities for covering a certain topic by the tour party within a route. The main problem encountered by tourist and excursion bureaus is the following. Although the nomenclature of presented guided tours is established by the economic entity independently, those are not always carried out according to a clearly defined itinerary and on the same conditions for all participants. When providing such services, customers’ demands and service peculiarities are not known in advance. The purpose of the present study is to provide a substantive basis for routing in tourist and excursion bureaus, based on parametric network models and taking into account the peculiarities of dynamically adaptable tables containing the best routes. To achieve the research goal, network planning methods were used, such as analytical, tabular, cloud computing in the AnyLogic Cloud environment. As a result of the study, a substantive basis of routing of the tourist route was presented for tourist and excursion bureaus, through their parametric network models. The study was implemented at the sample of the Denmark Tour -Your Guide Office, a company founded within cooperation with Russian, Ukrainian, and Denmark partners and providing travel services within the Denmark tourist market. The Office includes about 20 affiliates in Denmark, where route networks have already been adapted to designing tours in practice and parameterization of such networks is well underway, in particular by shifting the focus from the route distance rate to minimization of transfers between attraction sites. However, to provide a substantive basis for the routing in a tourist office, parameters of the routing networks should be determined not only based on the list of actions (activities) to be carried out, but also on their minimum and maximum possible duration. A lack of due attention to the servicing time for the tour groups will lead to breaking tour schedules. Thus, in 2020, as a result of the inefficient parameterization at Denmark Tour - Your Guide, about 5-6 tours around Aalborg and its vicinity were cancelled monthly. Denmark Tour- Your Guide incurs monthly profit losses at 15% in 4-6 tours around Aarhus and its surroundings, Jursland peninsula, rated at a fixed cost, as the result of payment of a fixed cost for the selected excursions. A similar situation, with breaking tour schedules and monthly losses incurred, is common with tourist and excursion bureaus in various countries around the world, including Ukraine. According to the results of the study, it is marked that the routing of tourist itineraries designed by tourist agencies, based on parametric network models turns their static time reserves and operational metrics into dynamic values depending on the duration of the tour activities. This not only ensures following schedules properly in all tours but also minimizes monthly profit loss, at an estimated EUR 2,250 for the Aalborg and its surroundings routes. Meanwhile, there may be situations where it is not possible to change the total tour cost. For example, in the company Denmark Tour - Your Guide, when working with intermediate parties, this price is fixed. To prevent incurring monthly losses within 15% of the profits for 4-6 tours of Aarhus and its surroundings, Jursland peninsula, Aalborg and Surroundings, it is necessary to make some quite specific adjustments in some activities at the sites. These should take into account the time reserve values on the longest route. A special tour activity complex is to be completed, with a maximum difference in early and late schedule times, standard and urgent pricing for the site operations). A procedure is compiled for minimizing losses in routes (over 8K euro annually), providing for completion of the activity complex within the schedule with a minimum additional charge to the operating metric (the route price), since it is not reimbursed by the tourists. It is important that the results presented should identify the path adjustments of each route simultaneously, taking into account the actual time reserve (available based on the tour group location and the previouisly completed schedule items on the tour). Prospects for practical implementation of the presented substantiation basis for the itinerary routing to be used in tourist and excursion bureaus, based on parametric network models, are in establishing facilities for creating dynamic graphic images of the whole tour procedure, in the form of a directed graph of the route network.

Bioreactor for the cultivation of Arthrospira platensis under controlled conditions

A vertical flat-type bioreactor consisting of transparent polyethylene (food safe) was constructed, which is characterized by a flexible design and allows the adjustment of a light path of 1 cm – 8.5 cm and a working volume of 1.5 l – 4 l. To characterize the performance of the bioreactor, cultivation experiments were performed with the cyanobacterium Arthrospira platensis (AP). The growth was assessed continuously by monitoring optical density and intermittently by measuring the dry weight of the AP biomass. An on-line measurement technique for estimating biomass production rate in a photosynthetic microalgae culture was developed. The oxygen produced by AP in the culture medium was flushed out sparging using a mixture of air and CO2 (1%). Factors which might influence the AP growth were monitored: pH, temperature, oxygen concentration and the filling level were corrected automatically to compensate evaporation losses. As an example, the huge influence of the light intensity on the AP growth was tested. The increase of the photon flux density of 15 to 1200μmol/(l · d) led to a 22-fold increase of the productivity and a 3.1-fold shorter doubling time. Using an online measurement technique - together with the control of the growth process via a wireless local area network (WLAN) router and virtual private network - allows monitoring the growth of Arthrospira platensis remotely.

Routing Performance Evaluation of a Multi-Domain Hybrid SDN for Its Implementation in Carrier Grade ISP Networks

Legacy IPv4 networks are strenuous to manage and operate. Network operators are in need of minimizing the capital and operational expenditure of running network infrastructure. The implementation of software-defined networking (SDN) addresses those issues by minimizing the expenditures in the long run. Legacy networks need to integrate with the SDN networks for smooth migration towards the fully functional SDN environment. In this paper, we compare the network performance of the legacy network with the SDN network for IP routing in order to determine the feasibility of the SDN deployment in the Internet Service provider (ISP) network. The simulation of the network is performed in the Mininet test-bed and the network traffic is generated using a distributed Internet traffic generator. An open network operating system is used as a controller for the SDN network, in which the SDN-IP application is used for IP routing. Round trip time, bandwidth, and packet transmission rate from both SDN and legacy networks are first collected and then the comparison is made. We found that SDN-IP performs better in terms of bandwidth and latency as compared to legacy routing. The experimental analysis of interoperability between SDN and legacy networks shows that SDN implementation in a production level carrier-grade ISP network is viable and progressive.
