Implementation of Ad-Hoc Protocol On Tandem Multihop Wireless Network

The utilization of Internet of Things (IoT) technology, especially in remote areas, is still relatively low, even though the technology is required to implement smart farming or smart villages, which aims to improve the quality of life of people in rural areas. The high investment cost for IoT networks that still use cellular networks or Wi-Fi is one of the causes of the slow implementation of this technology. Our previous research has developed an alternative network for IoT devices in remote areas with the concept of a Tandem Multihop Wireless Network focusing on developing simple message scheduling. This research focuses on implementing ad-hoc routing protocols in tandem with multi-hop wireless to analyze the advantages and disadvantages of the protocol. Each sensor periodically sends data to the monitoring server via IoT devices on each tower. The scenario was implemented using MININET-WIFI. Evaluations were carried out to determine delivery probability, latency average, and jitter. In general, the two Ad-Hoc protocols tested, namely OLSR and BATMAN, had the same performance when the data sent was 1 MB, but when the data size was increased to 2 MB, the OLSR routing protocol on several nodes had better performance than BATMAN.

Analysis Study of Routing Protocols in MANET for Disaster Management

A unique instance of a wireless ad hoc network that is non-centralized, self-organized, and self-managed is known as a mobile ad hoc network(MANET). MANET used in different areas of life like a rescue operation, real-time information, interpersonal communication, information sharing and network portioning. MANET has dynamic change in nature of both its topology and nodes in order to deliver data quickly. Due to Mobility nature in nodes, there is a lot of chances of routing design issues between the nodes. There is a list of routing protocol each one has its special characteristic in Specific areas have been designed and compared their attributes on different parameters. This report gives a clear picture and a comparison of various MANET routing techniques with their limitation in ad-hoc routing network.

Maintaining Effective Node Chain Connectivity in the Network with Transmission Power of Self-Arranged AdHoc Routing in Cluster Scenario

Mobile Ad hoc Networks (MANETs) are intended to work without a fixed framework and provide dependable interchanges to ground vehicles, boats, airplanes, or people and structure a self-mending process that will empower persistent correspondences in any event, when at least one of its nodes are debilitated or briefly expelled from the system. Notwithstanding, MANETs demonstrate themselves to be progressively harder to create for enormous systems with hundreds or thousands more nodes than initially envisioned. In our proposed technique, the node switches its communication mode depending on the connectivity of the adjacent nodes. The transmission power of each node will be calculated with the help of two major scenarios i.e., tree scenario and zone scenario. The autonomous clustering of the nodes among the tree and the zone scenario will be channelized by a comparison of the transmission power (residual energy) among the nodes. The inter and the intra communication of the node is also discussed in the paper. The result will be carried out by the simulation work in various perspectives, such as checking the percentage level of malicious nodes, traffic density, transmission power, and the longevity of nodes.

Networking in Vehicular Ad-Hoc Networks (VANET) for Accident Prevention

Abstract: VANET (Vehicular Ad Hoc Network) is an emerging technology for intelligent inter-vehicle communications. It is a specialized derivation of pure multi-hop ad hoc networking that is currently undergoing industrial prototyping; however, the dreamed idea of a general purpose vehicular ad hoc network is still a long way off. For the past few years, vehicular communication has been a hot topic. The VANET objective is to use short-range wireless technology to provide road safety and commercial comfort applications. Many routing protocols have been designed specifically for such networks, with the majority of them attempting to make use of information that may be available at the vehicle by the time a routing choice is required. We have investigated the AODV and GPSR in this study. Keywords: AODV, GPSR, Vehicular Ad Hoc Networks, Ad-Hoc Routing, Routing Protocols.

SIMULATION AND COMPARISON OF AD HOC NETWORKS ROUTING PROTOCOLS BASED ON OPNET

Ad-hoc routing algorithm has always been a core problem in research of ad-hoc networks. In order to be able to deal with various routing protocol problems on an ad-hoc network like poor validity and large control overhead, this paper classify and compare ad-hoc network routing protocols through OPNET simulation tool and focus on testing two routing protocols' performance namely, table-driven and on-demand routing protocol. The Destination Sequenced Distance Vector routing protocol is the most used table-driven routing protocols, While AODV and DSR routing protocols are the two most used on-demand routing protocols. The performance of these three protocols is simulated with a variety of packet delivery functions, average end-to-end delays, and routing loads. These protocols are also analyzed and compared. The simulation results show that for a high mobility environment, the on-demand routing protocol is the best option.

Energy Factor Based Routing Algorithm for Lifetime Enhancement in Mobile Ad-Hoc Networks

Energy consumption and dissipation of mobile nodes is considered as one of the significant aspect affecting the entire lifetime of Mobile Ad-Hoc Networks (MANETs), as the nodes depends on limited battery power. In addition, spatial and temporal characteristics of mobile nodes also make energy imbalance in the network. Towards this, there are several studies that emphasis on improving the network lifetime and reliability by altering the existing MANET routing protocols. In this paper, an Energy Factor based Ad-Hoc On Demand Distance Vector routing algorithm (EF-AODV) is proposed in MANETs for lifetime enhancement. The proposed technique includes two algorithms by leveraging the cross layer paradigm. Firstly, proposed EF-AODV dynamically chooses intermediate nodes based on battery power, and mobility of the nodes in the direction of destination. Secondly, for uniform energy consumption, we calculate the energy factor at each intermediate mobile node by considering the sleep and ideal states of the nodes along with mobility. Further, the energy factor is considered as a key metric to obtain the optimal path from the source to the destination to balance the energy disparity in the network, leading to reduced delay in packet transmission. The path with highest energy factor value is selected for networking of data packets. Upon extensive simulation using Network Simulator (NS-2.34), we illustrate that the proposed EF-AODV outperforms over existing ad-hoc routing approaches under the various performance metrics.

Enhancing Reactive Ad Hoc Routing Protocols with Trust

In wireless ad hoc networks, security and communication challenges are frequently addressed by deploying a trust mechanism. A number of approaches for evaluating trust of ad hoc network nodes have been proposed, including the one that uses neural networks. We proposed to use packet delivery ratios as input to the neural network. In this article, we present a new method, called TARA (Trust-Aware Reactive Ad Hoc routing), to incorporate node trusts into reactive ad hoc routing protocols. The novelty of the TARA method is that it does not require changes to the routing protocol itself. Instead, it influences the routing choice from outside by delaying the route request messages of untrusted nodes. The performance of the method was evaluated on the use case of sensor nodes sending data to a sink node. The experiments showed that the method improves the packet delivery ratio in the network by about 70%. Performance analysis of the TARA method provided recommendations for its application in a particular ad hoc network.

A Scalable Secure Routing Protocol for Managed-Open Mobile Ad-Hoc Networks

Mobile Ad-hoc networks are getting progressively more popular. In such networks, nodes are continuously moving, hence, seeking an efficient route from a particular source to projected destination is a vital issue. Moreover, choosing a secure route is a tough area to deal with since adversaries may include themselves within these routes unless a strict secure procedure is implemented along with routing protocols. In managed-open environment, such as that formed by peers at a conference, using already established infrastructure as a starting point for assuring security is likely. Thus, this research proposes a novel paradigm of routing protocol named S-Octopus. Through tackling with area as sectors and utilizing restricted directional flooding, S-Octopus tries to achieve improved scalability. Moreover, S-Octopus seeks to increase robustness and alleviate single point of failure and compromise problem via picking up numerous sector certificate authorities. A qualitative comparison among S-Octopus and some other secure Ad-hoc routing models is presented in this paper.

Fuzzy Aggregator Based Energy Aware RPL Routing for IoT Enabled Forest Environment

Forested areas are extremely vulnerable to disasters leading to environmental destruction. Forest Fire is one among them which requires immediate attention. There are lot of works done by authors where Wireless Sensors and IoT have been used for forest fire monitoring. So, towards monitoring the forest fire and managing the energy efficiently in IoT, Energy Efficient Routing Protocol for Low power lossy networks (E-RPL) was developed. There were challenges about the scalability of the network resulting in a large end-to-end delay and less packet delivery which led to the development of Aggregator-based Energy Efficient RPL with Data Compression (CAA-ERPL). Though CAA-ERPL proved effective in terms of reduced packet delivery, less energy consumption, and increased packet delivery ratio for varying number of nodes, there is still challenge in the selection of aggregator which is based purely on probability percentage of nodes. There has been research work where fuzzy logic been employed for Mobile Ad-hoc Routing, RPL routing and cluster head selection in Wireless Sensor. There has been no work where fuzzy logic is employed for aggregator selection in Energy Efficient RPL. So accordingly, we here have proposed Fuzzy Based Aggregator selection in Energy-efficient RPL for region thereby forming DODAG for communicating to Fog/Edge. We here have developed fuzzy inference rules for selecting the aggregator based on strength which takes residual power, Node degree, and Expected Transmission Count (ETX) as input metrics. The Fuzzy Aggregator Energy Efficient RPL (FA-ERPL) based on fuzzy inference rules were analysed against E-RPL in terms of scalability (First and Half Node die), Energy Consumption, and aggregator node energy deviation. From the analysis, it was found that FA-ERPL performed better than E-RPL. These were simulated using MATLAB and results.

A Cross-layer Method for Identifying and Isolating the Blackhole Nodes in Vehicular Ad-hoc Networks

ABSTRACT Vehicular Ad-hoc Network (VANET) is a set of intelligent vehicles that communicate without a fixed infrastructure. The communication between each source/destination pair is done by using routing protocols. On-demand multipath distance vector (AOMDV) is one of the most known ad-hoc multipath routing protocols used in VANETs. The decentralized nature of VANET makes this type of network vulnerable to various attacks, such as blackhole attack. In such attack, the malicious vehicle aims to make the communication unavailable. To achieve this goal, the malicious vehicle persuades the source to send its data packets through it because it has the fresher route toward the destination. This is done by forging routing information. After receiving the data packets, the malicious vehicle deletes them instead of forwarding them to their intended destinations. This paper introduces a new Cross-Layer method (CRAOMDV) where information is shared between MAC and network layers to detect and ignore the malicious vehicles in VANETs. Our experiments used the simulator NS2 and SUMO for the generation and simulation of real mobility scenarios. The evaluation results demonstrate the efficiency of CRAOMDV compared to AOMDV under blackhole attack in terms of improving the packet delivery and reducing the average end-to-delay and the routing overhead.

MRIRS: Mobile Ad Hoc Routing Assisted With Intelligent Reflecting Surfaces

A mobile ad hoc network (MANET) poses significant challenges such as route failure and end-to-end delay due to the decentralized nature of mobile ad hoc wireless networks, mobility of devices, and resource constraints. Motivated by this, in this work, a new routing protocol by implementing intelligent reflecting surfaces (IRSs) in MANET, called MRIRS, is proposed. The developed MRIRS investigates the role of IRS as an intermediate node which helps not only for multi-flow multi-path routing even in non-line-of-sight (NLoS) scenarios but also supports delay minimization in the route discovery phase and helps with interference-avoiding channel assignment to the primary users (PUs). Comparison in terms of packet delivery ratio (PDR) and end-to-end delay (PD) averaged on 40 topologies based on the same source and destination pair with 3 flows shows that MRIRS has an 8% improvement in PDR and 800 msec improvement in PD. In environments with 8 m/s average node speed, MRIRS shows 114.88 kbps improvement in terms of throughput where 15.97% link failure is recorded on average. In environments with 16 m/s, link failure is around 24% where it is almost 98% for other routing protocols.

Proposed emerged and enhanced routing protocols for wireless networks

The problem motivation of this work deals with how to control the network overhead and reduce the network latency that may cause many unwanted loops resulting from using standard routing. This work proposes three different wireless routing protocols which they are originally using some advantages for famous wireless ad-hoc routing protocols such as dynamic source routing (DSR), optimized link state routing (OLSR), destination sequenced distance vector (DSDV) and zone routing protocol (ZRP). The first proposed routing protocol is presented an enhanced destination sequenced distance vector (E-DSDV) routing protocol, while the second proposed routing protocol is designed based on using the advantages of DSDV and ZRP and we named it as DS-ZRP routing protocol. The third proposed routing protocol is designed based on using the advantaged of multipoint relays in OSLR protocol with the advantages of route cashing in DSR protocol, and we named it as OLS-DSR routing protocol. Then, some experimental tests are doing by demonstration case studies and the experimental results proved that our proposed routing protocols outperformed than current wireless routing protocols in terms of important network performance metrics such as periodical broadcast, network control overhead, bandwidth overhead, energy consumed and latency.

Performance analysis of multi-hop routing protocols in SDN-based wireless networks

Wireless cellular networks have rapidly evolved to be software-defined in nature. This has created opportunities to improve their performance. One such opportunity is through enabling programming and integration of multi-hop device-to-device (MD2D) at the edge. However, efficient integration of MD2D at the edge requires a highly adaptable and scalable routing protocol, where its development is underpinned through understanding of which type of current routing characteristics and architectures are suitable over dynamic networking conditions. To develop such understanding, we conducted a detailed analysis and performance study on three routing protocols, namely virtual ad-hoc routing protocol-source based (VARP-S) Abolhasan et al. (2018), SDN-based multi-hop device-to-device routing protocol (SMDRP) Abdollahi et al. (2019) and hybrid SDN architecture for wireless distributed networks (HSAW) Abolhasan et al. (2015). Our investigations illustrate that VARP-S and SMDRP perform best in terms of energy consumption and cellular routing overhead. However, HSAW shows better performance in terms of end-to-end (E2E) delay and packet loss over lower network and traffic densities.

Network Architecture and Wireless Ad Hoc Routing for Airborne Internet Services

SO-AODV

MANET has emerged as an eager field for supporting disaster response and prevention applications like climate and weather observation, tracking, tsunamis, wildfire and emergency rescue operations, underwater level navigation, etc. In this paper, a new ad-hoc routing protocol named SO-AODV (Secured and Optimized Ad-Hoc On-Demand Distance Vector) is proposed for secured and optimized communication in any disaster like situations. For shortest route selection a technique called pigeons swarm optimization (PiSO) is used that also leads to minimize the hop count in selected optimal route. Lightweight digital watermarking (LDW) is used that ensures the authenticity of “hello” packets. For security of event messages, cyphertext stealing technique (CST) is used with encryption qu-Vanstone elliptic curve cryptography (qV-ECC) based public key cryptography. The qV-ECC generates public key. Experiments are conducted using NS2 and performance is evaluated and compared over AODV for several metrics (i.e., packet delivery ration, throughput, end-to-end delay, security, and hop count).

Investigating the Energy Efficient Routing Protocol for Wireless Sensor Networks

A Wireless Sensor Network(WSN) consists of chain of sensors with capabilities of consuming energy for sensing, computing, and wireless communication to track physical device and relay their data to a base station cooperatively via the network. Efficient path for the processing of data in WSN and also to identify the active devices in the path. The ad-hoc networks which are active in WSN due to protocol, they facilitate versatility that often alters the topology. The Energy Efficient Zone based Routing Protocol (ZBEEP) which is the latest protocols in this direction, and the most common is On Demand Distance Vector Ad-hoc routing protocols. In ABODV and ZBEEP protocols using Network Simulator, I simulated this Black Hole Attack and tried that in the case of ZBEEP protocol the effect of energy due to Black Hole Attack is ineffective and better as compared to ABODV. I used two service quality metrics, such as Packet Transmission Ratio and Through-put, to help my opinions.

Adapting Ad-hoc Routing Protocol for Unmanned Aerial Vehicle Systems

The field of the ad-hoc network and its routing protocols had attracted a lot of researchers for many years, due to the various usage of the ad-hoc networks in many fields and especially the field of Unmanned Aerial Vehicles (UAVs). Routing protocols in the ad-hoc network are the main focused problem, for their characteristics and role during the communication process of the ad-hoc networks, with its different types. In this paper, we are going to analyze and sheds the light on the performance of ad-hoc routing protocols, for both Flying ad-hoc network (FANET) and vehicle ad-hoc network (VANET) when applying three different ad-hoc routing protocols, respectively Reactive routing protocol, Proactive routing protocol, and Hybrid routing protocol, in order to shed light on the ambiguous misunderstanding of ad-hoc routing protocols functionality and to choose the best routing protocol to be used and adapted for UAVs.

PUSR: Position Update Secure Routing protocol for MANET

Mobile ad hoc network is a self-organizing wireless network, which is formed by the wireless mobile devices without any centralized infrastructure. The mobile nodes in the network are mainly affected by the inherent characteristics such as unpredictable network topology and open wireless medium. Especially, the presence of selfish nodes in the network creates the packet loss and affects an entire communication system. In this paper, the hash function with position updating algorithm is proposed in the Ad hoc On-Demand Distance Vector (AODV) routing protocol for improving the security against the selfish nodes. The AODV routing protocol is used to transmit the data packets from the source to the destination. Therefore, the Prevention of Selfish Node using Hash Function (PSNHF) with position update algorithm is proposed for minimizing the packet loss through the network. The performances of proposed AODV-PSNHF method are analysed in terms of energy consumption, throughput, Packet Delivery Ratio (PDR), packet loss and normalized routing load. In addition, the AODV-PSNHF method is compared with the existing trust-aware ad-hoc routing protocol (T2AR). The selfish node identification using hash function and positioning update using AODV-PSNHF method provides reliable and secure data transmission under selfish nodes and shows better performance in terms of throughput, packet delivery ratio and packet loss. For 2% of malicious nodes the PDR of the AODV-PSNHF method is 89%, it is 9% higher when compared to the T2AR protocol whose PDR% is only 80% for the same.

Evolutionary cross-layer interactive model for sensor communication

Cross-layer based approach has significant benefits compared to conventional layered based routing approach in wireless sensor network (WSN); however, existing approaches in this direction have been found to offer a symptomatic solution towards any problem. The proposed system emphasises on establishing interactivity among the logical link layer, MAC layer, and network layer. Usage of CLIF model ensures message ranking mechanism that assists in tagging the priorities to the control message which facilitates to offer better signal processing services by WSN. Hence, an evolutionary novel approach is introduced in this paper which predominantly emphasise on the interaction between the cross-layer. The model is developed to 1) ensure better network lifetime, 2) incorporate better supportability to ad-hoc routing policies, 3) leverage cooperative transmission scheme, and 4) maintain sustainability between data forwarding mechanism and energy consumption. The outcome of the simulation result shows that the proposed scheme offers minimal delay, maximised data delivery, and reduced energy consumption in WSN.
