WIRELESS LAN DESIGN AND FUTURE INTERNET ARCHITECTURE

In this research thesis, an advance work is being done on the Wireless Local Area Network (WLAN) design and future internet architecture for intrusion detection. There has been a large shift worldwide in using technology in almost every aspect of our lives. This trend has been termed in many industries as the "Internet of Things" (IoT), where the Internet and cloud- based activities are seeing more and more use for control, monitoring and data storage applications. As stated earlier, these assumptions were made because of the extreme difficulty in obtaining any related telemetry from an actual WLAN system or business-critical network. To improve the validity of the simulation, it would be beneficial to obtain even sanitized telemetry from an actual system. Then, the simulation could be refined to better reflect the dynamics of the signals in a real system. If actual WLAN system data is unobtainable, then the test by itself can be modified to reflect more processes seen in these systems. First, a small flow loop with sensing and control elements could be constructed and driven by the servers of the test bed. The primary server in the test bed that acts as the WLAN server could then be programmed to poll the sensors, issue commands and collect data. Time synchronous averaging techniques are used to resample telemetry sources that have different sampling rates. The research provides several case studies to prove the efficacy of the newly developed variable grouping technique for WLAN. Recall that variable grouping methods are needed to extract sets or subsets of variables that give the lowest model prediction errors. The research also presents AAKR and AAMSET model results for several successfully detected intrusion activities from two different data sets. The models utilized four different clusters of telemetry taken from the Linux kernel to determine which class of telemetry was more effective for intrusion detection. The knowledge-based system is certainly the most numerous and widely used type that uses signatures or features of known wireless network attacks for detection purposes. While this type is easy to implement and has a low rate of false/missed alarms, it will always miss the so-called zero-day wireless network attacks. Recall that a zero-day wireless network attack is a new, unknown intrusion. Because the knowledge-based system has never seen a zero-day intrusion event, it will classify this new behavior as normal. In contrast, the behavior-based system can detect known and zero-day wireless network attacks with an accuracy of 97.86% correctly. This type uses data-driven modeling techniques to learn normal system behavior. Once trained, any future monitored telemetry that deviates from this learned behavior will be labeled as an intrusion event.

Currently technology is developing rapidly and has begun to enter into all aspects of the field, one of which is the development of network technology in the field of education. However, not all of these network technology developments have been implemented in SMK Negeri 5 Serang City, so that problems arise in the laboratory environment about how to analyze and utilize network technology to assist the teaching and learning process in the laboratory room. Network technology that will be applied later can assist in sharing data or devices in one laboratory room. Therefore, the author provides a solution by analyzing the need to design a local area network using a star topology. For the design of the local area network, this is only a design of the shape of the room with the number of computers that have been connected to the network. Where the results obtained from this research are in the form of analysis and design of local area networks in the laboratory of SMK Negeri 5 Serang City which can later be implemented further so that they can be applied in assisting the teaching and learning process in the laboratory space of SMK Negeri 5 Serang City

It provides a high degree of regularity and scalability, which conform well to a design and realization of distributed systems involving a large number of computing elements. In this paper, the routing of a message is investigated on the WK-recursive network, which is key to the performance of this network. We present an efficient shortest path algorithm on the WK-recursive network, which is simpler than Chen and Duh[2] in terms of design complexity.

Advanced architectures for high-performance quantum networking

As practical quantum networks prepare to serve an ever-expanding number of nodes, there has grown a need for advanced auxiliary classical systems that support the quantum protocols and maintain compatibility with the existing fiber-optic infrastructure. We propose and demonstrate a quantum local area network design that addresses current deployment limitations in timing and security in a scalable fashion using commercial off-the-shelf components. First, we employ White Rabbit switches to synchronize three remote nodes with ultra-low timing jitter, significantly increasing the fidelities of the distributed entangled states over previous work with Global Positioning System clocks. Second, using a parallel quantum key distribution channel, we secure the classical communications needed for instrument control and data management. In this way, the conventional network that manages our entanglement network is secured using keys generated via an underlying quantum key distribution layer, preserving the integrity of the supporting systems and the relevant data in a future-proof fashion.

Design, Deployment and Implementation of Local Area Network (LAN) at BAEC Head Quarter

A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of interconnected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines. Communication between remote parties can be achieved through a process called Networking, involving the connection of computers, media and networking devices. When we talk about networks, we need to keep in mind three concepts, distributed processing, network criteria and network structure. The purpose of this Network is to design a Local Area Network (LAN) for a BAEC (Bangladesh Atomic Energy Commission) Head Quarter and implement security measures to protect network resources and system services. To do so, we will deal with the physical and logical design of a LAN. The goal of this Network is to examine of the Local Area Network set up for a BAEC HQ and build a secure LAN system.

Investigation and Evaluation of IEEE 802.11n WLANs Link Features Performance Under Single Host and Concurrent Communication

For an efficient design of wireless local-area networks (WLANs), the simulation tools are important to accurately estimate the IEEE 802.11n/ac link features for WLANs. However, this true simulation of network behavior is critical in designing high-performance WLANs. Through testing, analysis, and modeling of the proposed scheme repetitively, the design of the WLAN can be enhanced with a small budget before making its practical implementation. Many network simulation tools have been established to give solutions for this request and ns-3 is the most widely used tools among them by the research industry as an open-source network simulator. In this paper, we examine the various link features of the 802.11n WLANs under several conditions. We investigate the effects of 802.11n WLAN modulation and coding schemes (MCSs), 20MHz single channel or 40 MHz bonded channel, guard intervals (GI), frame aggregation, data encoding, number of antennas and their data rate, and link distance features of 802.11n WLAN in ns-3 when only a unique host connects with the access point (AP) and generates data traffic. Besides, the performance for an enterprise scenario proposed by the IEEE 802.11ax study group is evaluated when several hosts are simultaneously creating traffic with their associated APs. The results demonstrate that ns-3 support most of the link features of the 802.11n protocol with significant accuracy.

Hitting Times for Random Walks on Sierpiński Graphs and Hierarchical Graphs

AbstractThe Sierpiński graphs and hierarchical graphs are two much studied self-similar networks, both of which are iteratively constructed and have the same number of vertices and edges at any iteration, but display entirely different topological properties. Both graphs have a large variety of applications: Sierpiński graphs have a close connection with WK-recursive networks that are employed extensively in the design and implementation of local area networks and parallel processing architectures, while hierarchical graphs can be used to model complex networks. In this paper, we study hitting times for several absorbing random walks in Sierpiński graphs and hierarchical graphs. For all considered random walks, we determine exact solutions to hitting times for both graphs. The obtained explicit expressions indicate that the hitting times in both graphs behave quite differently. We show that the structural difference of the graphs is responsible for the disparate behaviors of their hitting times.

Analysis of EMC problems with the purpose of developing an effective method of WLAN design on the basis of information systems considering electromagnetic

The article analyzes the scope, technologies and principles of wireless local area networks, which allowed to mark the “bottlenecks” of these technologies, which need special attention when designing: the problem of hidden node; mutual interference between neighboring cells (intrasystem EMC); intersystem interference; providing QoS for responsible applications; expansion of wireless local area networks; the impact of network deployment features. The methods used to solve EMC problems in wireless local area networks are shown and their efficiency is analyzed: the mechanism of access to the transmission medium; IEEE 802.11e (QoS) standard; additional standards designed to reduce the impact of interference (802.11 h and k); coding and modulation. It is shown that the accounting of intrasystem and intersystem interference should be carried out in the early stages of design of wireless local area networks. It is shown that the existing mechanisms of access to the transmission medium are designed to organize the conflict-free operation of transceivers within a single access point and are vulnerable to interference created by transmission stations of neighboring access points. The dynamic sensitivity control algorithm is aimed at partially solving this problem, however, the main disadvantage of the DCC algorithm proposed for use in Wi-Fi 6 is that stations located near access points have a higher probability of access to the environment due to a higher signal level. Relative to electromagnetic interference, which leads to a shorter detection range of the carrier. That requires the development of advanced mechanisms to control the sensitivity of the service area of access points. Based on the analysis, a conclusion is made about the need to develop a methodology for designing wireless local area networks based on information systems, taking into account electromagnetic interference. Which will reduce the time of their design and increase the efficiency of their further operation.

Design and Development of Virtual Local Area Network and Securing Network using Network Address Translation

To develop and implement a Virtual Local Area Network by using sub-netting and to find the optimized IP depended on host number. When a company purchases web hosting from Internet Service Provide they will purchase several static addresses. As a result an automated system to store the information about assigned IP address and solve the problem. The main objective is to develop and discuss about the various Internet Service Provider (ISP) and securing the network by using Network Address Translator (NAT) and Access Control list (ACL). Static routes or a direct connection to the destination network i.e. a router might be running both an Open Shortest Path First version 3 (OSPFv3) process and a Routing Information Protocol (RIP) process. If the OSPF protocol is advertised to optimize the routes by RIP protocol, it is said to be redistributing RIP. The detailed information about the Dynamic protocols such as RIP, OSPFv3, EIGRP etc.., its standards, functionality and internetworking issues in the networking domain are observed and troubleshoot the problems in the internetwork connectivity using the CISCO routers and end devices and hence to design a simple network with tool with multiple routing protocols in IPv6 domain and redistribute for end-to-end communication.

Backbone-Assisted Wireless Local Area Network

This article presents a cross-layer design of backbone-assisted wireless local area network (WLAN) for dense WLAN deployment. The popularity of 802.11-based WLANs leads to dense WLAN deployment in geographically limited space, including dense access points (AP) and dense users. With dense APs, an AP could overhear packets destined for other APs. Backbone-assisted WLAN is a new system architecture where cooperative APs share the overheard packets through a backbone network, thereby reducing packet retransmission and improving system throughput. Conventional WLAN, such as Wi-Fi, uses Stop-and-Wait ARQ. This article argues that Stop-and-Wait does not work well with backbone-assisted WLAN because of large backbone delays. We first show that with a variant of Selective Repeat ARQ tailored for backbone-assisted WLAN, a single-user backbone-assisted WLAN system can achieve substantial throughput improvement over that with Stop-and-Wait ARQ. Then, we put forth a new system architecture targeted for dense users, referred to as network-coded backbone-assisted WLAN, in which multiple users are allowed to transmit simultaneously. A distinguishing feature of this system is the joint use of physical-layer network-coding (PNC) decoding and multiuser decoding (MUD) in multipacket reception. This article is the first attempt to design an ARQ for multiuser backbone-assisted WLAN. Our overall system design solves a PNC sequence obfuscation problem and addresses long packet latency in Selective Repeat ARQ. Experiments on our software-defined radio prototype indicate that network-coded Ethernet-backbone-assisted WLAN can achieve high system throughput and low packet latency. Specifically, the system throughput can outperform an MUD-only multiuser WLAN and a single-user WLAN by 60 and 100 percent, respectively. Overall, we believe that network-coded backbone-assisted WLAN is a viable solution for boosting throughput and reducing latency in dense WLAN environments.

Spectral Properties of Extended Sierpiński Graphs and Their Applications

The eigenvalues of a graph present a wide range of applications in structural and dynamical aspects of the graph. Determining and analyzing spectra of a graph has been an important and exciting research topic in recent years. In this paper, we study the spectra and their applications for extended Sierpinski graphs, which are closely related to WK-recursive networks that are widely used in the design and implementation of local area networks and parallel processing architectures. Moreover, a particular case of extended Sierpinski graphs is the dual of Apollonian network, which displays the prominent scale-free small-world characteristics as observed in various real networks. We derive recursive relations of the characteristic polynomials for extended Sierpinski graphs at two successive iterations, based on which we determine all the eigenvalues, their corresponding multiplicities and properties. We then use the obtained eigenvalues to evaluate the number of spanning trees, Kirchhoff index of extended Sierpinski graphs, as well as mean hitting time and cover time for random walks on the graphs.

Energy-Efficient WLANs With Resource and Re-Association Scheduling Optimization

Recently, a number of WiFi access points (APs) have been densely deployed to provide widely available, high-performance Internet services. As such, an energy efficiency issue becomes crucial toward the design of green wireless local area networks (WLANs). In this paper, we propose a resource and re-association scheduling algorithm (referred to RAS) based on Benders’ decomposition to reduce the energy consumption. In particular, we endeavor to aggregate WLAN users on the small number of APs and turn off many APs without compromising users’ quality of experience (QoE) and system coverage. We conduct the analysis by using real trace data and formulate the energy minimization as the mixed integer nonlinear programming (MINLP) problem. We then transform and solve the original problem through the RAS algorithm. For practical implementation, we further propose the fast RAS (Fast-RAS) algorithm to relax the binary integer constraints and transform the MINLP problem into the nonlinear programming (NLP) problem. The relaxed problem then can be solved by using Feasible Pump algorithm with the reduced computational complexity. We evaluate the performance of RAS and Fast-RAS algorithms via extensive simulations. The results demonstrate that the Fast-RAS algorithm can achieve up to 20% improvement of energy saving comparing with existed methods.

The Implementation of Top Down Approach Method on Redesign of LAN Harvani Hotel Palembang

In this research, the object was taken from one of the hotels in Palembang, namely Harvani Hotel Palembang. This hotel is one of the hotels in South Sumatra Province, where this hotel has 4 floors. Harvani Hotel Palembang has a Local Area Network (LAN) which consists of several computers where LAN is very important to be applied to Harvani Hotel Palembang in order to support administrative work processes (management of hotel data, employee data, guest data to financial data) and guest needs (internet usage in every room of the Hotel which is one of the services provided by Harvani Hotel Palembang). However, the LAN owned by the Harvani Hotel Palembang still has disadvantages, such as LAN still cannot reach every hotel room on the 2nd floor. In addition, the administration side also faces obstacles because each floor of the Harvani Hotel Palembang has its own administrative section and then at the end of each work shift, reports from each administrative section are submitted to the administrative department on the 1st floor using external storage media. Therefore, it is necessary to redesign the Harvani Hotel Palembang LAN by applying the Top Down Approach Method. The results of LAN redesign in this research will be displayed using Cisco Packet Tracer simulator software, where from the simulation results it can be seen that the new design of the Harvani LAN Hotel Palembang has connected the entire computer of each room and every floor of the Hotel. Therefore, if the results of this simulation are applied to Harvani Hotel Palembang, then the administrative work process can be managed directly directly because all data has been stored on the database server. In addition, this new LAN design has also reached all guest rooms of Harvani Hotel Palembang, so guests can access the internet in their respective rooms more comfortably

Hybrid multicriteria algorithms applied to structural design of wireless local area networks

This manuscript presents a novel approach based on hybrid optimization techniques for planning Wireless Local Area Networks in two stages: i) network structure design for access point (AP) placement and channel assignment and ii) channel assignment enhancement. We consider two objective functions: network load balance and signal-to-interference-plus-noise ratio; and three hard constraints: maximum AP capacities, client demand attendance, and minimum coverage levels. The proposed algorithm delivers an approximation of the efficient solution set, considering the two functions described above. The results from two scenarios were compared to the following four approaches: two multiobjective evolutionary algorithms, a well-known commercial tool, and a greedy technique. Finally, the solutions were subjected to sensitivity analysis to validate their robustness regarding user mobility and AP failures.

Green Design of Wireless Local Area Networks by Multiband Robust Optimization

We consider the problem of designing a wireless local area network according to a green paradigm, i.e. serving users with a telecommunication service while minimizing power consumption. To protect against fluctuations in data rate transmission that naturally affect the problem, because of unpredictable user mobility and wireless propagation conditions, we propose a new Multiband Robust Optimization model, and assess its performance on realistic network instances. The preliminary computational experience confirms the effectiveness of the new model in terms of power savings and resiliency against large variations of mobile user positions.

The study of access point outdoor coverage deployment for wireless digital campus network

Wireless local area network design needs more development to obtain appropriate and effective results. Site surveys in the design process give realistic results, but require time and effort. Developing ways of predicting signal strength using empirical models can give appropriate results in access point placement to get good signal coverage. Geospatial analysis, such as inverse distance weighting, Kriging and global polynomial interpolation, has been compared. This study showed that Kriging analysis is an appropriate method to predict value the coverage area. Furthermore, predictive signal strength models such as classical, empirical and COST 231 Hatta models have been studied. The empirical model was shown to do the best predictive calculations. The empirical model used to predict signal strength combined with Kriging geographical statistical analysis gave usable signal coverage prediction for access point placement. This model will support GIS spatial analysis tools to perform effective planning in access point placement.
