Download or read book Modeling and Analysis of the Performance of Collaborative Wireless Ad hoc Networks written by Ramanan Subramanian and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work focuses on the performance characterization of distributed collaborative ad-hoc networks, focusing on such metrics as the lifetime, latency, and throughput capacity of two such classes of networks. The first part concerns modeling and optimization of static Wireless Sensor Networks, specifically dealing with the issues of energy efficiency, lifetime, and latency. We analyze and characterize these performance measures and discuss various fundamental design tradeoffs. For example, energy efficiency in wireless sensor networks can only be improved at the cost of the latency (the delay incurred during communication). It has been clearly shown that improvement in energy efficiency through data aggregation increases the latency in the network. In addition, sleep-active duty cycling of nodes (devices constituting the network), a commonly employed mechanism to conserve battery lifetime in such networks, has adverse effects on their functionality and capacity. Hence these issues deserve a detailed study.

Download or read book Performance Analysis and Optimization of Infrastructure Aerial and Multi hop Ad hoc Networks written by Nadir Hussin Sulieman Adam and published by . This book was released on 2020 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: "With the increasing availability of wireless networks, the continuous development of new wireless technologies and recent technological advancements in the area of unmanned aerial systems, it is essential to optimize the users' connection to meet the increased demands in terms of throughput and delay. In conventional infrastructure-based networks, the devices are connected to a central entity that is responsible for coordinating the network. Although infrastructure networks may be available in many situations, infrastructure-less or ad-hoc networks are necessary in situations where infrastructure-based networks are difficult to deploy (e.g., disaster or rural areas) or are inefficient to support connectivity. Therefore analyzing, optimizing, and selecting the best connection, whether it is through an existing infrastructure or an ad-hoc network, is vital for optimizing the users' performance and meeting the quality of service (QoS) requirements. My dissertation examines various approaches to optimize network connectivity for both wireless sensor networks and for mobile users. For example, I have used real elephants' movement data and a multi-sink extension to the epidemic routing with vaccine protocol in Network Simulator (ns-3) to analyze the performance ofWi-Fi infrastructure mode and multi-hopWi-Fi ad-hoc mode in a real life animal tracking sensor network application called JumboNet. Based on simulation results, Wi-Fi adhoc mode with epidemic routing outperforms infrastructure mode Wi-Fi in terms of packet delivery ratio. On the other handWi-Fi in infrastructure mode results in a lower delay and energy consumption per packet with the cost of a lower number of delivered packets. Additionally, I developed an Android application that scans and collects information about the accessibility, quality and attributes of Wi-Fi access points, and cellular base stations. Moreover, the application measures the throughput and delay of the infrastructure networks. Based on the collected data, about 10% of the scanned locations have only 0-2 Wi-Fi access points (APs), and for more than 20% of the locations, all the available APs are private and inaccessible due to security restrictions. Using an ad-hoc network can allow devices that do not have a direct access to the infrastructure network to be connected through other devices that do have access to the Wi-Fi APs. In this regard, I developed an Android application that connects a Wi-Fi Direct ad-hoc network to the Internet via a gateway node that is connected to an infrastructure network. The application can be used to evaluate the impact of extending access to the Internet to devices that do not have direct access. Moreover, based on energy consumption models for LTE, Wi-Fi and Wi-Fi Direct, I evaluated the tradeoffs between throughput, delay, and energy consumption of infrastructure and multi-hop ad-hoc networks. Based on the collected data, the throughput of infrastructure and multihop ad-hoc networks increases with increasing data size. Furthermore,Wi-Fi Direct multi-hop ad-hoc networks withWi-Fi connection from the gateway node are more energy efficient when uploading and downloading data compared with a direct cellular connection in some cases. Furthermore, I investigated the 3D placement problem for multiple unmanned aerial vehicles base stations (UAV-BSs) that maximizes the number of covered users with the same as well as with different QoS requirements. First, I presented a mathematical formulation of the multiple UAV-BSs placement problem, and showed that it is a non-convex optimization problem. Then, I proposed two heuristic algorithms, and I showed that for users with the same as well as with different QoS requirements, the proposed algorithms achieve near optimal performance and outperform the Linear Approximation (LA) state-of-the-art algorithm in terms of the average number of covered users and execution time. Finally, I explored the 3D placement problem for multiple UAV-BSs that maximizes the number of covered ground users both with and without support of multi-hop ad hoc ground networks. First, I presented a mathematical formulation of the single UAV-BS placement problem, then I proposed a heuristic algorithm that maximizes the number of directly and indirectly covered ground users considering users with the same as well as with different quality of service (QoS) requirements. Simulation results show the merits of utilizing the multi-hop capabilities of the ground users in terms of reducing the number of UAV-BSs required to cover the users. Overall, this dissertation contributes to the design, analysis, and optimization of infrastructurebased, aerial and multi-hop ad-hoc networks in various applications ranging from WSNs to mobile networks. Furthermore, these contributions will give new insights to the design of next generation wireless networks that are able to meet the users' demands and QoS requirements."--Pages x-xii.

This book was released on 2005-08-05 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topology control is fundamental to solving scalability and capacity problems in large-scale wireless ad hoc and sensor networks. Forthcoming wireless multi-hop networks such as ad hoc and sensor networks will allow network nodes to control the communication topology by choosing their transmitting ranges. Briefly, topology control (TC) is the art of co-ordinating nodes’ decisions regarding their transmitting ranges, to generate a network with the desired features. Building an optimized network topology helps surpass the prevalent scalability and capacity problems. Topology Control in Wireless Ad Hoc and Sensor Networks makes the case for topology control and provides an exhaustive coverage of TC techniques in wireless ad hoc and sensor networks, considering both stationary networks, to which most of the existing solutions are tailored, and mobile networks. The author introduces a new taxonomy of topology control and gives a full explication of the applications and challenges of this important topic. Topology Control in Wireless Ad Hoc and Sensor Networks: Defines topology control and explains its necessity, considering both stationary and mobile networks. Describes the most representative TC protocols and their performance. Covers the critical transmitting range for stationary and mobile networks, topology optimization problems such as energy efficiency, and distributed topology control. Discusses implementation and ‘open issues’, including realistic models and the effect of multi-hop data traffic. Presents a case study on routing protocol design, to demonstrate how TC can ease the design of cooperative routing protocols. This invaluable text will provide graduate students in Computer Science, Electrical and Computer Engineering, Applied Mathematics and Physics, researchers in the field of ad hoc networking, and professionals in wireless telecoms as well as networking system developers with a single reference resource on topology control.

Download or read book Mobile Wireless and Sensor Networks written by Amine Dahane and published by CRC Press. This book was released on 2019-07-01 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless networking covers a variety of topics involving many challenges. The main concern of clustering approaches for mobile wireless sensor networks (WSNs) is to prolong the battery life of the individual sensors and the network lifetime. For a successful clustering approach, the need of a powerful mechanism to safely elect a cluster head remains a challenging task in many research works that take into account the mobility of the network. In Mobile, Wireless and Sensor Networks: A Clustering Algorithm for Energy Efficiency and Safety, the authors use an approach based on computing of the weight of each node in the network as the proposed technique to deal with this problem. They present a virtual laboratory platform (VLP) of baptized mercury, allowing students and researchers to make practical work (PW) on different aspects of mobile wireless sensor networks. The authors’ choice of WSNs is motivated mainly by the use of real experiments needed in most college courses on WSNs. These usual experiments, however, require an expensive investment and many nodes in the classroom. The platform presented here aims at showing the feasibility, the flexibility, and the reduced cost using the authors’ approach. The authors demonstrate the performance of the proposed algorithms that contribute to the familiarization of the learners in the field of WSNs. The book will be a valuable resource for students in networking studies as well as for faculty and researchers in this area.

Download or read book Traffic Based Energy Consumption Optimisation to Improve the Lifetime and Performance of Ad Hoc Wireless Sensor Networks written by Qasim Iqbal and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ad hoc wireless sensor networks (WSNs) are formed from self-organising configurations of distributed, energy constrained, autonomous sensor nodes. The service lifetime of such sensor nodes depends on the power supply and the energy consumption, which is typically dominated by the communication subsystem. One of the key challenges in unlocking the potential of such data gathering sensor networks is conserving energy so as to maximize their post deployment active lifetime This thesis described the research carried on the continual development of the novel energy efficient Optimised grids algorithm that increases the WSNs lifetime and improves on the QoS parameters yielding higher throughput, lower latency and jitter for next generation of WSNs. Based on the range and traffic relationship the novel Optimised grids algorithm provides a robust traffic dependent energy efficient grid size that minimises the cluster head energy consumption in each grid and balances the energy use throughout the network. Efficient spatial reusability allows the novel Optimised grids algorithm improves on network QoS parameters. The most important advantage of this model is that it can be applied to all one and two dimensional traffic scenarios where the traffic load may fluctuate due to sensor activities. During traffic fluctuations the novel Optimised grids algorithm can be used to re-optimise the wireless sensor network to bring further benefits in energy reduction and improvement in QoS parameters. As the idle energy becomes dominant at lower traffic loads, the new Sleep Optimised grids model incorporates the sleep energy and idle energy duty cycles that can be implemented to achieve further network lifetime gains in all wireless sensor network models. Another key advantage of the novel Optimised grids algorithm is that it can be implemented with existing energy saving protocols like GAF, LEACH, SMAC and TMAC to further enhance the network lifetimes and improve on QoS parameters. The novel Optimised grids algorithm does not interfere with these protocols, but creates an overlay to optimise the grids sizes and hence transmission range of wireless sensor nodes.
