Download or read book Energy Efficient Cooperative Wireless Communication and Networks written by Zhengguo Sheng and published by CRC Press. This book was released on 2014-11-11 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared with conventional communications, cooperative communication allows multiple users in a wireless network to coordinate their packet transmissions and share each other's resources, thus achieving high-performance gain and better service coverage and reliability. Energy Efficient Cooperative Wireless Communication and Networks provides a comprehensive look at energy efficiency and system design of cooperative wireless communication. Introducing effective cooperative wireless communication schemes, the book supplies the understanding and methods required to improve energy efficiency, reliability, and end-to-end protocol designs for wireless communication systems. It explains the practical benefits and limitations of cooperative transmissions along with the associated designs of upper-layer protocols, including MAC, routing, and transport protocol. The book considers power efficiency as a main objective in cooperative communication to ensure quality-of-service (QoS) requirements. It explains how to bring the performance gain at the physical layer up to the network layer and how to allocate network resources dynamically through MAC/scheduling and routing to trade off the performance benefits of given transmissions against network costs. Because the techniques detailed in each chapter can help readers achieve energy efficiency and reliability in wireless networks, they have the potential to impact a range of industry areas, including wireless communication, wireless sensor networks, and ad hoc networks. The book includes numerous examples, best practices, and models that capture key issues in real-world applications. Along with algorithms and tips for effective design, the book supplies the understanding you will need to achieve high-performing and energy efficient wireless networks with improved service coverage and reliability.
Download or read book Cross layer Aware Transport Protocols for Wireless Networks written by and published by . This book was released on 2007 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation addresses the problem of reliable file transfer over single-hop and multi-hop shared-media wireless networks which are generally characterized by fluctuating bandwidth and error characteristics. Traditional reliable file transport protocols such as TCP assume relatively slow-varying links and were not generally designed to deal with interference problems of shared media wireless networks. The large performance gap between unreliable UDP and reliable TCP motivates the investigation of new transport protocols that might achieve significantly faster file transfer than TCP on wireless media. CLAP - a Cross Layer Aware transport Protocol has been developed as a general solution for reliable file transfer, with decoupled flow control and error control to accommodate time-varying links. Error control in CLAP was designed to minimize interference and round-trip time estimation. Flow control in the proposed transport protocol leverages MAC status information via a novel cross-layer software framework (CLF), developed to provide systematic access to intra-node and inter-node status information. Single hop evaluations, which consider an 802.11b wireless LAN with wired backhaul, were carried out using both NS2 simulations and ORBIT test-bed experiments. In time-varying, high loss scenarios, TCP shuts down operation without MAC retries, while an early CLAP version (CLAP-beta) achieves over 68% of upper-bound UDP performance. In noise-free scenarios, a "skip-ACKs" TCP modification to reduce interference achieves limited gains since TCP flow control depends on regular ACKs, while CLAP-beta approaches peak UDP performance by fully using the bandwidth available. Multi-hop evaluations with NS2 simulations consider a 3-hop primary path in a 4x4 wireless mesh over 802.11b single-channel interfaces. Occasional background flows and on-off channel noise injection produce bandwidth and error fluctuations. These simulations expose the general multi-hop wireless problem where self interference in the forward path significantly reduces end-to-end bandwidth. Increasing interference and random packet losses tend to degrade TCP performance even more significantly than in 1-hop scenarios. Here, CLAP-final with improvements (relative to CLAP-beta) to reduce dependence on RTT estimation achieves over 90% of UDP performance in a variety of time-varying conditions. This thesis demonstrates the efficacy of reliable file transfer using CLAP to address interference and time-varying links in both single- and multi-hop wireless network scenarios. Future research opportunities include cross-layer techniques for error control, efficient inter-node protocols for CLF, and tighter integration with mesh network routing protocols.

Download or read book Mobile and Wireless Communications Networks written by Elizabeth M. Belding-Royer and published by Springer. This book was released on 2006-08-17 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile Ad hoc NETworks (MANETs) has attracted great research interest in recent years. A Mobile Ad Hoc Network is a self-organizing multi-hop wireless network where all hosts (often called nodes) participate in the routing and data forwarding process. The dependence on nodes to relay data packets for others makes mobile ad hoc networks extremely susceptible to various malicious and selfish behaviors. This point is largely overlooked during the early stage of MANET research. Many works simply assume nodes are inherently cooperative and benign. However, experiences from the wired world manifest that the reverse is usually true; and many works [3] [10] [9] [8] [12] [19] have pointed out that the impact of malicious and selfish users must be carefully investigated. The goal of this research is to address the cooperation problem and related security issues in wireless ad hoc networks. As a rule of thumb, it is more desirable to include security mechanisms in the design phase rather than continually patching the system for security breaches. As pointed out in [2] [1], there can be both selfish and malicious nodes in a mobile ad hoc network. Selfish nodes are most concerned about their energy consumption and intentionally drop packets to save power. The purpose of malicious nodes, on the other hand, is to attack the network using various intrusive techniques. In general, nodes in an ad hoc network can exhibit Byzantine behaviors.

Download or read book Protocols for Packet Switched Communication and Reliable Multicasting in Fully dynamic Multi hop Wireless Networks written by James Pelech and published by . This book was released on 1998 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing protocols for a fully dynamic wireless packet switched networks pose unique challenges due to the constantly changing topology of the network. A set of protocols is presented that are capable of handling a fully dynamic wireless network in which switching centers and base stations are mobile as well as the end users. The protocols provide basic message delivery, network routing information updates, and support for reliable multicasting. There are four contributions of this work: (i) a hierarchical architecture for a fully dynamic wireless network, (ii) improved routing and update protocols with reduced control traffic, (iii) a method to provide reliable multicasting in a wireless environment that is near optimal in terms of the number of messages sent, and (iv) a set of load balancing algorithms that allow the network to autonomously and dynamically reconfigure the network topology to even out the load on the base stations. A detailed simulation of the protocols is developed and exercised to evaluate the performance of the protocols. For point to point delivery, the protocols successfully deliver all packets even when the rate of motion of the terminals causes more than 1/2 of them to be in a transitional state at any time. The results are similar for base station.
