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.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we study multi-hop versions of two classes of wireless networks: (a) Mobile Ad HocNetworks (MANETs) and (b) Wireless Mesh Networks (WMNs). Our primary focus is to developreliable structures for MANETs and energy-efficient implementations for WMNs.We study a MANET setting where each node in the MANET engages in deliberate and discreetpacket-dropping at a certain rate, while relaying on behalf of other nodes. Assuming the nodesto be non-cooperative, we develop a scheme in which each source node would blame its nearestneighbor for any packet dropped along the multi-hop path vector. This is simple, but elegant, asit still reveals the true relative dropping rates of each packet-dropping node in the MANET.We then propose a novel scheme for improving the overall performance or robustness of such aMANET by adopting a routing strategy which considers the recent packet-dropping performance(reputation) of intermediate relaying nodes in determining the best route from a source to a destination.For deciding the best route, we propose the use of mechanisms based on the modification of theAd Hoc On-Demand Distance Vector (AODV) routing protocol. As opposed to the AODV scheme,which uses a broadcast mechanism for route discovery, the proposed scheme (called Robust AODVor RAODV) considers the reputation levels of neighboring nodes to determine the node(s) to whichthe route discovery packet should be sent.In connection with WMNs, we study a WMN structure deployed for residential broadband Internet access and WMN applications for Wireless Sensor Networks (WSNs).Our WMN model deployed for residential broadband Internet access has a specific topology ofthree tiers comprising WMN infrastructure nodes or Mesh Access Points (MAPs), fixed, in-rangeend-users or end-user Stations (STAs), and potentially mobile, out-of-range end-users or Mobile-STAs (M-STAs). Our interest is only at the edge as our primary focus is the range extension of the WMN to M-STAs via the relaying services of STAs. We develop an iterative game model in whichthe relaying STAs engage in deliberate packet-dropping of M-STA packets for their own throughputgain.We next extend the model to include the scenario in which the MAP and the STAs are networkservice providers in respectively a primary and a secondary market. The STAs do not engage indeliberate packet-dropping, since they are now wholly responsible for providing traffic to the M-STAs, and as a result will lose revenue. Obviously, the second model is better for mobile end-users(M-STAs) as they receive better service since STAs do not drop packets in this scenario for theirown selfish reasons.We then investigate WMNs used in Advanced Metering Infrastructure (AMI), which is a formof WSN. These WMNs usually consist of a collection of Neighborhood Area Networks (NANs),which include smart, wireless-enabled meters or sensor nodes.We present an elegant approach to reducing the cost of the AMIs by increasing the ratio of thenumber of sensors/meters in Neighborhood Area Networks (NANs) to the number of Access Points(APs) or gateways.Finally, we propose schemes for energy conservation in Industrial Wireless Sensor Networks(IWSNs), which are variants of WMNs. Our contribution integrates new approaches to partitioning an IWSN into energy-efficient clusters with a graph-theoretical framework for energy-efficient routing within a cluster. The concept of betweenness centrality is demonstrated to be a useful metric to optimize the placement of the cluster head within an IWSN cluster in our clustering approach.In addition, our strategy combines a novel scheme for duty cycling of the nodes in a cluster tofurther minimize energy expenditure in an IWSN. Betweenness centrality is also used as a metricfor developing a duty-cycling approach to further minimize the energy consumption in an IWSN.Most of the previous contributions have dealt with only one particular approach to minimizingenergy consumption in an IWSN. The emphasis in some of them has been on efficient partitioningof the IWSN into clusters, while others have dealt with energy-efficient routing or effective approachto duty cycling of sensor nodes.In contrast, this contribution integrates a new graph-theoretical framework for partitioning anIWSN into energy-efficient clusters, a minimum-cost (i.e., energy-efficient) routing scheme withina cluster, and a novel duty-cycling scheme to further minimize the cluster's energy consumption.

This book was released on 2012 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable multi-hop packet forwarding is an important requirement for the implementation of realistic large-scale wireless ad-hoc networks. However, packet forwarding methods based on a single criterion, such as the traditional greedy geographic forwarding, are not sufficient in most realistic wireless settings because perfect-reception-within-rangecannot be assumed. Furthermore, methods where the selection of intermediate relaying nodes is performed at the transmitter-side do not adapt well to rapidly changing network environments. Although a few link-aware geographic forwarding schemes have been reported in the literature, the tradeoffs between multiple decision criteria and their impact on network metrics such as throughput, delay and energy consumption have not been studied. This dissertation presents a series of strategies aimed at addressing the challenges faced by the choice of relay nodes in error-prone dynamic wireless network environments. First, a single-criterion receiver-side relay election (RSRE) is introduced as a distributed alternative to the traditional transmitter-side relay selection. Contrary to the transmitter- side selection, at each hop, an optimal node is elected among receivers to relay packets toward the destination. Next, a multi-criteria RSRE, which factors multiple decision criteria in the election process at lower overhead cost, is proposed. A general cost metric in the form of a multi-parameter mapping function aggregates decision criteria into a single metric used to rank potential relay candidates. A two-criteria RSRE case study shows that a proper combination of greedy forwarding and link quality leads to higher energy efficiency and substantial improvement in the end-to-end delay. Last, mesh multi-path forwarding methods are examined. A generalized mesh construction algorithm in introduced to show impact of a mesh structure on network performance.

This book was released on 2020-01-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on core functionalities for wireless real-time multi-hop networking with TDMA (time-division multiple access) and their integration into a flexible, versatile, fully operational, self-contained communication system. The use of wireless real-time communication technologies for the flexible networking of sensors, actuators, and controllers is a crucial building block for future production and control systems. WirelessHART and ISA 100.11a, two technologies that have been developed predominantly for industrial use, are currently available. However, a closer analysis of these approaches reveals certain deficits. Current research on wireless real-time communication systems shows potential to remove these limitations, resulting in flexible, versatile, and robust solutions that can be implemented on today’s low-cost and resource-constrained hardware platforms. Unlike other books on wireless communication, this book presents protocols located on MAC layer and above, and build on the physical (PHY) layer of standard wireless communication technologies.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation we focus on design and analysis of an integrated architecture for useful and efficient multihop wireless networks (MWNs). We first concentrate on development of on-demand medium access control (MAC) protocols for the network and cross layer optimizations to improve network performance using multiple beam antennas. We show the inherent inability of predominantly used MAC protocols to fully exploit the benefits of multiple beam antenna arrays and demonstrate the superiority of our protocols. We also present our receiver oriented MAC protocol to provide differentiated service classes on these antenna systems, the first successful attempt to achieve this goal. We next look at the security of communication over multihop wireless networks. In this section we also provide a highly scalable and completely distributed protocol to generate symmetric group communication keys. We then move on to queueing analysis of multihop wireless networks which cannot be quantified using classical queueing theory. We present our theory of Exclusive Access Queues (EAQs) and show how to apply them to MWNs. Finally, we present the design of the wireless device driver we implemented to run our protocols on wireless devices. We show the architecture best suited for the requirements of our protocols and the inter-operation between various driver entities.
