Book excerpt: We present the hybrid activation multiple access (HAMA) protocol for ad hoc networks. Unlike previous channel access scheduling protocols that activate either nodes or links only, HAMA is a node-activation channel access protocol that also maximizes the chance of link activations using time- and code-division schemes. HAMA only requires identifiers of the neighbors within two hops from each node to schedule channel access. Using this neighborhood information, each node determines whether to transmit in the current time slot on a dynamically assigned spreading code. A neighbor protocol supplements HAMA with up-to-date two-hop neighborhood information by reliably propagating the one-hop neighbor updates through a novel random access technique. The throughput and delay characteristics of HAMA in randomly-generated multihop wireless networks are studied by analyses and simulations. The results of the analyses show that HAMA achieves higher channel utilization in ad hoc networks than a distributed scheduling scheme based on node activation, similar throughout as a well-known scheduling algorithm based on complete topology information, and much higher throughout than the ideal CSMA and CSMA/CA protocols.

Available in PDF, EPUB and Kindle. Book excerpt: A new family of collision-free channel access protocols for ad hoc networks with unidirectional links is introduced. These protocols are based on a distributed contention resolution algorithm that operates at each node based on the list of direct contenders (one-hop neighbors or incident links) and indirect interferences (two-hop neighbors and related links). Depending on the activation scheme (node activation or link activation), a network node uses the identifiers of its neighbors one and two hops away to elect deterministically one or multiple winners for channel access in each contention context (e.g., a time slot or a frequency band). The protocols are shown to be fair and capable of achieving maximum utilization of the channel bandwidth. The delay and throughput characteristics of the channel access protocols is studied by simulations.

Download or read book Neighbor-Aware Control in Ad Hoc Networks written by Lichun Bao and published by LAP Lambert Academic Publishing. This book was released on 2010-03 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical ad hoc networks have unique challenges, such as constant network topology changes, bandwidth-constrained connections and diverse wireless signal fading scenarios. This book presents the design and evaluation of novel and efficient control mechanisms for channel access scheduling and topology control functions in ad hoc networks. The work is based on the neighbor-aware contention resolution (NCR) algorithm, which use only local neighborhood information to achieve globally consistent decisions, thus applicable to solve various control problems in ad hoc networks that required high control overhead before. First, channel access protocols based on NCR are presented for ad hoc networks with omni-directional antennas, namely NAMA, LAMA, PAMA and HAMA, which correspond to node-, link-, pair-wise- and hybrid-activation multiple access protocols, respectively. Furthermore, the collision-free channel access functions for ad hoc networks that have unidirectional links or directional antennas are presented, which were difficult if not impossible to achieve without NCR. NCR-based topology management that constructs a backbone structure in ad hoc networks is presented as well.

Available in PDF, EPUB and Kindle. Book excerpt: This second book by the author on WSNs focuses on the concepts of energy, and energy harvesting and management techniques. Definitions and terminologies are made clear without leaning on the relaxing assumption that they are already known or easily reachable, the reader is not to be diverted from the main course. Neatly drawn figures assist in viewing and imagining the offered topics. To make energy related topics felt and seen, the adopted technologies as well as their manufacturers are presented in details. With such a depth, this book is intended for a wide audience, it is meant to be helper and motivator, for the senior undergraduates, postgraduates, researchers, and practitioners; concepts and energy related applications are laid out, research and practical issues are backed by appropriate literature, and new trends are put under focus. For senior undergraduate students, it familiarizes with conceptual foundations and practical projects implementations. Also, it is intended for graduate students working on their thesis and in need of specific knowledge on WSNs and the related energy harvesting and management techniques. Moreover, it is targeting researchers and practitioners interested in features and applications of WSNs, and on the available energy harvesting and management projects and testbeds. Exercises at the end of each chapter are not just questions and answers; they are not limited to recapitulate ideas. Their design objective is not bound to be a methodical review of the provided concepts, but rather as a motivator for lot more of searching, finding, and comparing beyond what has been presented in the book.

Available in PDF, EPUB and Kindle. Book excerpt: A mobile ad hoc network (MANET) is a collection of two or more wireless devices with the capability to communicate with each other without the aid of any centralized administrator. Ad hoc networks have no fixed routers, these nodes can be connected dynamically in an arbitrary manner. MANETs, due to their operational characteristics, the dynamics of their changes and the precariousness of their resources, offer huge challenges due to the architecture and service nature in the next generation of mobile communications. MANETs play an important role in the future of next-generation networks. This special collection identifies and studies the most important concerns in MANETs, and includes contributions from researchers, academics, etc.
