Available in PDF, EPUB and Kindle. Book excerpt: The past decade has witnessed a remarkable interest in wireless ad hoc networks that operate without any infrastructure support. The potential for deployment of such networks exists in many scenarios ranging from civil and construction engineering, disaster relief to sensor networks and military applications. The IEEE 802.11 Distributed Coordination Function (DCF) is the dominant MAC (layer) protocol for wireless ad hoc networks. Though the DCF scheme has survived the test of time, it still has its characteristic flaws namely the hidden and exposed terminal problems. Various protocols have been suggested to address these problems thereby leading to an overall increase in network throughput. Some of the popular protocols involve adjusting the carrier sensing threshold, replacing the omni directional antennas with directional antennas and intelligent calibration of transmission power. Studies have shown that directional antennas offer numerous advantages over omni directional antennas and thus has the potential to enhance the performance of ad hoc networks. For one, directional antennas have the ability to streamline their power in the direction of the receiver thereby offering longer transmission and reception ranges for the same amount of power. MAC layer protocols specifically designed to support such directional transmission and reception has been a current active area of research. Most of these protocols consider directional transmission under the assumption that the communication range of omni and directional antennas are the same. Apparently this assumption is not supported in any realistic situation. Moreover, the scientific community has not researched in depth the effect of topology on power consumption in ad hoc networks. In this thesis, we propose a cross-layer power optimization scheme for wireless ad hoc networks. The novelty of our work lies in the fact that we exploit the knowledge of the network topology to dynamically calibrate transmission power. The information about the network topology is retrieved from the Network Layer. Specifically, we consider three different network topologies -- (i) a sparse topology, (ii) a dense topology and a (iii) clusterbased topology. The MAC layer implements a dynamic power control scheme which regulates the transmission power of a transmitting node based on the node density at the receiver's end. In addition a transmitting node can adjust its own transmission power to the optimal level if the SINR value at the receiving node is known. Our cross-layer power control algorithm takes the above fact into account. Extensive simulation in NS2 shows that in all the three topologies our cross layer power control scheme (use of directional antennas with power control) leads to prolonged network lifetime and significantly increases the system throughput.

Available in PDF, EPUB and Kindle. Book excerpt: Ad hoc and ubiquitous computing technologies have received extensive attention in both the academia and industry with the explosive growth of wireless communication devices. These technologies are beneficial for many applications, such as offering futuristic high bandwidth access for users, and are expected to offer more exciting and efficient services, anytime and anywhere. In order to satisfy these diverse applications, the design issues of various wireless networks such as ad hoc, sensor, and mesh networks are extremely complicated and there are a number of technique challenges that need to be explored, involving every layer of the OSI protocol stack. This book aims to provide a complete understanding of these networks by investigating the evolution of ad hoc, sensor, and mesh networking technologies from theoretic concept to implementation protocols, from fundamentals to real applications. It provides the necessary background material needed to go deeper into the subject and explore the research literature. The explanation in the book is therefore sufficiently detailed to serve as a comprehensive reference for students, instructors, researchers, engineers, and other professionals, building their understanding of these networks.

The Dynamic Directional Power Control Protocol (DDPC) is a protocol that dynamically varies the energy used in directional transmission to increase the battery life of the transmitter without sacrificing connectivity with the receiver. The advantage of DDPC is that it takes into account the remaining battery power of a node before changing its transmission power. DDPC can achieve a higher network lifetime when compared to a network where nodes use a fixed transmit power level. Meanwhile DDPC dynamically reduces the energy consumed by a node in transmission. It can also reach nodes far from the transmitter by using directional antennas.

Book excerpt: Following the pattern of the Internet growth in popularity, started in the early 1990s, the current unprecedented expansion of wireless technology promises to have an even greater effect on how people communicate and interact, with considerable socio-economic impact all over the world. The driving force behind this growth is the remarkable progress in component miniaturization, integration, and also devel- ments in waveforms, coding, and communication protocols. Besides established infrastructurebased wireless networks (cellular, WLAN, sat- lite) ad-hoc wireless networks emerge as a new platform for distributed applications and for personal communication in scenarios where deploying infrastructure is not feasible. In ad-hoc wireless networks, each node is capable of forwarding packets on behalf of other nodes, so that multi-hop paths provide end-to-end connectivity. The increased flexibility and mobility of ad-hoc wireless networks are favored for appli- tions in law enforcement, homeland defense and military. In a world where wireless networks become increasingly interoperable with each other and with the high-speed wired Internet, personal communication systems will transform into universal terminals with instant access to variate content and able of handle demanding tasks, such as multimedia and real-time video. With users roaming between networks, and with wide variation in wireless link quality even in a single domain, the communications terminal must continue to provide a level of Quality of Service that is acceptable to the user and conforms to a contracted Service Level Agreement.

Available in PDF, EPUB and Kindle. Book excerpt: Au cours de la dernière décennie, un intérêt remarquable a été éprouvé en matière des réseaux ad hoc sans fil capables de s'organiser sans soutien des infrastructures. L'utilisation potentielle d'un tel réseau existe dans de nombreux scénarios, qui vont du génie civil et secours en cas de catastrophes aux réseaux de capteurs et applications militaires. La Fonction de coordination distribuée (DCF) du standard IEEE 802.11 est le protocole dominant des réseaux ad hoc sans fil. Cependant, la méthode DCF n'aide pas à profiter efficacement du canal partagé et éprouve de divers problèmes tels que le problème de terminal exposé et de terminal caché. Par conséquent, au cours des dernières années, de différentes méthodes ont été développées en vue de régler ces problèmes, ce qui a entraîné la croissance de débits d'ensemble des réseaux. Ces méthodes englobent essentiellement la mise au point de seuil de détecteur de porteuse, le remplacement des antennes omnidirectionnelles par des antennes directionnelles et le contrôle de puissance pour émettre des paquets adéquatement. Comparées avec les antennes omnidirectionnelles, les antennes directionnelles ont de nombreux avantages et peuvent améliorer la performance des réseaux ad hoc. Ces antennes ne fixent leurs énergies qu'envers la direction cible et ont une portée d'émission et de réception plus large avec la même somme de puissance. Cette particularité peut être exploitée pour ajuster la puissance d'un transmetteur en cas d'utilisation d'une antenne directionnelle. Certains protocoles de contrôle de puissance directionnel MAC ont été proposés dans les documentations. La majorité de ces suggestions prennent seulement la transmission directionnelle en considération et, dans leurs résultats de simulation, ces études ont l'habitude de supposer que la portée de transmission des antennes omnidirectionnelles et directionnelles est la même. Apparemment, cette supposition n'est pas toujours vraie dans les situations réelles. De surcroî
