DOWNLOAD EBOOKWireless Mobile Ad-hoc Networks are characterized by dynamic network topology and lack of network infrastructure. The network fragments into smaller networks and merges over a period of time due to mobility. This makes provisioning solutions to common network problems, like routing and QoS provisioning, a challenging task. Services in ad-hoc networks face two-fold problems. Making nodes aware of the availability and the location of services in a dynamically changing network is difficult, especially when such services are not tightly coupled with a fixed infrastructure. Servers may come and leave the network. Nodes may shutdown services to conserve energy. The problem is further exacerbated by the limitations posed by the wireless network on the bandwidth and by the limited computational capability of the wireless devices. This thesis addresses the problem of providing continuous and guaranteed access to such centralized services in a mobile wireless ad-hoc network. A distributed algorithm based on the exchange of service provider information is proposed to solve the problem. The previous work addressing the same problem assumes that the nodes move in long-term groups. Our solution does not make this assumption and targets arbitrary motion. So, no attempt is made to correlate the movement of the nodes, in order to solve the problem. In this thesis, we illustrate that our approach achieves higher service availability than the previous methods at the cost of a higher number of service instances. The proposed algorithm converges after a time period equivalent to the average propagation delay of the service instance information from a service provider to its reachable nodes. The computational and communication complexity of the algorithm is theoretically proved to be O(slogn) and O(n[subscript g]2) where s is the number of service instances, n is the number of nodes in the ad-hoc network and n[subscript g] is the average number of nodes in a connected component of t.

DOWNLOAD EBOOK"This book should be immensely interesting to those trying to decide what MANET research is worth undertaking and why." -J. Christopher Ramming, Program Manager, Defense Advanced Research Projects Agency (DARPA) Strategic Technology Office A thorough, comprehensive treatment of mobile ad hoc network management Mobile ad hoc networking is a hot topic, gaining importance in both commercial and military arenas. Now that the basics in the field have settled and standards are emerging, the time is right for a book on management of these networks. From two experts in the field, Policy-Driven Mobile Ad hoc Network Management provides comprehensive coverage of the management challenges associated with mobile ad hoc networks(MANETs) and includes an in-depth discussion of how policy-based network management can be used for increasing automation in the management of mobile ad hoc networks. This book provides readers with a complete understanding of mobile ad hoc network management and many related topics, including: ?Network management requirements for MANETs, with an emphasis on the differences between the management requirements for MANETs as compared to static, wireline networks ?The use of policies for managing MANETs to increase automation and to tie together management components via policies ?Policy conflict detection and resolution ?Aspects of MANETs that need to be configured and reconfigured at all layers of the protocol stack ?Methodologies for providing survivability in the face of both hard and soft failures in MANETs ?The components of a Quality of Service (QoS) management solution for MANETs based on the widely used Differentiated Services (DiffServ) paradigm ?Important open research issues in the area of MANET management Policy-Driven Mobile Ad hoc Network Management is an ideal resource for professionals, researchers, and advanced graduate students in the field of IP network management who are interested in mobile ad hoc networks.

DOWNLOAD EBOOKThe 8th International Conference on Ad-Hoc Networks and Wireless (ADHOC-NOW 2009) was held September 22–25, 2009 in Murcia, Spain. Since ADHOCNOW started as a workshop in 2002, it has become a well-established and well-known international conference dedicated to wireless and mobile c- puting. During the last few years it has been held in Toronto, Canada (2002), Montreal, Canada (2003), Vancouver, Canada (2004), Cancun, Mexico (2005), Ottawa, Canada (2006), Morelia, Mexico (2007) and Sophia Antipolis, France (2008). The conference serves as a forum for interesting discussions on ongoing research and new contributions addressing both experimental and theoretical research in the area of ad hoc networks, mesh networks, sensor networks and vehicular networks. In 2009, we recived 92 submissions from 28 di?erent countries around the globe: Algeria, Australia, Brazil, Canada, China, Egypt, Finland, France, G- many, Greece, India, Iran, Ireland, Italy, Japan, Korea, Luxembourg, Malaysia, Mexico,Norway,Poland,Portugal,Serbia,SouthAfrica,Spain,Tunisia,UKand USA. Of the submitted papers, we selected 24 full papers and 10 short papers for publication in the proceedings and presentation in the conference.

DOWNLOAD EBOOKIn wireless ad-hoc networks spontaneously formed by mobile nodes, diverse node movements cause the network to partition into completely disconnected subnetworks. The network partitioning poses significant challenges to the provisioning of centralized service in the ad-hoc network, since as the result of partitioning, many mobile nodes become disconnected from the central server. In this thesis, we propose a collection of novel run-time algorithms that adaptively maintain the availability of the centralized service to all mobile nodes while minimizing the service cost incurred. We exploit the mobility pattern exhibited by mobile hosts. In particular, the central server predicts network partitioning using techniques to recognize the mobility pattern and replicate service in advance. The regular mobile nodes judiciously select service based on mobility similarity to adapt to the dynamic network partitionings. Our simulation results show the algorithms proposed can efficiently provide network-wide service accessibility in the frequently partitionable ad-hoc networks.
