Truthful Detection Of Selfish Nodes In Context To Replica Allocation Over A Mobile Ad Hoc Network

Mobile ad-hoc network (MANET) is a network that allows mobile servers and clients to communicate in the absence of fixed infrastructure. MANET is a fast growing area of research as it finds uses in variety of applications. In order to facilitate efficient data access and update databases are deployed on MANET. Since data accessibility is affected by the mobility and power constraints of the servers and clients, data in MANET are replicated. As in ad-hoc network, since mobile host move freely network partition occurs frequently thus data availability is reduced resulting in performance degradation. Most of the replication techniques assume that every node forwards every packet given to it and collaborate fully in terms of sharing the memory space. But in practice some of the nodes may act as selfish nodes which may selfishly decide whether to cooperate partially or not cooperate at all with the other nodes. Thus, selfish behavior of nodes could reduce the overall data accessibility in the network. The concept of the paper deals with truthful detection of selfish nodes i.e. some nodes may give false alarm as differentiated from overall selfishness alarm and to inform the other nodes at route as exactly where the disconnections occur to select the next best alternative path and also to increase the performance with increased congestion control. Detection of attacker node in the network and should be informed to all others in the network
