Trust Based Routing in DSR over Mobile Ad-hoc Network

M.Tech(CSE), Assistant Professor 1,2 Computer Science and Engineering Department MMEC, Mullana [email protected] [email protected] Abstract: A mobile ad-hoc network is a self-configuring network or infrastructure-less network of mobile nodes connected by wireless links which together form a random topology. Due to absence of centralized control, multihop communications and dynamic network topology, the provision of making routing secure in mobile ad hoc networks is much more challenging than the security in wired network or infrastructure based networks. Nodes in mobile Ad Hoc Network (MANET) do not depend on a central infrastructure but relay packets originated by other mobile nodes. Mobile ad hoc networks can work properly only if the participating nodes cooperate in routing and forwarding. For individual nodes it might be advantageous not to cooperate, though. In this research paper, we propose a new approach based on relationship among the mobile nodes which makes them to cooperate in an infrastructure-less environment. The faith unit is used to calculate the faith values of each node in the network. The calculated faith values are being used by the relationship estimator to determine the relationship status of mobile nodes. The proposed enhanced protocol was compared with the standard DSR protocol and the results are analyzed using the MATLAB-R2008a.
