Sensor networks consist of large number of nodes with limited energy, computation and transmission power. Each node in the network helps every other node by forwarding their packets to reach the destination .Since these nodes operate in a physically insecure environment; they are vulnerable to different types of attacks such as sinkhole and wormhole. These attacks can inject malicious packets by compromising the node. Conventional routing protocols have been developed without considering the security aspects against these attacks. In this paper, a secure routing protocol named secured dynamic source routing protocol(S-DSR) is proposed for mobile sensor networks by incorporating trust based mechanism in the existing dynamic source routing protocol (DSR). Simulation results prove that S-DSR outperforms the DSR by reducing the packet drop, delay and improving the delivery ratio of the networks.
