The DSR protocol is frequently used to establish communication in mobile ad-hoc wireless networks. For effective functioning of the protocol it is essential that no malicious nodes should participate in its execution. In this paper, we present a novel scheme for identifying and isolating malicious nodes in a DSR based network. We make use of special trust filters that are implemented and executed by the benevolent nodes. Through extensive simulations, we demonstrate that the filtered DSR protocol augments the performance of the standard DSR protocol by up to 30% in a network where 40% of the nodes act maliciously.
