Reinforcement of trust in DSR

In mobile ad hoc networks (MANETs), nodes have to cooperate in order to accomplish routing tasks. Nevertheless, they are generally composed of limited resources and may behave in a selfish way. In this paper, we propose a trust model for reactive routing in MANETs. The proposed solution is founded on a mechanism inspired by the CONFIDANT protocol to install and update trust in the network. It fits topology changes caused by the mobility of nodes. In addition, it takes into account new routes learned after the route request phase. It finally, improves the choice of the safest route towards the destination.
