A Security Routing Protocol of Ad Hoc network based on node trust evalution

The routing protocol is the core of the Ad Hoc network protocols, which largely determines the performance and features of an Ad Hoc network. Aiming at the characteristics of the Mobile Radio Ad Hoc network, this paper is to design a low-rate mobile Ad Hoc network routing protocols WLRP (Wireless Low-Rate Ad Hoc Security Routing Protocol), using the trust evaluation mechanism between neighbour nodes which can effectively prevent attacks from inside the network, to greatly enhance the Ad Hoc Network security. Simulation results show that in low-Rate link environment, the WLRP protocol performs better than AODV.
