Multi-agent information fusion based trust routing framework for mobile ad hoc network

With the rapid development of mobile ad hoc network, security and trust are important to the network. Trust routing framework is the main issue in mobile ad hoc network. Trust routing is related to many factors such as hop number, node residual energy and node behavior. To use the multi-source information fully, multi-agent information fusion method is used to design trust routing framework. The definition of trust routing is proposed in the paper. Ad hoc On-Demand Distance Vector (AODV) routing protocol is used to validate trust routing framework, Route Reply (RREP) Message is extended to record node residual energy and behavior information. Ns-2 is used to simulate different network scenarios. Simulation results show that the trust routing framework can improve the efficiency of network and extend the service lifetime.
