An Independent Trust Routing Framework Based on Trust Topology Control

The decentralized distributed system characteristics of ad hoc networks bring up some security problems. To ensure the safe, efficient and flexible data transmission in ad hoc networks, this paper presents a trust routing framework based on topology control theory. This framework establishes a trust topology layer independent of routing layer, and the routing procedure executes over the trust topology generated by a distributed topology control algorithm. And in our algorithm, the trust topology is constructed through trust triangles which are generated by multi-objective decision. At last, a dynamic trust management scheme to update the trust topology is presented. Experiments show that the method proposed in this paper performs well and works even more efficiently in mobile scenarios.
