Different from most of past routing algorithms which only considered shortest path first or evaluated the trust level solely on the forwarding behavior or were dependent on reputation recommendation mechanism,we proposed a novel subjective trusted routing model under consideration to both communication reliability and path length, Inspired by the establishment pattern of trust relationships in human life,we introduce the concept of attribute similarity to inherently bind neighbor selection, trust evaluation, packet forwarding, and other routing processes. Simulations show that the proposed trust routing model behaves better than dynamic source routing protocol on defending against malicious nodes. Also we provided some numerical results about the impacts of different communication ranges, moving speeds and node numbers on performance.
