Many existing routing protocols in Mobile Ad hoc Networks (MANETs) focus on finding paths in dynamic networks without considering security. In this paper, we propose a trust model which evaluates neighbours’ direct trust by factors of encounter time, mobility, and successful cooperation frequency.The revised D-S evidence theory is used to combine multiple(More)
Trust management scheme has been regarded as a powerful tool to defend against the wide set of security attacks and identify malicious nodes. In this paper, we propose a trust management scheme based on revised Dempster-Shafer (D-S) evidence theory. D-S theory is preponderant in tackling both random and subjective uncertainty in the trust mechanism. A trust(More)
Trust management is suitable for handling the internal security problems in wireless sensor networks. However, trust management schemes usually neglect the selfishness of normal nodes and regard malicious nodes as never cooperate. Thus, to ensure trustworthiness and encourage nodes to cooperate, incentive mechanisms are in pressing demand for trust(More)
