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 management schemes. We propose an incentive mechanism...
Network security will face tougher challenges for MANETs due to emerging purposive strategic attacks conducted by smart malicious nodes. All these purposive strategic attacks eventually run out of the throughput which results in network crashes. In this paper, we have proposed a two-level dynamic Bayesian game model to recognize these purposive strategic attacks in MANETs and establish a malicious...
