A distributed trust management model for mobile P2P networks
In this paper we propose a distributed Trust Management Model (DTMM) for constructing much shorter and more robust trust chains in mobile p2p networks. With DTMM, each moving object within the same group tends to have a high probability of keeping stable distances from each other. The main contribution of this model is to predict the future availability of wireless links and lead to fast generating valid trust evidences. A major difference between DTMM and many existing models in trust literature is that DTMM does not rely on any fixed networking infrastructure, and therefore is able to adapt to both high mobility environments. Our work appears to be the first attempt to research the relationship between mobile patterns and trust management of peers in mobile P2P network. The simulation results show that our model is highly robust and scalable in the dynamic environment of mobile networks.
