Security is one of key factors which influence the development of mobile P2P systems. However, traditional security techniques cannot be applied directly to a mobile P2P network due to some of its characteristics such as heterogeneous nature of the peers, limited-range as well as unreliability of wireless links. In the paper, the authors propose a distributed trust evaluation model, which helps the systems to operate normally with high probability. The model uses a polling protocol and seven metrics to real-time evaluate the reputation of mobile peers.
