The reputation models based on distributed hash table are not suitable for unstructured P2P networks, whereas the existing reputation model for unstructured P2P networks requires a central server for assigning a set of trust management peers for any peer. We present a new reputation model for unstructured P2P networks in this paper. Differing from existing reputation models, in our model, each peer...
As there are many malicious nodes spreading false information in P2P networks, it is of great importance to build a sound mechanism of trust in the P2P environments. To avoid the shortage of the existing trust model, this paper provides a Trust Path-Searching Algorithm based on PSO. In this algorithm, after initializing the particle swarm, each particle can update its speed and location according...
