Abstract

Due to the dynamic nature of P2P systems, it is difficult to keep a global trust of the system by analyzing all nodes´ state which will increase node load. This is why it is important to develop a trust mechanism that uses as little nodes as possible to judge the global trust. In a SuperPeer-based p2p system using the superpeers (SPs) as management nodes can allow trust mechanism to be developed that consume less system resources and lighten nodes´ load. In this paper we extend a SP choice method to include the transfer of credit between SPs and that from ordinary peers (OPs) to SPs. and The model based on this method is implemented to prove that it can provide a more trust mechanism solution for P2P files sharing system.
