A New Incentive Based Algorithm for Avoiding Free Riding in Peer to Peer Network

摘要

A peer-to-peer (P2P) network undergoes various type of cheating attacks. In recent literature, to combat this attack, various trust value-based mechanisms are employed. These mechanisms decrease the trust value of malicious nodes and counter many types of attacks. But this does not solve the problem of non-participation or free riding fully. Here, we propose an incentive based simple yet effective scheme for avoiding free riding taking trust value of nodes into account. The proposed scheme helps reducing non-participation in P2P networks. The results show that the scheme is efficient for a P2P network of few tens of nodes. With slight modifications, this mechanism can be extended for large sized networks.
