A Power Peer-Based Reputation Scheme for Mobile P2P Systems

Lack of trust between peers is one of the most serious drawbacks that obstruct the wide adoption of mobile p2p systems. Since current reputation schemes developed mainly for the fixed wired networks are not fit in such a scenario, new trust solutions are eagerly in demand. This paper presents a power peer-based reputation scheme, where peers are classified into two groups, power peers and mobile peers and a power peer has zero or more mobile peers. We design two ways of selecting power peers, greedy method and maximal independent set method. The proposed scheme establishes a trusted mobile environment for mobile p2p systems. It effectively avoids the communication overhead in global trust computation because each power peer maintains the appropriate reputation information of its mobile peers. The simulation results show that our scheme is highly robust and scalable in the dynamic environment of mobile networks.
