A Stable Group-Based Trust Management Scheme for Mobile P2P Networks
Mobility, uncertainty and heterogeneity of mobile P2P systems make trust management much more complicated, so current existing trust models or trust management systems are inadequate in the mobile computing environments in which the clients are mobile, volatile and undetermined. In this paper, the authors propose a novel Stable Group-based Trust Management Scheme (SGTMS). Within the same stable group, mobile peers are geographically and operationally close, i.e., sharing common mobility and tend to have a high probability of keeping stable distances from each other. Therefore, sufficient and reliable trust relationships are constructed in the group without relying on any fixed networking infrastructure or centralized entities.
