CTrust: Trust Aggregation in Cyclic Mobile Ad Hoc Networks

In a Cyclic Mobile Ad Hoc NETwork (CMANET) where nodes move cyclically, the authors formulate trust management problems and propose the cTrust scheme to handle trust establishment and aggregation issues. Unlike trust management in conventional Peer-To-Peer (P2P) systems, trust management in MANETs is based on simple neighbor trust relationships and also location and time dependent. In this paper, they focus on trust management problem in highly mobility environment. They model trust relations as a trust graph in CMANET to enhance accuracy and efficiency of trust establishment among peers. Leveraging a stochastic distributed Bellman-Ford based algorithm for fast and lightweight aggregation of trust scores, the cTrust scheme is a decentralized and self-configurable trust aggregation scheme.
