A Trust-Based User Assignment Scheme in Ad Hoc Social Networks

Although cooperation among individuals plays a key factor in the commercial development of wireless networks, trust is an important factor due to the uncertainty and uncontrollability caused by the self-organizing character of different entities. In this paper, we present a trust-based user assignment scheme by considering node sociality, the reason behind is that effective user assignment should not only build a reliable system basing on the behavior of network individuals, but also encourage selfish nodes to forward packets for one another. At first, a model for trustworthiness management is built up by considering social relationship. Then, user assignment for each transmission is decided by a double auction-based mechanism. Simulation result demonstrates that our scheme is able to obtain better network performance than the existing method in link connectivity and social welfare.
