A Multi-Parameter Trust Framework for Mobile Ad Hoc Networks

This chapter presents a novel trust model called Multi-Parameter Trust Framework for Mobile ad hoc networks (MTFM). A key feature of this proposed framework is its use of multiple rather than a single parameter to decide the resulting trust value, applying Grey theory. Results presented here demonstrate that the new framework can maintain consistent trust values in the presence of various types of mobility. Simulations conducted in an 802.11-based mobile ad hoc network also show that this framework offers good robustness in misbehaviour detection by employing multiple parameters. The detection capability of the new framework is examined for a range of misbehaviours and its performance is compared to existing single-parameter approaches, such as the Beta distribution method.
