A bayesian statistical model for a multipath trust-based reactive ad hoc routing protocol

The recent proliferation of wireless devices extends the scope of mobile ad hoc networks (MANETs) applications beyond the military domain to include civil and commercial application scenarios. Since MANETs are composed of mobile terminals with limited resources, MANET security remains an unsolved and motivating challenge. Due to advantageous like in-frastructureless and spontaneous deployments, MANETs offer an opportunity to set up temporary, dynamic and local networks for no cost. However, some of their characteristics like unreliability of wireless links, dynamic topology, and absence of underlying infrastructure raise some serious problems which become critical when security is also considered. In this paper, we develop a Bayesian statistical model to evaluate the performance of the multipath trust-based reactive ad-hoc routing protocol (MTRP) that combines multipath routing scheme and trust management. In order to analyze security in dynamic networks; two types of events impacting routing performance are considered: mobility and uncooperative behavior.
