In this paper, the authors introduce a trust model and a reputation system for wireless sensor nodes in fading multi paths channel. The proposed model establishes the continuous version of the beta reputation system applied to binary events. In doing so, they introduce a theoretically sound Bayesian probabilistic approach for mixing second hand information from neighboring nodes with directly observed information. A trust model in a wireless sensor network addresses the security issue and how to deal with possibly malicious and unreliable nodes.
