This paper introduces 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, we 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. Although encryption and cryptography keys are used, these deterministic approaches fail to answer the problem of securing the routing and content of information through a network. Reputation systems are developed to combine with deterministic measures to secure the integrity of a network. Previous research focused on binary transactions in a network, such as routing. This paper introduces Trust model for continuous data in multi paths fading channel.
