Trust Computation in WSN System

Wireless sensor networks (WSNs) are emerging as a valuable technique for extracting information from the surrounding environment by deploying a large number of small-sized sensor nodes in sensitive, unsupervised, and (often) hostile environments. Traditional cryptographic methods are commonly used in WSN security. However, due to unattended and insecure deployment, a sensor node may be physically captured by an adversary who may obtain the underlying secret keys, or a subset thereof, in order to access the important data and/or other nodes in the network. Furthermore, a node might not function correctly due to a lack of resources or issues with the network link. In recent years, WSNs have been used to monitor the shifting behaviors of nodes in a network by using the fundamental concepts of trust and reputation. In light of these circumstances, we provide a Trust Computation in WSN System in this work. a Java-based trust and reputation models simulator designed to make it simple to test and evaluate trust and reputation models over WSNs. It allows the user to change numerous parameters, like the percentage of malicious nodes and the possibility of creating a collusion, among many others.
