Active Trust: Secure and Trustable Routing in Wireless Sensor Network

The proposed ActiveTrust secure and trustable routing system in Wireless Sensor Networks (WSN) improves the security and reliability of data transmission in the network. In this approach, trust values are calculated for each sensor node based on its behavior during communication. Nodes that behave normally and forward packets correctly are given higher trust values, while nodes that drop packets or act abnormally are identified as malicious nodes. By detecting and isolating malicious nodes, the system prevents them from participating in the routing process. The ActiveTrust mechanism selectsrouting paths only through trusted nodes, which helps in ensuring secure and efficient communication between the source node and the base station. This method also considers energy efficiency while selecting routing paths, which helps in extending the network lifetime.
