Reputation-based trust management in wireless sensor networks

Wireless sensor networks are promising future of many sensitive applications such as healthcare, defence, habitat monitoring and early bushfire detection. These networks are prone to security attacks due to their wireless and deployment nature. It is very likely that after deployment of the network, sensor nodes are left unattended which causes serious security concerns. Insecure wireless communication aggravates the inherent vulnerabilities of wireless sensor networks. This paper is to study the reputation and trust management and setting a scene to integrate the trust in a security framework to ensure the reliability, integrity and trustworthiness of data sensed by the sensor nodes.
