Enhanced Beta Trust Model in wireless sensor networks

A distributed and collaborative nature of wireless sensor network cause many challenges to provide security in network. Most of the outsider's attacks are prevented by encryption and authentication technology, but to control insider attacks are difficult. A malicious sensor node causes lot of packet losses, energy wastage and increase in time to reach final destination. In this paper, Enhanced Beta Trust Model (EBTM) is planned to discover malicious attack in wireless sensor network. Recovery procedure is integrated to improve the throughput of network.
