Wireless Sensor Networks (WSN) is tiny independent devices enclosed firmly in surrounding nodes, able to communicate using wireless links. A wireless sensor network holds huge number of nodes they are spread in antagonistic and nodes are unattended. So, they are easily tracked by the adversary with no protection. An opponent can hold and compromise some node to initiate to make duplicate of them. Once a node is capture, adversary can easily insert replica nodes at any location in the wireless sensor network.
