Wireless sensor networking is an evolving technology, which supports for many application for common and also military applications. Node compromise is the very important and exclusive security problem in sensor networking. This compromise node which leads to decreased the performance of the whole network. Mainly there are three stages are involving in node compromise attack. Past few years’ node compromise work is tackled second or in third stage. In which addressing the node compromise problem is about first stage and analyzed the performance detection method done by various routing protocols. After that sensor nodes are deployed physically and couple of node is built in ad-hoc patter. Both the node are will monitor periodically send/receive by beacon signal. Couple node will check the received beacon signal and its information. If the information is same it believe that the partner node is not compromised and if it is not same partner is compromised. Likewise building couple of nodes among the neighbor node in local area, physical node can be easily compromised and attack can be detected at higher rate.
