Performance Evaluation of Black Hole Attack in Wireless Sensor Network.

Wireless sensor network are prone to various security threats. Increasing use of sensor networks necessitates that all security issues should be checked a priory. This paper focuses on creation of test scenario to evaluate the performance of sensor system under clone attack. Since clone attack is an insider attack, it may cause severe damage. Cooperative black hole attack is considered as a consequence of clone attack. Simulation scenario is created using MATLAB-2010a and network throughput is considered for performance evaluation.
