A distributed intrusion detection scheme for wireless sensor networks

The task of Intrusion Detection Systems (IDS) in Wireless Sensors Networks (WSNs) is to monitor sensor network systems; detecting possible intrusions in the WSNs environment, alerting users after intrusions had been detected and reconfiguring the network if possible. In this study a Distributed IDS for WSNs was developed. Distributed IDS is implemented using TMote sky wireless sensor for testing and simulation over specified parameters. For efficient monitoring of the WSNs, the proposed system employs Mobile Agents (MAs) that can communicate with other sensors and move from one Base Station (BS) to another in order to enhance intrusion detection and prevention. Comparative analysis of the result is studied based on three major parameters: energy consumption, response time and detection accuracy. The result of the study shows better performance.
