Cross –Layer Intrusion Detection System for Wireless Sensor Networks

213-220In Wireless Sensor Network, the sensor nodes monitor any abnormal events occurring around the business environment to report the emergency alert whenever it detects any abnormality in an environment or report the monitored data continuously or periodically to the base station. These emergency alerts can be stolen or modified by the attackers or in some cases, the sensor nodes can be physically compromised by the attackers, which lead to an unsafe environment. To avoid these problems, Intrusion Detection System is implemented at the base station to filter the abnormal data mostly related to the attacks of network layer. But this paper proposes a novel cross layer rule based intrusion detection system to detect the attacks coming from different layers in Wireless Sensor Networks. The method analyzed several detection rules for Physical, MAC, Network and Application layer attacks. The implementation is done using the rules identified from the IDS techniques available for Wireless Sensor Network. The experimental result shows the detection rate of different attacks on different layers. The performance of cross layer IDS are shown in the graph by making the comparison between the detection rates of various IDS techniques
