Executive Summary

Wireless sensor network becomes popular both in civil and military jobs. WSNs are of particular interest to adversaries due to their frequent deployments in open and unprotected environments. Sensor nodes have limited communication capability and low computation resources so each node is weak entity that can be easily compromised by adversary by launching malicious software inside the network As cryptographic mechanism is not enough to protect sensor network from external attacks, intrusion detection system needs to be introduced. Many mission critical wireless sensor networks require an efficient, lightweight and flexible intrusion detection algorithm to identify malicious attackers.
