A Review on Intrusion Detection Schemes in Wireless Sensor Network?

Modern wireless sensor networks require specific and high degree of security due to their limitation and versatility tasks. Their limited computational ability and battery resources restrictions make them vulnerable to many kinds of attacks. Little real-world data is available about the insider threat. This ―insider threat‖ has received considerable attention, and is cited as one of the most serious security problems. The goal of this paper is to provide a detailed review about different techniques available for detecting an intrusion along with their characteristics and advantages.
