Abstract

Wireless sensor network is most widely used technology in number of monitoring and tracking tasks. In many such cases security is major issue of concern. Security is required to avoid any kind of interference which occurs due to lack of gateways and switches. The intruder must be detected before it harms the network. In order to protect WSN from various kinds of attacks number of algorithms has been developed. In this paper we purpose a new intrusion detection scheme by using ant colony optimization technique in heterogeneous environment of sensor nodes. With varying the density in précised manner results will exponentially increases to detect intrusion in particular area. Our result shows that detection probability increases by applying ACO in heterogeneous environment.
