Intrusion Detection System in Wireless Sensor Network

Security is a significant concern for many sensor network applications. Intrusion detection is one method of defending against attacks A Wireless Sensor Network consist of large group of Sensor nodes that, senses specified parameter(s) related to environment; processes data locally or in a distributed manner and route the processed information to the central Base station. The Base station analyzes received information and initiates suitable response if required. In this paper we are taking the scenario for military setup, where it requires tight security to protect deployment area form an intruders, malicious attackers for entering in the restricted premises and compromising its security. In this paper, we describe the design and implementation of a system capable of effective deployment of sensor, detecting intruders. In addition we also evaluate the energy consumed for detection and routing information towards the Base Station.
