Intrusion detection system for wireless sensor network

Bapna, Deependra (2014) Intrusion detection system for wireless sensor network. MTech thesis.



A Wireless Sensor Network (WSN) is a group of sensor nodes, they monitor a certain environmental information (sound, temperature, motion, pressure, light, etc.), and transmit the information to the base station. Its important to protect the data while information transmitted into the wireless environment. Data can be protected by using cryptographic scheme. a number of attacks can be possible on WSN because of its broadcasting nature, resource restrictions, and remote area of deployment. cryptograpic security can secure network from outside attacks, but fails to protect from inside attack. so we need a second line of defence like Intrusion Detection System.This goal is achieved. PIR motion sensor transmits a signal to base station and the base station trigger an alert message whenever an intruder found into the room. Temperature sensor sends a signal whenever the temperature of room is cross a certain threshold. And light sensor sends a signal whenever intensity of light is cross certain threshold. The attacker node is used to attack on nodes. If IDS found the malicious activity which is done by attacker node, it generates an alert message with the victim nodes information. So we can change the nodes information. As base station is connected to the computer so WSN nodes can be controlled by computer.
