Detection Collision Attacks In Wireless Sensor Network Usingrule-Based Packet Flow Rate

摘要

The increa sed deployment of ubiquitous wireless sensor (WSN) networks has exponentially increased the complexity to detect wireless sensor network attacks and protect against them. In this paper, we consider the collision attack that can be easily launched by a compro mised (or hostile) node: a co mpromised node does not follow the medium access control protocol and cause collisions w ith neighbor transmissions by sending a short noise packet. This attack does not consume much energy of the attacker but can cause a lot of disruptions to the network operation. Due to the wireless broadcast nature, it is not trivial to identify the attacker. This paper describes detection algorithms for wireless sensor networks, w hich detects collision attack based on the packet flow rate to base station node in the network. Simulation results show that the algorithms have low false toleration and false detection rates and small time to detect attacks
