The Intrusion Detection Method based on Game Theory in Wireless Sensor Network

In wireless sensor network(WSN), intrusion detection systems(IDSs) can be placed on all of nodes to make a network safer. But the always-on strategy is not an efficient choice because of wasting the source of system. The paper describes an intrusion detection way using a non cooperative Game theoretic framework, which can help each cluster head node decide the probability of starting up IDS service. The method not only ensures the security of network, but also reduces the cost caused by monitoring and prolongs the lifecycle of each node. Lastly, the process of corresponding experiments and result analysis has been given in the end of the paper, and the validity of the method has been verified.
