Novel research of intrusion detection based on repeated game in wireless sensor network

When things in the presence of attack node,the current study method for unconstrained function.This paper proposes a novel intrusion detection model with punishment based on repeated game.If a malicious node attacks at this time,the act will effect it's utility at next time.Base on this,this paper gave a punish method,in this method,the probability of a node chooses attack would reduce,and analysis the future payoff expectations,the detection rate of intrusion detection.Simulation results show that,this model can effectively curb the node attack when a malicious node attacks the network.
