With the development of wireless sensor networks,the issue of network security has attracted more and more attention and has become an important research direction. In the existing research on wireless sensor network security,there are generally two related problems:the temporary defense problem and the optimal solution problem. These two issues involve attack methods and defense methods of wireless sensor networks. At present,a large number of literatures have carried out research on anti-defense algorithms,and few scholars have studied attack algorithms. In the field of network security,only a better understanding of attacks can master attack defense techniques. In response to the above analysis,this paper proposes an attack strategy generation model based on Markov Decision Processes(MDP),uses this model to generate an attack strategy against a certain anti-algorithm,and then uses cooperative spectrum sensing attack methods and EWSZOT to defend. The method is taken as an example to analyze in detail the destructive effect of the attack strategy generated by MDP on the EWSZOT defense method. Finally,simulation experiments verify that the attack strategy based on the MDP model can destroy the defense effect of the EWSZOT method to the greatest extent compared with other attack strategies,and the attack success rate of the EWSZOT defense method is higher than 70%.
