FHGM: A Frequency Hopping Game Model with Communication Security Awareness for WSN

Wireless sensor networks (WSNs) are in an open wireless environment which is complex and volatile, and often subject to inadvertent or intentional interference, sensor networks can use frequency hopping technology to get away from the interference. Therefore how accurate and timely frequency hopping is particularly important issue. To solve that, this paper built a Bayesian frequency hopping game model based on Nash equilibrium game theory. The formal definition and quantified description of the impact factors in the game model are described, and Bayesian Nash equilibrium is proved. Through the simulation and analysis shows that this model with communication security awareness can improve the accuracy of the frequency hopping, make the time of frequency hopping become more rational, prolong the network lifetime and maintain the overall network connectivity.
