A Bayesian Game Approach for Security Defense Strategy in WSN
Liang Yu, Donghua Qin · 2012
Wireless sensor networks (WSN) are a new selforganizing network as a kind of military applications by RF wireless communications, so its security is very important.Intrusion detection system always be deployed at each node in previous research in defense mechanism in WSN, and it will produce great energy consumption.According to the characteristics of WSN, this paper puts forward a defense model based on the Bayesian game theory in WSN and analyses the game between the attacker and defenders.This model can improve detection rate and show higher energy efficiency.We study the achievable Nash equilibrium for the attacker and defender game in both static and dynamic scenarios.
