Intrusion Detection System Based on Payoff Matrix for Wireless Sensor Networks
Rongsheng Dong, Lianglong Liu, Jianming Liu, Xuliang Xu · 2009
The high node density, large scale node number and limitation of resource in wireless sensor networks introduce significant challenges when preventing active denial of services (DoS) attacks. This paper established an attacking-defending gaming model, where the strategy space and payoff matrix are given to both the intrusion detection system (IDS) and the malicious nodes. The Nash equilibrium of mixed strategy is then achieved. Simulation results show that our gaming model can detect active DoS attacks effectively.
