无线自组织网络跨层攻击检测博弈模型

无线自组织网络中的跨层攻击具有比单层攻击更强的隐蔽性、更好的攻击效果或更低的攻击成本.为了检测无线自组织网络中的跨层攻击,提出了一种基于博弈论的攻击检测模型.由于攻击不可避免地会对各协议层的参数造成影响,因此模型从协议层攻防博弈的角度,建立起相应的策略矩阵和支付矩阵,并通过均衡分析得到该模型的混合策略纳什均衡解.仿真结...

Game model for detecting cross-layer attacks in wireless ad hoc networks

Compared with single-layer attacks, cross-layer attacks in wireless ad hoc networks can better conceal attack behavior, achieve better attack effects, or reduce the cost of attack. In order to detect cross-layer attacks in wireless ad hoc networks, a detection model based on game theory was proposed. As the attack will inevitably affect the parameters of each protocol layer, the corresponding strategy matrix and payoff matrix was built from the aspect of attack-defense game of protocol layer, and the mixed strategy Nash equilibrium solution was obtained by equilibrium analysis. Simulation experiments results show that the detection system adopting mixed strategy can achieve a better detection performance and save the energy consumption significantly, compared with the traditional detection system.
