时隙接入策略下联盟形成博弈抗干扰方法

Coalition Formation Game Based on Anti-jamming Slot-Access Approach

针对无线通信环境中动态变化的恶意干扰信号和内部同频互扰同时存在的问题,提出了一种基于联盟形成博弈的抗干扰时隙接入方法。利用联盟形成博弈思想,将干扰攻击影响下的通信收发对时隙接入问题建模为抗干扰联盟形成博弈问题,通过调整时隙接入,以最大化全网的平均和速率,同时兼顾用户的最低速率为优化目标,分析了所提博弈模型的性质,设计了基于最优响应的抗干扰时隙接入算法,并对算法的收敛性、稳定性、最优性、复杂度和公平性进行了讨论。仿真结果表明,相较于对比方法,所提方法可以有效降低内部同频互扰和外部恶意干扰的影响,从而实现高效抗干扰数据传输,且该方法的公平性较好。

In order to address the problems of dynamic malicious jamming signals and co-channel interference in the wireless communications environment,an anti-jamming slot-access method based on coalition formation game theory is proposed.Firstly,with the concept of coalition formation game,the slot-access issue under the influence of jamming attacks is modeled as an anti-jamming coalition formation game.Secondly,by adjusting slot accesses,the properties of the proposed game model are analyzed with the optimized objective of maximizing the rate of averaged sums while taking into consideration users'minimum rates.Thirdly,an anti-jamming slot-access algorithm based on best response is designed,and the convergence,stability,optimality,complexity and fairness of the algorithm are discussed.The simulation results show that the proposed method with better fairness can effectively reduce the impact of co-channel interference and external malicious jamming so as to achieve efficient anti-jamming data transmission,compared with the benchmark methods.
