针对移动传感网中频谱利用率低以及频谱资源匮乏问题,在假定移动传感网环境中具有多主用户和多次用户的前提下,首先将传感器节点视作具有感知能力的个体Agent;然后根据主、次用户的不同频谱使用权限建立Agent群体对抗的博弈模型,提出一种Agent群体跟踪对抗的频谱分配算法.从而提出一种基于Agent群体对抗的动态频谱分配策略(GCAS).最后从系统分配的效益和公平性两个方面与现有的合作式算法(CSGC)和非合作式算法(GA-SA)做了对比实验,仿真结果表明该方法在兼顾系统的效率的同时能有效地提高频谱利用率和频谱资源分配公平性.
Considering the low utilization of spectrum and the lack of spectrum resources in mobile sensor networks, we first consider the sensor nodes as individual agents with perceived capacity on the assumption that there are multiple owners and multiple users in the mobile sensor network environment. Then According to different spectrum usage rights of primary and secondary users, a game model of agent group antagonism is established and a spectrum allocation algorithm of agent group tracking countermeasures is proposed, so a dynamic spectrum allocation strategy (GCAS) based on agent group antagonism is proposed.Finally, The effectiveness and fairness of distribution are compared with the existing cooperative algorithms (CSGC) and non-cooperative algorithms (GA-SA). The simulation results show that this method can effectively improve the system efficiency Spectrum utilization and allocation of spectrum resources fairness.
