摘要
无线网络中存在资源瓶颈,而网络中的节点又是理性自私的,这就导致资源分配不均。把无线网络中的资源利用和博弈理论相结合,便产生了基于演化博弈的网络资源利用模型。文中把无线网络中的功率分配,通过演化博弈理论转化为信干噪比收益,最后得到使用功率的迭代公式,与传统的功率分配方法对比后,提出了改进策略,从而为无线网络中的资源利用提供了博弈策略,提高了无线网络的资源利用率,优化了网络环境。
The resource bottleneck in wireless network and the rational selfishness of network node would lead to unfair allocation of the resources. By combining the resource utilization in wireless network with game theory, a network resource utilization model based on evolutionary game is obtained. With evolutionary game theory, the power allocation in wireless network is transformed into SINR gains, and finally the iterative formula of power utilization is acquired. Compared with traditional power distribution methods, an improved method is proposed, and it could provide game strategy for the resources utilization in wireless network. Thus the resources utilization in wireless network is raised and optimizes the network environment optimized.
