基于演化博弈的多接入网络选择算法
Multi-access network selection algorithm based on evolutionary game

文中针对异构无线网络场景，提出了一种基于演化博弈的多接入网络选择算法。该算法考虑将场景内的所有无线网络作为一个集合，其每一个非空子集作为用户选网方案，从吞吐量和功耗角度分析网络性能，利用演化博弈理论对网络进行动态选择，并运用雅克比矩阵局部稳定性分析法对系统均衡解进行讨论。仿真结果表明，基于演化博弈的多接入网络选择算法相对于单接入算法能够使用户获得更大的吞吐量，并且对应的功耗也相对较小，从而能够更有效地利用网络资源。
A multi access network selection algorithm based on evolutionary game is proposed for heterogeneous wireless networks.The algorithm considers any non empty subset of heterogeneous wireless networks as a selection scheme and the network performance is analyzed from the perspective of throughput and the power consumption.The dynamic selection of the network is regarded as an evolutionary game and the Jacobi matrix local stability analysis method is used to discuss the system equilibrium.Simulation results show that compared with the single access algorithm,the multi access network selection algorithm based on evolutionary game can provide greater throughput for users and the corresponding power consumption is relatively small.Thus,the algorithm can make more efficient use network resources
