Heterogeneous wireless networks optimal access policy using game competition selecting

为了提高异构无线网络的信息传输速率和网络利用率,减少网络的系统开销,提出一种博弈竞争选择的异构无线网络最优接入策略算法,该算法在考虑了实际带宽的情况下引入了代价因子,并得到最大化的网络信息传输速率。在接入网络的选择上,通过采用基于博弈模型和最优接入策略的博弈模型,通过多项服务质量指标来计算综合竞争值,从而通过竞争值大小来选择最优的接入网络。实验仿真及数据结果表明,相比另外两种异构接入网络的选择算法,该算法具有带宽资源利用率和网络信息传输速率更高的优势。

In order to improve the information transmission rate and network utilization in heterogeneous wireless networks,reducing network overhead,this paper proposed a heterogeneous wireless networks optimal access policy using game competition selecting algorithm,which considering the actual bandwidth under the introduction of a price factor,and maximized network information transfer rate. In selecting the access network,it used the game models and optimal access strategy game model based on the quality of services through a number of indicators to calculate the overall competitive value,thereby to select the optimal value through competitive access network size. Simulation and experimental data results show that compared to the other two heterogeneous access networks,the proposed algorithm has higher bandwidth utilization and network information transfer rate advantage.
