| 摘 要： | 针对如何在多个异构无线网络中选取最优接入网络问题,提出一种基于模糊层次分析法(FAHP)的异构网络选择算法.首先,为了保证各网络的负载平衡,在进入选择算法之前,对各备选网络进行负载分析；接着,通过对影响网络选择的主要因素的分析,建立网络选择决策模型,同时从用户角度和整体网络管理角度分别计算出各网络属性的权重；最后,综合计算选择最优网络.仿真结果验证了本算法的正确性和有效性.

| Abstract: | This paper studies the problems of how to select the most optimal access network from several heterogeneous wireless networks,and presents an algorithm of heterogeneous wireless network selection based on FAHP.Analysis of the load condition of each optional network is conducted to ensure the network load balancing.Then,a decision model is developed by the analysis of the factors that affect the network selection,the weights of the network properties are respectively calculated from the point of view of user’s perspective and overall network management.Finally,the calculated results are integrated for the choice of the optimal network.Simulation results show the correctness and effectiveness of the algorithm. |
