摘　　要：为提高异构网络的接入性能,提升用户体验,文章提出了一种基于组合权重和多属性决策的异构网络接入算法,该算法可以根据用户业务特性的不同,使用熵权法和模糊层次分析法(FAHP)分别计算网络属性的主观权重和客观权重,然后根据组合权重,使用VIKOR计算网络的最后分值,将网络排序,进行了异构无线网络的接入。最后进行了所提算法与其他3种算法(Entropy-FAHP-SAW、Entropy-FAHP-MEW、Entropy-FAHP-TOPSIS)的对比仿真实验,结果表明,算法在保障业务用户Qos的基础上,降低了网络的切换次数、切换失败,减少了乒乓效应,提高了接入判决的服务质量。In order to improve the access performance of heterogeneous networks and improve user experience,this paper proposes a heterogeneous network access algorithm based on combined weights and multi-attribute decision-making.This algorithm can use the entropy weight method and FAHP to respectively calculate the subjective weights and objective weights of network attributes according to different user service characteristics,and then uses VIKOR to calculate the last score of the network according to combined weights,sort the network,and access heterogeneous wireless networks.Finally,the comparison and simulation experiments of the proposed algorithm and other three algorithms(Entropy-FAHPSAW,Entropy-FAHP-MEW and Entropy-FAHP-TOPSIS) are carried out.Results show that the algorithm reduces the number of network switching times and switching failures,reduces the ping-pong effect and improves the service quality of access judgment on the basis of ensuring Qos for service users.
