一种适用于5G融合网络的接入选择算法

摘要

A new algorithm GAHP(grey analytic hierarchy process)for access network selection in 5 G integrated networks is proposed.Firstly,this algorithm,which is based on analytic hierarchy process,takes the preference of users and param-eters of network performance for the purpose that the QoS parameters are chosen and processed separately.Then,it trans-fers user preference into quantity parameters with the Fuzzy Theory and filters the QoS parameters through the Grey Theory. Finally,candidate networks are ranked and chosen.Simulation indicates that GAHP performs better than traditional net-work selection algorithms,and it can select the best network faster and more accurately,which will improve user satisfac-tion.%提出一种适用于5 G融合网络的接入选择算法：灰色层次分析法（grey analytic hierarchy process，GAHP）。该算法基于层次分析法的思想，结合网络性能和用户体验类指标选出QoS参数，对其进行分类处理；运用模糊理论将用户偏好转化为定量参数，结合灰色关联法对 QoS 参数进行筛选，并对候选网络进行排序选择。仿真表明， GAHP在负载均衡方面优于传统算法，可以更加快速准确地选择最优网络，提高用户满意度。
