摘要
为提升无线异构网络用户体验及服务质量,提出基于实时多业务的异构网络选择算法。该算法考虑多业务的主客观属性,重新定义和构造了判断矩阵,基于AHP(Analytic Hierarchy Process)算法和熵权法综合计算属性权重,最后利用TOPSIS算法选择出最优的接入网络。仿真实验结果表明,实时多业务网络选择算法能够有效地减少切换次数,在兼顾网络负载的情况下,降低了业务的阻塞率。
A heterogeneous network access selectionalgorithm based on real-time multi-service is proposed to enhance the user experience of wireless heterogeneous networks and quality of service. The algorithm takes the objective and subjective attributes of multiple services into account, redefining and constructing the judgment matrix algorithm based on AHP and Entropy Comprehensive calculate attribute weights. Finally, the optimal network access is selected by utilizing the TOPSIS algorithm. Simulation results show that real-time multi-service network selection algorithm can effectively reduce the switching frequency, it not only ensures the network load but also reduces the blocking rate of services.
