| 摘 要： | 为了解决5G异构网络在切换过程中单一处理切换参数的片面性问题，提出了一种适用于5G的新的切换算法，该算法基于多属性分块决策（modular multi-attribute decision making，M-MADM）理论，把切换参数分为2个模块，采用TOPSIS与层析分析相结合的方法选择最优网络QoS（network QoS，NQ）模块，其次利用模糊逻辑得到用户偏好（user preference，UP）模块，再对最终满意度（degree of satisfaction，DS）模块作一次模糊处理，选择最优结果执行切换。仿真结果表明，M-MADM算法与传统算法相比，可减少时延，降低切换失败率，并能快速准确地切换至最优网络，提高用户满意度。

| Abstract: | In order to solve the problem of unilateral processing parameters of switching for 5G heterogeneous networks, a new handoff algorithm based on modular multi-attribute decision making(M-MDAM) is proposed. M-MDAM divides hand-off parameters into two parts, firstly, a method combining TOPSIS and AHP was used to select the best network QoS(NQ) module; Secondly, using fuzzy logic to get user preference(UP) module, then made the degree of satisfaction(DS) module for a fuzzy treatment, choosing the best optimal network to perform handover. Simulation results indicate: M-MDAM algorithm not only reduces switch delay and handoff failure rate, but also selects the best network faster and more accurately,which will improve user satisfaction. |
