传统网络切换仅依赖于数据链路层接收的信号强度.最近的研究尝试综合网络各个层次的信息做出更为智能的决策,然而这些参数不容易测量和量化.为了找到最优切换策略,将这些与切换相关的信息分为基本信息、网络信息和用户信息,并提出了基于模糊逻辑的无线网络切换算法,以对不同网络层次的参数进行收集、处理和保存,同时根据这些参数所属类型,设置不同的权重值来适应不同的应用场景,以达到良好的环境感知和符合用户个人偏好的智能选择.系统仿真结果显示,切换准确率和用户期望契合度进一步提高.
Traditional network handover depends only on the signal strength received at the data link layer.Recent research attempts to make more intelligent decisions by synthesizing information at all levels of the network, however, these parameters are not easy to measure and quantify.In order to find the optimal handover strategy, The information related to the handover is divided into basic information, network information and user information, and a wireless network switching algorithm based on fuzzy logic is proposed to collect, process and save the parameters of different network levels. At the same time, according to the type of these parameters, Set different weights to adapt to different application scenarios, in order to achieve a good environment perception and intelligent choices that meet the user’s personal preferences.The simulation results show that the accuracy of handover and user expectations fit further improved.
