摘要
分析通信网络中接入控制的研究现状,了解典型的接入选择算法和通信网络特点,提出一种基于负载均衡和信道分配的接入选择策略。该策略通过对用户移动速度和RSSI(信号强度)进行预处理,获得候选网络集。同时,综合考虑网络环境和用户环境,对不同参数设定相应的权重值,通过多属性决策得到候选网络排序。最终,选择效用值最大的网络进行接入,接入网络时根据不同业务优先级进行带宽分配,若接入网络满足带宽要求则接入业务,否则选择次优网络实施接入。
The research status of access control in communication networks is analyzed,to understand the typical access selection algorithm and the characteristics of communication network,A new access selection strategy based on load equalization and channel allocation is proposed,which is used to preprocess the user’s moving speed and RSSI(signal intensity) to obtain the candidate network set.Considering the network environment and user environment synthetically,the weights of different parameters are set and the candidate networks are sorted by multi-attribute decision.Select the maximum utility value of the network access,according to the different business priorities for bandwidth allocation access to the network. If the access network to meet the bandwidth requirements,it will access the service.Otherwise the sub optimal network will be selected to implement the access.
