基于异构无线网络的赋权算法

随着无缝连接技术的发展，以多媒体应用服务为核心的无线电技术必须满足用户网络服务质量的要求. 对于异构无线网络，可能发生不同技术和管理域之间的切换，切换判决不再基于某一参数而是建立在多属性综合考虑的基础上. 该文就是针对多属性中各参数权重值的确定进行研究，通过对层次分析法、变异系数法、熵值法3种权重赋值方法进行分析，在不同业务类型下对异构无线网络指标进行评价.

Weighted Algorithm Based on Heterogeneous Wireless Network

With the development of seamless connection technology, multimedia applications as the core of the radio technology must meet user networks'' requirements for service quality. For heterogeneous wireless networks, switching between different technologies and management domains may occur, and the handoff decisions is no longer based on a parameter but on a multi-attribute synthesis. This paper studies the determination of the weight value of each parameter in multiple attributes. Through the analysis of three kinds of weight assignment methods: analytic hierarchy process, coefficient of variation method and entropy method, the heterogeneous wireless network metrics are evaluated under different business types.
