通信技术的宽带化、大容量需求,使得频率资源和系统容量的矛盾变得越来越突出。为了解决这一矛盾,形成了蜂窝移动通信网络以及无线城域网、无线局域网、无线个域网、无线传感器网络、无线自组织网络等多种网络共存的异构网络环境,异构网络融合技术成为国内外的研究热点,由此产生了网络选择、资源分配和管理、中继和协同等诸多急需研究的课题以及各种各样的具体应用。为此,本专题组织了9篇文章,以期对从事异构网络研究 Broadband communications technology, high-capacity needs, making the conflict between the frequency resources and system capacity has become increasingly prominent. In order to solve this contradiction, a heterogeneous network environment in which a variety of networks such as a cellular mobile communication network and a wireless metropolitan area network, a wireless local area network, a wireless personal area network, a wireless sensor network and a wireless ad hoc network coexist is formed. Heterogeneous network convergence technologies Has become a research hotspot both at home and abroad, resulting in many urgent research topics such as network selection, resource allocation and management, relaying and coordination, and various specific applications. To this end, the thematic organization of 9 articles, in order to engage in heterogeneous network research
