摘要
物联网(Internet of Things,IoT)是继计算机、互联网与移动通信网之后世界信息产业的第三次浪潮,其相关研究及应用已引起国内外研究机构及业界的高度关注。典型物联网应用,如智能交通、远程目标监控、智能家居等均存在终端设备独立或群组移动的应用场景。物联网应用中智能终端异构、高混杂;接入网络多元化、动态融合;用户业务丰富多样等特征,对传统的网络控制技术,特别是移动性管理技术提出了新的挑战。对物联网移动性管理体系架构、移动性管理协议以及相关控制机制的研究基础及现状,面临的困难及挑战,以及未来研究方向进行阐述。
The quick development of Internet of Things （IoT） brings tremendous influence on world information industry, following the development and application of computer, internet and mobile communications, loT related research and application have raised considerable attention from academy and industry over the world during the past several years. The scenarios of terminal moving individually or in group are commonly employed in typical IoT applications, such as smart transportation, remote target monitoring and smart home, etc. The characteristics of heterogeneity and deep mixing of smart terminals, the diversity and dynamical integration of access networks, and the variety and flexibility of user traffic services pose big challenges to traditional network control technologies, especially the technology of mobility management. In this paper, an overview of current research work on system architecture, protocol and control mechanisms of mobility management in IoT related applications is given, the difficulties and challenges are pointed out, and future research directions on mobility management in IoT system are discussed.
