Mobility management in Internet of Things applications

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. IoT 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.
