[Abstract]:Driven by technology innovation and application demand, wireless mobile communication technology and sensing technology are developing rapidly. The ubiquitous Internet of things communication era is coming. The proposal of the Internet of things not only expands the scope of user terminal equipment, but also expands the deployment scope of terminal equipment. They will be heterogeneous and integrated through various information and communication networks, such as mobile communication network, fixed communication network, Internet, etc. In order to achieve the interaction between people and things, things and things. As an important supporting technology of Internet of things (IoT) communication, mobility management technology has attracted wide attention. Based on the research of Internet of things network communication, this paper summarizes the research and development of mobility management technology and the development of the Internet of things, mainly studies the architecture of the Internet of things, the multi-access technology of the Internet of things. The heterogeneous integration of the Internet of things and the mobility management of the Internet of things based on MPLS and mobile IP are discussed. The main work and research contents are as follows: firstly, the background of mobility management in the Internet of things is introduced in detail according to the mobility management protocol reference model. The current network layer mobility management technology is summarized and summarized. In the research of the Internet of things, the paper defines the Internet of things, discusses the relationship between the Internet of things and the Internet of things, the ubiquitous network and the sensor network, and puts forward a full IP Internet of things. From the point of view of function, the structure of the Internet of things is studied. The analysis shows that the network layer of the Internet of things is a very important layer, no matter whether it is based on the five-layer architecture of the USN Internet of things or the three-tier architecture of the M2M Internet of things. It is the key to information transmission. The Internet of things (IoT) network includes access network and carrier network, which is the basis of object communication in the Internet of things. With the development of modern communication technology, Internet of things (IoT) access technology is also diversified, which makes heterogeneous integration become a major trend of network development. In this paper, the multi-access technology of the Internet of things is comprehensively analyzed, four schemes of heterogeneous integration are discussed, and a simultaneous transmission and seamless mobile scheme in multi-access environment under heterogeneous convergence is proposed. In the aspect of combining mobile IP and MPLS in mobility management, the working mechanism of MIPv6 and HMIPv6 and the working principle of MPLS are analyzed. The improved scheme of HMIPv6 based on MPLS is put forward, and the simulation results are compared between MPLS core network and IP core network. The handoff performance of mobile nodes is discussed, and the next research suggestions on the combination of mobile IP and MPLS are given.
