以信息为中心的物联网互联机制研究

Information-centric networking is a new type of network architecture, which is suitable for the Internet of things with mobility as the main feature. At present, the Internet of things is complexity and diversity, and each network uses its own private protocol for communication, which making difficult to interconnection between different networks. To solve this problem, this paper designed the communication gateway which interconnects each Internet of things, for the realization of protocol conversion and data forwarding between different networks. This paper introduced the concept of Information-centric network, then designed the spatio-temporal based naming mechanism to describe the message carriers. On this basis, this paper implemented the protocol translation strategy based on region coverage to solve the transparent transmission of the message carrier in the network. Finally, through the experimental analysis, the gateway module designed in this paper could work well in the experimental environment, and the communication efficiency and the average network bandwidth occupancy were superior to the traditional IP network gateway in the Internet of things.
