A Reliable Internet of Things Networking Layout Method

Abstract

The invention discloses a reliable Internet of things networking layout method. A base station reader regularly scans mobile label terminals within the directional coverage of the base station reader in a single-node frequency modulation and hopping way, acquires mobile label user identifiers (ID), performs analysis to judge whether information is required to be transmitted to an upper computer or not, and dynamically updates a user register list in real time. In such a novel networking way, a high space coverage rate is realized on the basis of occupying an extremely small number of frequency resources, and the method is high in communication signal quality, low in bit error rate and simple and reliable in communication protocol; and the characteristic that space division multiple access and code division multiple access are easy to implement is effectively integrated on the basis of reserving the characteristics of high isolation among channels in the multi-carrier modulation of a frequency division multiple access method and high directional radiation of a directional antenna, and the whole system has a simple structure, is high in robustness, easy to flexibly design and network according to different application environments and low in cost, and can communicate with a mobile network and the Internet through simple port configuration.

Description
