Research on Wireless Ad Hoc Network and Equipment Management of Internet of Things Intelligent Node*

摘要

The intelligent node of Internet of things (IoT) is the core device of IoT system in construction equipment. The 433MHz wireless communication technology selected for the intelligent node of IoT has defects in wireless ad hoc network and device management. In this paper, a self-organizing protocol stack is established to solve the problem that the 433MHz wireless communication technology cannot be self-organized. Firstly, the intelligent terminal management is realized by designing the device registration management flow. Secondly, the anti-collision avoidance algorithm is designed in the intelligent terminal to solve the communication conflict problem. Finally, a dynamic routing planning algorithm is designed to solve the signal blocking problem. Finally, the experimental environment was established to verify the correctness and practicability of the method used, and the method was applied to the actual project and has achieved good results.
