The dynamic characteristics of Internet of Things related equipment require that the routing protocol not only possess the characteristics of low energy consumption, but also adapt to the characteristics of dynamic network environment. In this study, a dynamic routing algorithm based on LF-GFG is proposed based on the right hand rule of traditional location routing protocol and the easy realization of virtual coordinate system. The results of the NS-2 experiment show that the algorithm reduces the maintenance cost, improves the processing speed, and maintains a higher fault tolerance than other routing protocols.
