One routing decision-making mechanism based on cellular address (RDCA) was proposed with the establishment of a three- dimensional communication model. The RDCA established network node data forwarding guidelines based on cellular automata and node average received signal strength. The RDCA completed the route optimization and control by IPv6 addressing. The routing deci- sion- making mechanism was resolved by the cellular address. The simulation results showed that the packet delivery fraction of RDCA was between 82% and 95%, routing consumption ratio was between 20% and 35%, and average end-to-end delay was 20 ms. It can not only ensure IoTs communication per-
