Based on the background of the Internet of Things, this paper proposes a communication node information transmission protocol for wireless network sensors. This method adopts the strategy of alternating listening and sleeping. It can also reflect the overall characteristics of the monitoring range while meeting the real-time requirements. The protocol method proposed in this paper has the characteristics of low energy consumption and no synchronization. The algorithm reserves multi-hop timeslots at one time in the data forwarding direction at the frontier of data transmission. It avoids the delay caused by intermittent transmission of single-packet data on the forwarding path. The simulation results show that the energy efficiency and delay performance are much better than SMAC.
