Abstract
Aiming at the problem that excessive energy consumption of nodes in each layer protocol design of wireless sensor network will affect the transmission speed of data packets, this paper proposes a medium access control protocol based on continuous listening and hierarchical scheduling, and the upper network is obtained through the interlayer interface Topological structure and routing information to assist in obtaining the channel contention scheme of this layer, and to obtain and maintain a unified hierarchical time schedule based on the clock synchronization mechanism. The data sent and received in the regular active phase can be transmitted to the upper level step by step without stagnation, and when the network traffic exceeds the threshold, the continuous listening mechanism is turned on to offload the sending and receiving of data packets and reduce the probability of receiving conflicts. Simulation analysis shows that this method can dynamically adjust the local time schedule to achieve the goal of reducing energy consumption as much as possible while ensuring real-time transmission.
