Abstract: The traditional network numerical scheduling method in numerical scheduling and scheduling was low accuracy and low efficiency. On the basis of the routers involved in controlling the network layer, the method based on the use of active queue management (AQM) mechanisms of congestion attack network numerical scheduling was put forward. Application layer on the level of MAC layer channel access control mechanism was used to control the sensor network for solving the congestion. By calculating the number of cache queue packets, the congestion feedback was obtained, the pressure of the local node channel was reduced, the local connection rate was strengthened, and the congestion phenomenon was solved. Simulation results showed that the improved approach had high accuracy and good efficiency. It controlled the network congestion level and improved the service quality of network communication.
