Abstract: Aiming at the problem of poor control of highspeed Internet communication coverage, we proposed an optimimal control algorithm for highspeed Internet coverage in heterogeneous environments based on energyload balancing control. Firstly, a node deployment and route detection model of highspeed Internet in heterogeneous environment was constructed, and a load balancing control protocol of an adjacent route was used to optimize the design of route protocol. Secondly, the energy load balancing control algorithm was used to improve the coverage of the highspeed Internet. The simulation results show that the control algorithm can realize the route equilibrium control of the highspeed Internet in the heterogeneous environment, the balance of the network channel transmission and the antiinterference ability are good, and the coverage of network communication is high under the condition of minimum nodes, which improves the load imbalance caused by low coverage.
