Optimization Deployed Strategy of Wireless Power Beacon based on 5G Millimeter Wave Cooperative Communication Small Cell

To realize the green communication with high spectrum efficiency and low energy consumption in 5G wireless network, a small cell network model of millimeter was cooperative communication of user equipment devices with high-low frequency hybrid networking was constructed for 5G edge network. On the basis of this model, in order to improve the spectrum efficiency and energy harvesting coverage of edge system, an optimized deployment strategy of small cell wireless power beacon based on 5G mm wave cooperative communication was proposed. By minimizing the number of power beacons(PBs) in fixed charging, the normal operation of the system was guaranteed on the basis of minimizing the system energy consumption. As the optimization problem is a NP hard problem, a greedy algorithm with constant factors was designed to approximate the optimization problem. Theoretical analysis proves the feasibility of the algorithm. Simulation results show that this strategy can effectively optimize the PBs deployment, and the energy consumption is the lowest under the same coverage and regional spectral efficiency gain.
