Multi-constraint-based Vehicle Communication Model-aided UAV under Intersection Scenario
For intersection scenario of vehicle-to-everything,communication model based on Un-manned Aerial Vehicle(UAV)acting as roadside unit is proposed in this paper.With delay and backhaul link capacity as constraints,power optimization problem of UAV is constructed,which is about three-dimensional position(horizontal position and height)and power allocation of UAV.Then minimum rate required by the vehicle user to is derived.The problem is solved by sequential quad-ratic programming.Finally,the influence of the violation probability and the packet size transmitted by the vehicle user on the power consumption of UAV is analyzed by simulation.Performance analy-sis shows that load ratio of backhaul link increase with the increase of packet size when required de-lay is very small.The results provide the reference for deploying UAVs-aided vehicle-to-everything.
