Abstract

Utilizing a unmanned aerial vehicle (UAV) to build aerial mobile small cell can provide more flexible and efficient services for ground terminal users. Constrained by the coverage and limited energy of the UAV, it is necessary to study how to build an optimal energy efficient based deployment of UAV. Therefore, objective function is constructed that maximizing the global energy efficiency, subject to altitude and minimum individual date rate constraints. When maximizing the energy efficient, both energy required for communication and energy consume by aerial vehicle, including the energy consumed by the rotor of UAV during climbing and hovering. Sequential convex programming (SCP) and monotonic fractional programming (MFP) are used to solve the objective function. Numerical results show that solution obtained from SCP is the same as the optimal solution form MFP. In addition, there is a gain in energy efficient when the UAV is hovering at an optimal altitude determined by considering the non-zero roto energy consumption of UAV.

Key words： aerial communication system; energy efficient; sequential convex programming; monotonic fractional programming; aerial altitude
