Abstract
In this paper, we study the energy efficient communication of a fuel-powered UAV relay. Since the fuel-power UAV has separate power supply for communication and operation, and the fuel can support hours’ flight, we focus on the energy efficient communication of the UAV. We study two scenarios as a comparison, including the UAV working as a one-way relay and a two-way relay. The non-convex optimization problem is solved using successive convex approximation (SCA) method and difference of convex functions (DC) programming. The upper bounds and lower bounds of the data rates are proposed to transform the problem to an equivalent convex optimization problem. Numerical results show that the proposed upper bounds and lower bounds of the data rates converges to the same value. And the convergence of the objective function is also shown. The differences of the UAV’s placement and power allocation as a one-way relay and a two-way relay are compared in the discussion.
