Energy efficiency optimization of relay-assisted D2 D two-way communications with SWIPT
文献摘要：
Aiming at the energy consumption of long-distance device-to-device (D2D) devices for two-way communications in a cellular network, this paper proposes a strategy that combines two-way relay technology ( TWRT) and simultaneous wireless information and power transfer ( SWIPT) technology to achieve high energy efficiency ( EE ) communication. The scheme first establishes a fractional programming problem to maximize EE of D2D, and transforms it into a non-fractional optimization problem that can be solved easily. Then the problem is divided into three sub-problems:power con-trol, power splitting ratios optimization, and relay selection. In order to maximize EE of the D2D pair , the Dinkelbach iterative algorithm is used to optimize the transmitted power of two D2 D devices simultaneously;the one-dimensional search algorithm is proposed to optimize power splitting ratios;an improved optimal relay selection scheme based on EE is proposed to select relay. Finally, experi-ments are carried out on the Matlab simulation platform. The simulation results show that the pro-posed algorithm has faster convergence. Compared with the one-way relay transmission and fixed re-lay algorithms, the proposed scheme has higher EE.
