Abstract

In this paper, we investigate the performance analysis of the buffer-aided energy harvesting device-to-device (D2D) communication system. A joint data and energy resource scheduling problem is proposed considering the data packet and energy packet Poisson arrival but interactive departure. Considering the coupling relationship between data and energy, the joint resource scheduling problem is modeled as a data and energy coupled queuing model. We raise the expressions of carrier-to-interference and noise-ratio (CINR) interval division, which contains the dynamic interferences from cellular users and the other D2D users. To compromise between data delay and energy consumption, we propose a novel adaptive power transfer (APT) strategy that allows more energy consumption to improve data delay. Studying user mobility and APT strategies will lead to complex boundary behavior of the system transition state matrix. By random geometry theory and quasi-birth and death method to obtain steady-state transition probability, the expressions of throughput, delay and packet drop rate for both data queue and energy queue are derived. Simulations are demonstrated to verify the accuracy of the theoretical derivation results.

Summary

INTRODUCTION

On June 6, 2019, the Ministry of Industry and Information Technology officially issued 5G commercial licenses to China Telecom, China Mobile, China Unicom and China Radio and Television in Beijing, which marks the official entry of China’s 5G into the first year of commercialization. [4] studied the problem of resource allocation with dynamic data arrival and limited buffers in D2D communication networks and modeled it as a constrained Markov decision process (CMDP). Considering the joint data-energy beamforming technology, [21] proposed a synchronous wireless information and power transmission-based traffic offloading scheme for EH D2D communication cloud wireless access networks. We concentrate on the performance analysis of the data and energy coupling queuing model based on random geometry for buffer-aided EH D2D communications networks. D2D users need to make full use of energy resources to send data resources efficiently under complex channel conditions In this buffer-aided EH D2D underlaying cellular networks, the interference of typical D2D users comes from the other D2D users and cellular users that obey PPPs. Second, the continuously changing channel state process is divided into several intervals to analyze and.
