Energy Efficiency for Device-to-Device Communication based on Lagrange Optimization Technique

Radwa Ahmed Osman


Abstract: Device-to-device (D2D) communication is considered one of the most promising technique for 5G communication. D2D communication allows the cellular user equipment (CUE) to communicate with each other without the need of the existence of base station (BS). In D2D communication, all the devices are sharing the same spectrum of cellular network, this leads to increasing the interference among receiving devices and affecting the system performance. Increasing the system energy efficiency (EE) of D2D communication while maintaining the required performance of cellular network is one of the main issues that should be addressed. This paper aims to optimize the D2D energy efficiency with minimum required cellular network spectral efficiency during downlink data communication. To achieve the goal of the proposed model Lagrange optimization technique is used as optimization method. Based on the optimization technique the m optimum required distance between the transmitting D2D and the receiving CUE to maximize the D2D EE is determined. Simulation results show that the proposed model can reach the optimum energy efficiency of D2D communication and can outperform other existing techniques while keeping the required CUE system requirements.
