Maximization Mechanism for Spectrum and Energy Efficiencies in Wireless Networks using Device to Device Communications

Abstract

A linear optimization method along with power control effectively enhances the spectrum and energy efficiencies in D2D networks. In this paper, we propose a linear program for assigning bandwidth to the links based on systems demands, heterogeneity, traffic insertion patterns and network topology. Also, we propose a power control mechanism derived from M-matrix theory to complement the achieved spectrum and energy efficiencies. By the obtained simulation results, it is shown that the proposed mechanisms enhance the spectrum and energy efficiencies by 25% compared to existing methods.
