Efficacité énergétique des communications Device-to-Device dans les réseaux hétérogènes

Abstract : The objective of this thesis is the study of the energy efficiency of D2D communications in heterogeneous networks. We first propose to analyze the energy consumption of a three device, then introduce a new topology taking into account the data entropy, in order to increase the overall energy efficiency. Subsequently, we study the energy consumption and the influence of interference in a cell for the use case of a natural disaster. We then introduce a new resource allocation protocol based on Fuzzy C-Means clustering. We then use tools and metrics from stochastic geometry to analyze and compare energy and spectral efficiency among multiple types of networks comprising D2D communications. The first study is done on a network in which the cellular and WiFi resources are shared. In a second step, we introduce the notions of directional antennas with millimeter waves. To do this, we evaluate the influence of the mmWave channel and introduce the concepts of blocking, and sectored models of antennas, for mathematical purposes. The use of millimeter waves, and more particularly ULA directional antennas, proves to be a totally appropriate choice in the primary objective of this thesis, which is to increase both the spectral efficiency (therefore the bit rate) and the energy efficiency within a heterogeneous network including D2D communications.
