MODE SELECTION AND RESOURCE ALLOCATION IN D2D COMMUNICATION UNDERLAY CELLULAR NETWORKS

Abstract

Due to the higher demand for the data rates and massive growing of data and broad band services, Device to device (D2D) communication is considered as an essential part in 5G networks. D2D communication enables the networks to have high data rates, low power consumption and low latency. D2D communication is allowing direct communication between the transmitter and receiver without relaying the data through BS. Four modes of operation are available in D2D communication (i.e Reuse, Dedicated, Cellular and Silent mode). In this work we present a mode selection algorithm based on the relative distances between the node to achieve minimum signal to noise ratio for both Cellular and D2D users.
