A Study on Device Discovery for D2D Communication

Abstract

The next generation network, the future of wireless communication 5G, offers a wide range of techniques to improve the existing network characteristics. Among them, a dominant technology to improve the spectrum efficiency and throughput of a network is the Device to Device (D2D) communication. This enables the mobile devices in close proximity to communicate directly by reusing the channel allocated to the corresponding cell. It also improves the data rates, reduces latency and increases system capacity. Identifying the potential candidate for D2D communication is the first and most important step in setting up the D2D communication. In this paper a study on the latest mechanisms to implement device discovery for D2D communication in cellular network is done. Different aspects in three different perspective are presented here.
