Efficient device-to-device discovery and access procedure for 5G cellular network

摘要

A large number of new data-consuming applications are emerging, and many of them involve mobile users. In the next generation of wireless communication systems, device-to-device (D2D) communication is introduced as a new paradigm to offload the increasing traffic to the user equipment. Before the traffic transmission, D2D discovery and access procedure is the first important step which needs to be completed. In this paper, our goal is to design a device discovery and access scheme for the fifth generation cellular networks. We first present two types of device discovery and access procedures. Then we provide performance analysis based on the Markov process model. In addition, we present numerical simulation on the Vienna Matlab platform. The simulation results demonstrate the viability of the proposed scheme. Copyright (c) 2015 John Wiley & Sons, Ltd.
