Device to device communication: A survey

Journal of Network and Computer Applications, 2019
Abstract With the advanced communication technology, the number of users and applications are increasing exponentially leading towards the scarcity of resources and an increase in power consumptions. The data traffic on the base station also rises with the number of users.

Latency Aware NOMA Based Device-to-Device Communication

2018 European Conference on Networks and Communications (EuCNC), 2018
Device-to-Device (D2D) links in cellular networks are expected to satisfy the increasing the local data traffic demands. This technique aims to admit more users into the network, providing spectral gains over traditional cellular communication. In this paper, we study a latency-aware resource allocation problem in which cellular devices in proximity ...

User Discovery in Device-to-Device Communications

2020 28th Signal Processing and Communications Applications Conference (SIU), 2020
In this article, user discovery simulations are carried out in device-to-device communication in medium of Matlab within the frame of 3GPP standards. In this study, the random backoff method that has been touched upon several times in related literature and binary exponential backoff that has been used in IEEE 802.11 are compared.

Device-to-Device Communications: A Contemporary Survey

Wireless Personal Communications, 2017
Device-to-device (D2D) communication is a new enabling technology for the next generation cellular networks. In D2D communications, two or more user equipments directly communicate with each other with a very restricted involvement of the evolved Node B. The main objective is to realize high data rates, low power consumption, low delays and improve the

Cooperative Device-to-Device Communication Architecture

2014
This chapter presents the architecture of cooperative device-to-device communication in a multi-cell multi-channel wireless network. Two cooperation modes, amplify-and-forward and decode-and-forward, are introduced for cooperative communication among D2D users and relay nodes.

Device-to-device communications in cellular networks

IEEE Communications Magazine, 2014
Device-to-device communications enable two proximity users to transmit signal directly without going through the base station. It can increase network spectral efficiency and energy efficiency, reduce transmission delay, offload traffic for the BS, and alleviate congestion in the cellular core networks.

Device-to-device communication for 5G

2017
Fourth generation (4G) communication technology was introduced to accommodate the rising demands of mobile user equipments (UEs) in terms of data rates and network reliability. However, a sharp rise in the number of mobile users has resulted in recent years and is expected to grow exponentially in the years to come, which prompted the need for a ...

Device-to-Device Communications Underlaying Cellular Networks

IEEE Transactions on Communications, 2013
In cellular networks, proximity users may communicate directly without going through the base station, which is called Device-to-device (D2D) communications and it can improve spectral efficiency. However, D2D communications may generate interference to the existing cellular networks if not designed properly.

Incentive mechanisms for device-to-device communications

IEEE Network, 2015
D2D communication has recently been proposed as a promising technique to improve resource utilization of cellular networks by offloading the traffic through base stations to local direct links between devices. While various optimization frameworks have been intensively studied, little attention has been given to how to attract users to adopt D2D ...
