Abstract Near the beginning of Daniel Defoe’s novel A Journal of the Plague Year (1722)—on the third page in modern editions—the narrator, H.F., introduces evidence of the arrival of the Plague in London. Late in 1664 rumours of deaths from the deadly disease had begun to spread, he recalls, and it was observed that, in four central ...

User Discovery in Device-to-Device Communications
2020 28th Signal Processing and Communications Applications Conference (SIU), 2020In 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.

In-Band Device to Device (D2D) Communication and Device Discovery: A Survey
Wireless Personal Communications, 2019Device to device (D2D) communication is one of the potentials to achieve the established standards for 5G. It represents a direct communication between two devices located in the vicinity of each other. In D2D communication, user's data traffic can be offloaded without passing through the base transceiver system (BTS) and the core network.

Authorization based on mobile whitelist in devices for device-to-device communications
2018 International Conference on Information Networking (ICOIN), 2018In mobile networking, D2D (Device-to-Device) communication extends the network beyond the reliance of existing base stations and provides a flexible data exchange. In other words, D2D allows short range communications to be collected for short range service support in a network.

IEEE Transactions on Software Engineering, 1980
A driver is the part of an I/O system used for processing of an I/O request for a specific channel. The interaction of the CPU with a channel is described through the monitor concept of Hoare and Brinch Hansen. The implementation of monitors using hardware interrupt facilities is described. The resulting device monitor is compared pared with the device

Device-to-Device Communications: A Contemporary Survey
Wireless Personal Communications, 2017Device-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

Device-to-device communications in cellular networks
IEEE Communications Magazine, 2014Device-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.

A novel approach for device-to-device transmission
2015 IEEE 5th International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 2015This paper presents a novel approach for device-to-device transmission. The proposed method has a variety of transmission modes that can be used interchangeably according to network traffic. With this method, much better overall system performance can be achieved.

Experimental Analysis of Device-to-Device Communication
2019 Twelfth International Conference on Contemporary Computing (IC3), 2019In Long-Term-Evolution-Advanced (LTE-A) cellular networks, the devices present in close proximity can communicate directly without going through the base station. This technology is known as device-to-device (D2D) communication. Higher spectral efficiency, low latency and enhanced throughput, etc.
