This paper presents a scheme, named D2D-assisted Multimedia Streaming (DAMS), for
selecting relay nodes to assist low-battery active users in a cellular network. The scheme …

This paper considers the power allocation problem in device-to-device (D2D)
communication underlaying a cellular network and investigates the impact of different …

Next-generation cellular networks need to provide seamless connectivity with higher data
rates, increased capacity, and enhanced network coverage. As multimedia service demands …

As one of the key technologies for the fifth generation (5G) wireless networks, device-to-
device (D2D) communications allow user equipment (UE) in close proximity to communicate …

In this paper, a Stackelberg game based power control framework is proposed for
interference coordination among device-to-device (D2D) communications and spectrum …

In a traditional cellular network, the base station (BS) plays a critical role in linking devices
for communications, but the huge user demand, especially in cities, has become a cost …

The approach of factor-graphs (FGs) is applied in the context of power control and user
pairing in Device-to-Device (D2D) communications as an effective underlay concept in …

In cellular networks, proximity users may directly communicate with each other without going
through the base station. That is called Device-to-Device (D2D) communication. It has the …

With device-to-device (D2D) based relay-assisted communications, deep faded cellular
users (CUs) get a better connectivity. The deep faded CU's achievable throughput of the link …

Abstract Device-to-device (D2D) communications provide an effective way to improve local
services in cellular networks which allow close-by users to communicate directly …
