D2D communication motor-assisted by a cellular network brings the advantage of the proximity of wireless devices to boost reusing resources between D2D and cellular UEs, and imparts any rewards of hop gain. 3GPP started a study item on proximity-based services in D2D. SAE design for a D2D network, which incorporates the core and access, the protocol stack for D2D communication and completely di...

Device-to-device (D2D) communication is an essential part of the future fifth generation (5G) system that can be seen as a “network of networks,” consisting of multiple seamlessly-integrated radio access technologies (RATs). Public safety communications, autonomous driving, socially-aware networking, and infotainment services are example use cases of D2D technology. High data rate communication...

Device-to-device (D2D) communication is a promising approach to efficiently disseminate critical or viral information. Reaping the benefits of D2D-enabled networks is contingent upon choosing the optimal content dissemination policy subject to resource and user distribution constraints. In this paper, a novel D2D network analysis (DNA) framework is proposed to study the impacts of frequently oc...

Device-to-Device (D2D) communications underlaying cellular networks is a viable network technology that can potentially increase spectral utilization and improve power efficiency for proximitybased wireless applications and services. However, a major challenge in such deployment scenarios is the interference caused by D2D links when sharing the same resources with cellular users. In this work, ...

Several applications, from the Internet of Things for smart cities to those for vehicular networks, need fast and reliable proximity-based broadcast communications, i.e., the ability to reach all peers in a geographical neighborhood around the originator of a message, as well as ubiquitous connectivity. In this paper, we point out the inherent limitations of the LTE (Long-Term Evolution) cellul...

Public Safety Networks (PSNs) have been recognized as the key to a successful response to emergency and disaster situations. Recently, the 3GPP-LTE cellular networks open possibilities to enhance public safety services. To position the current LTE to meet the requirements of the evolution of PSNs, this paper proposes an approach to investigates the two key radio technologies, i.e., device-to-de...

This paper considers full-duplex (FD) device-todevice (D2D) communications in a downlink MISO cellular system in the presence of multiple eavesdroppers. The D2D pair communicate sharing the same frequency band allocated to the cellular users (CUs). Since the D2D users share the same frequency as the CUs, both the base station (BS) and D2D transmissions interfere each other. In addition, due to ...

The coded caching scheme is an efficient technique as a solution to reduce the wireless network burden during the peak timesin a Device-to-Device (D2D in short) communications. In a coded caching scheme, each file block should be divided into Fpackets. It is meaningful to design a coded caching scheme with the rate and F as small as possible, especially in the practice forD2D networ...

Device-to-device (D2D) communications are a promising paradigm to improve spectral efficiency in cellular wireless networks by enabling peer to peer communication. In particular, short D2D links can be used to relay data to reduce the burden on core infrastructure. However, this relies on some mechanism to either enforce or incentivise nodes to donate their resources in order to act as a relay ...
