Modeling DRX for D2D Communication

IEEE Internet of Things Journal, 2021
Discontinuous reception (DRX) has been included in 4G-LTE as the main power saving mechanism for user equipment (UE). However, the existing 3-state DRX model is not sufficient for new use cases introduced by 4G and 5G. For example, the device discovery process in device to device (D2D) communication has a significant impact on delay and power ...

A Design of D2D-Clustering Algorithm for Group D2D Communication

2020
Due to the characteristics of low latency and proximity discovery, D2D communication is considered to have an inherent advantage in supporting Internet-of-Vehicles (IoV) service. In this paper, considering that vehicular users can detect neighbor nodes in adjacent areas which are able to maintain high reliable communication with themselves, a novel ...

D2D Covert Communications With Safety Area

IEEE Systems Journal, 2021
In this article, we investigate device-to-device (D2D) relay enabled covert communications. Safety zone is employed to isolate the eavesdroppers from the transmitters and receivers. Different from majority of the existing studies considering fixed relays, dynamic relay selection is first considered for covert communications in this article ...

Impact of Shadowing in D2D Communication

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
Device-to-device (D2D) communication is expected to increase the coverage probability by coexisting along with the conventional cellular systems in 5G technology. As the user equipments are often held closer to the human body, D2D links experience shadowing modelled by the amp;#954;-amp;#956; shadowed fading model.
