On ASER Analysis of Energy Efficient Modulation Schemes for a Device-to-Device MIMO Relay Network

open access: yesIEEE Access, 2020
In this paper, we investigate the performance of a device-to-device (D2D) multiple-input and multiple-output (MIMO) communications using an amplify-and-forward relaying for various energy-efficient modulation schemes.

Device-to-Device Secure Coded Caching

open access: yesIEEE Transactions on Information Forensics and Security, 2020
This paper studies device to device (D2D) coded-caching with information theoretic security guarantees. A broadcast network consisting of a server, which has a library of files, and end users equipped with cache memories, is considered. Information theoretic security guarantees for confidentiality are imposed upon the files.

Spectrum Sharing for Device-to-Device Communication in Cellular Networks

open access: yes, 2014
This paper addresses two fundamental and interrelated issues in device-to-device (D2D) enhanced cellular networks. The first issue is how D2D users should access spectrum, and we consider two choices: overlay (orthogonal spectrum between D2D and cellular
