Performance analysis of the link selection for secure device-to-device communications with an untrusted relay

In this paper, we study the performance of the selection combining and switch and stay combining methods in secure cooperative device-to-device (D2D) communications underlying a cellular network where an untrusted amplify and forward relay helps D2D communications. In our model, we specifically consider the interference from the cellular system over the D2D pair and the interference from the D2...

Performance Analysis of Device to Device Communications Overlaying/Underlaying Cellular Network

Minimizing the outage probability and maximizing throughput are two important aspects in device to device (D2D) communications, which are greatly related to each other. In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipat...

Social-Aware Relay Selection for Cooperative Multicast Device-to-Device Communications

The increasing use of social networks such as Facebook, Twitter, and Instagram to share photos, video streaming, and music among friends has generated a huge increase in the amount of data traffic over wireless networks. This social behavior has triggered new communication paradigms such as device-to-device (D2D) and relaying communication schemes, which are both considered as strong drivers fo...

Performance analysis of device-to-device communications underlaying cellular networks

Device-to-device (D2D) communications underlaying cellular networks are considered to be promising communication modes to improve network radio resource efficiency and provide higher transmission data rates to devices close to each other. However, when D2D communications reuse cellular resources, the resulting interference will cause significant performance loss to cellular users. In this paper...
