Cooperative diversity has gained much interest due to its ability to mitigate multipath fading
without using multiple antennas. There has been considerable research on how cooperative …

Providing economic incentives to all parties involved is essential for the success of dynamic
spectrum access. Cooperative spectrum sharing is one effective way to achieve this, where …

Cooperative spectrum sharing can effectively improve the spectrum usage by allowing
secondary users (SUs) to dynamically and opportunistically share the licensed bands with …

Device-to-device (D2D) cooperative relay can improve network coverage and throughput by
assisting users with inferior channel conditions to implement multi-hop transmissions. Due to …

Device‐to‐device (D2D) communication has recently attracted much research attention
because of its potential to increase the capacity of cellular networks. Most existing works aim …

By exploiting the spatial diversity of multiple wireless nodes, cooperative communication
technique is a promising technique for spectrum sharing to improve spectrum efficiency. In …

We consider a decode and forward collaborative network and investigate the relay selection
problem. Users are able to collaborate with each other; decode messages of each other, re …

Cooperative relay can effectively improve spectrum efficiency by exploiting the spatial
diversity in the wireless networks. However, wireless nodes may acquire different network …

In this work, we consider the problem of joint relay selection and resource allocation in Long
Term Evolution-Advanced (LTE-A) systems which provides both cognitive radio and relaying …

In this paper, we study a multi-cluster Wireless Powered Communication Network (WPCN)
where each cluster of users cooperate with a Cluster Head (CH) and a Hybrid Access Point …
