Cooperative communications with relay-selection: when to cooperate and whom to cooperate with?
Abstract--In this paper, we propose a new cooperative communication protocol, which achieves higher bandwidth efficiency while guaranteeing the same diversity order as that of the ...

Lifetime maximization for amplify-and-forward cooperative networks
Power allocation strategies are devised to maximize the network lifetime of amplify-and-forward (AF) cooperative networks in this work. We consider the scenario where one source an...

Power Allocation Based on SEP Minimization in Two-Hop Decode-and-Forward Relay Networks
—The problem of optimal power allocation among the relays in a two-hop decode-and-forward cooperative relay network with independent Rayleigh fading channels is considered. It is...

Design of Fair Weights for Heterogeneous Traffic Scheduling in Multichannel Wireless Networks
Fair weights have been implemented to maintain fairness in recent resource allocation schemes. However, designing fair weights for multiservice wireless networks is not trivial bec...

Cooperation strategies for secrecy in MIMO relay networks with unknown eavesdropper CSI
We investigate secure communications for a four-node relayeavesdropper channel with multiple data stream transmission, assuming that the eavesdropper’s channel state information...
