Improving wireless physical layer security via cooperating relays
Physical (PHY) layer security approaches for wireless communications can prevent eavesdropping without upper layer data encryption. However, they are hampered by wireless channel c...

Cross-layer optimization frameworks for multihop wireless networks using cooperative diversity
We propose cross-layer optimization frameworks for multihop wireless networks using cooperative diversity. These frameworks provide solutions to fundamental relaying problems of de...

Packet level performance analysis in wireless user-relaying networks
In this paper, the impact of user relaying on the behavior of a relay node, which acts as the source node at the same time, is analyzed in a wireless relay network at the packet le...

Best-effort cooperative communication without dedicated relays
Traditional decode-and-forward cooperation systems consider dedicated relays, while instead we consider wireless transceivers that cooperatively relay signals in addition to prima...
