Multi-hop ad hoc networks may employ cooperative communication, in which opportunistic relays use the spatial diversity of radio channels to increase communication reliability. An emerging variant of traditional relaying and forwarding schemes is the …
In wireless networks, stations can improve their received quality of service (QoS) by handling packets of source flows with higher priority. Additionally, in cooperative relay networks, the relays can handle transit flows with lower priority. We use …
In IEEE 802.11 networks, selfish stations can pursue a better quality of service through selfish MAC-layer attacks. Such attacks are easy to perform, secure routing protocols do not prevent them, and their detection may be complex. Two-hop relay …
Current communication standards and systems are not prepared for their application in unpredictable (lossy) environments. We present CLF-MAC - a new MAC protocol supporting the concepts of lossy forwarding and joint decoding, which implements channel …
We present in this paper a MAC layer protocol capable to cope with lossy links in interference-prone wireless environments. Our approach exploits the recent advances in information theory and physical layer coding by relaying at intermediate nodes …
