The proper setting of contention window (CW) values has a significant impact on the efficiency of Wi-Fi networks. Unfortunately, the standard method used by 802.11 networks is not scalable enough to maintain stable throughput for an increasing number …
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 …
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 …
