Contention Window Optimization in IEEE 802.11ax Networks with Deep Reinforcement Learning

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 …

Impact of Lossy Forwarding on MAC and Routing Design in Wireless Ad Hoc Networks

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 …

CLF-MAC: A coordinated MAC protocol supporting Lossy Forwarding in WLANs

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 …

A cooperative MAC protocol for lossy forwarding networks

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 …
