Contention Window Based Parameter Selection to Improve Powerline MAC Efficiency for Large Number of Users

Overview Effective use of the power line bandwidth requires robust physical and Medium Access Control (MAC) protocols to mitigate the harsh conditions of the power line channel, as well as the capability to support prioritized multimedia traffic. HomePlug 1.0 is the most commonly used technology for power line communication. HomePlug 1.0 uses Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) to provide a maximum MAC data rate of 8 Mbps. Just as in 802.11, the throughput performance of this scheme becomes critical when the number of users increases, as in BPL. In this paper, a modification in the medium access control protocol of Home Plug 1.0 is proposed, to make it a constant contention window based scheme.
