Dynamic Fragmentation Scheme for Rate-Adaptive Wireless LANs

Overview Many rate-adaptive MAC protocols have been proposed in the past for wireless LANs over time-varying media to provide efficient channel usage and throughput enhancement. Most of these protocols are receiver-based and employ RTSICTS collision avoidance handshakes specified in the Distributed Coordination Function (DCF) of the IEEE802.11 MAC. However, these protocols do not consider the possible bursts transmission of fragments in a rate-adaptive fashion. In this paper, a rate-adaptive protocol with a dynamic fragmentation scheme is proposed in order to enhance the throughput by employing bursty fragment transmissions based on the channel condition.

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
