Motivation

By comining the features of CSMA and TDMA, fully decentralized WLAN MAC schemes have recently been proposed that converge to collision-free schedules. In L-MAC, we introduce learning algorithms that can substantially speed up convergence of collision free operation and develop a decentralized schedule length adaptation scheme that provide long-run fair access to the medium while maintaining collision-free access for arbitrary numbers of stations. I realize the algorithm of L-MAC using Madwifi. The benefit is that only the driver is modified and no additional hardware support is necessary so the scheme can be directly applied to any current machine.
