CAC

Author: Paul Patras

CAC is a Linux application that implements a centralized adaptive algorithm, which can be deployed on commodity access points to optimise the throughput performance of WLANs based on the IEEE 802.11 technology.

CAC targets the best-effort (BE) access category and was developed in conjunction with a modified version of the popular Madwifi driver, whereby the update of the contention parameters assigned to the BE access category was enabled. The modified driver is available at:
