Abstract :
This paper proposes TD-uCSMA a synchronous distributed coordination function which is meant to provide CSMA/CA with a mechanism for QoS provisioning and bandwidth management over WiFi networks. TD-uCSMA relies on synchronization among nodes and the time-driven switching of contention parameters inside nodes. The TD-uCSMA operating principles and preliminary synchronization issues are presented here together with an extensive simulation analysis showing the effectiveness of the proposed solution.
