TO-DCF, a new backoff scheme for 802.11, has\nthe potential to significantly increase throughput in dense\nwireless LANs while also opportunistically favouring nodes\nwith heavier traffic loads and/or better channel conditions.\nIn this paper we present an analytical model to investigate\nthe behaviour and performance of the TO-DCF protocol\nwith regards to operating parameters such as the number\nof nodes, the contention window size and the backoff\ncountdown probabilities.We then compare numerical results\nfrom an implementation of our model with simulations. Our\nmodel shows a high level of accuracy, even when the model\nassumptions are relaxed, and provides guidance for network\noperators to correctly configure the weight functions for\nnodes running TO-DCF given the network�s operating conditions.
