In this work, we propose and analyze a backoff enhancement for IEEE802.11 DCF that is quasi-optimal under all traffic loads. First, we give a new analysis of DCF scheme under finite load conditions in single hop configuration and we provide an accurate delay statistics model that consider the self-loop probability in every backoff state. Then we introduce the constant-window backoff scheme and we compare its performance to IEEE802.11 DCF with Binary exponential backoff. The quasi-optimality of the proposed scheme under all traffic loads is illustrated and numerical results show that it increases both the throughput and fairness of IEEE 802.11 DCF while remaining insensitive to traffic intensity.
