Abstract
The IEEE 802.11 backoff algorithm is very important for controlling system throughput over contentionbased
wireless networks. For this reason, there are many studies on wireless network performance focus on
developing backoff algorithms. However, most existing models are based on saturated traffic loads, which
are not a real representation of actual network conditions. In this paper, a dynamic control backoff time
algorithm is proposed to enhance both delay and throughput performance of the IEEE 802.11 distributed
coordination function. This algorithm considers the distinction between high and low traffic loads in order
to deal with unsaturated traffic load conditions. In particular, the equilibrium point analysis model is used
to represent the algorithm under various traffic load conditions. Results of extensive simulation
experiments illustrate that the proposed algorithm yields better performance throughput and a better
average transmission packet delay than related algorithms.
