The Binary Exponential Backoff (BEB) used in the IEEE 802.11 MAC protocol uses a uniform random distribution to choose the backoff value. This often leads to reducing the effect of window size increment. This paper analyzes some basic aspects of backoff algorithms. Moreover, the studied aspects are used to modify existing backoff algorithms. Simulations are conducted to analyze the modified algorithms and to study the effect of modifications made.</ABSTRACT></RECORD></RECORDS></XML>
