Collision probability in saturated IEEE 802.11 networks

In this paper we study the impact of channel capture following a busy period on collision probabilities in a saturated IEEE 802.11 network. A new analytical model that takes into account the previous channel status is proposed to obtain collision probabilities. Using simulation, we show that the well-known fixed point analysis, which is a special case of the new model, becomes more accurate as the size of the initial backoff window increases.
