Before revision:  On the basis of this , succinct equations describing the backoff distribution as a function of the collision probability \gamma are derived . In addition, the observation that the  entropy of the backoff process in 802.11 increases with the number of nodes leads us to see through a Poissonian character inherent in 802.11.
After revision:  On the basis of this , succinct equations describing the backoff distribution as a function of the collision probability \gamma are derived , which also correct a possible misunderstanding in the field. The observation that the  entropy of the backoff process in 802.11 increases with the number of nodes leads us to see through a Poissonian character inherent in 802.11.
