Probability Distribution Analysis Of Backoff Time With Frozen Backoff In Csma/Ca

Recently, in wireless communications a transmission rate degradation due to the increase of traffic becomes a serious problem. To deal with this problem, the number of users is an important parameter. To the estimation of the number of users, a probability distribution of backoff is applicable with the maximum likelihood approach. In this paper, an analysis method is proposed to derive the probability distribution of backoff considering frozen backoff in time axis. The analysis and simulation results are compared to show the validity the proposed method.
