A key distinguishing feature of these algorithms is how aggressive or persistent they are in initiating transmission. A more aggressive algorithm may begin transmission more quickly and utilize a greater percentage of the available bandwidth of the medium. This is typically at the expense of an increased likelihood of collision with other transmitters. dance with my pants crazy rockerz

"WebThe performance of CSMA protocols with perfect carrier-sensing was analyzed in depth in [3]. The effect of carrier-sense imperfections on the throughput of non-persistent and 1-persistent CSMA protocols was ﬁrst studied in [4], [5] and p-persistent CSMA in [6]. The analytical model in the above " - Csma throughput
