CSMA/CA performance under high traffic conditions: throughput …

WebCSMA to maximize throughput. Collisions were introduced in [7] in the Markov model, and the mean transmission length of the packets are used as the control variable to maximize the throughput. Since most applications experience random length of packets, the transmission rates (packets/unit time), http://web.mit.edu/modiano/www/6.263/L12.pdf Variations of CSMA use different algorithms to determine when to initiate transmission onto the shared medium. 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. biotechnology graduate programs indiana
