Persistent csma

WebCSMA options differ when a station has a frame to transmit but the channel is busy – 1-persistent CSMA (most greedy) • Start transmission as soon as the channel becomes idle • Low delay and low efficiency – Non-persistent CSMA (least greedy) • Wait a backoff period, then sense carrier again • High delay and high efficiency Web26. okt 2012 · CSMA/CA và NAV. 9.
