This paper takes 802.11MAC as the research object, analyzes the basic principle of DCF protocols based on 802.11MAC and describes the performance of the CSMA/CA algorithm based on DCF protocol. CSMA/CA algorithm is the binary exponential backoff mechanism, using the minimum backoff window to transmit, backoff, retransmission so as to reduce the collision times and transmission time to realize the minimized data transmission error.
