Method for wireless local area network communication in distributed coordination function mode

摘要

Provided is a wireless local area network (LAN) communication method in the Distributed Coordination Function mode. The method includes (a) setting a predetermined back-off according to the characteristic of data transmitted, and (b) transmitting data if a channel is available at the end of the back-off, and updating the back-off using residual back-off when a channel is used during the back-off. The data transmission throughput can be increased by reducing the back-off according to the characteristic of data to be transmitted. An increase in the data transmission throughput is particularly effective in transmitting real-time data.
