Transmission Sequence Adjustment Scheme for Improving Fairness in Wireless LANs

In a wireless LAN, multimedia traffic is one of important traffic types. However, it is not easy to transmit multimedia traffic in a wireless LAN because it requires strict assurance for delay and loss. Although a multimedia packet is sent to a receiver without an error, it is discarded, if it does not satisfy its own delay bound. In a wireless LAN, a packet is transmitted with a First-In First-Out (FIFO) queue, i.e., a packet is transmitted in sequence regardless of delay bound of each packet. Therefore, traffic with long delay bound has good performance, though traffic with short delay bound shows poor performance.
