A Dynamic Queue Management Algorithm for IEEE 802.11e EDCA Wireless LAN

IEEE802.11e Enhanced Distributed Channel Access (EDCA) standard classifies data traffic into different priorities to support varying QOS requirements, each Access Category (AC) has its own buffer queue and values of EDCA parameters. However, the method to manage AC buffer queues is static and not adaptive, when traffic of different AC are not balanced, it will result in unnecessary transmission delay and packet losses, when traffic is heavy, QoS requirements of some high priority services will not be meet.
