Using active queue management to enhance performance in IEEE802.11
Gianluigi Pibiri, Ciarán McGoldrick, Meriel Huggard · 2009
Active Queue Management (AQM) is most commonly used in wired networks, principally in backbone routers where packet loss is due to network congestion. In this work we extend AQM to wireless networks. In particular, a new priority queue algorithm is introduced which helps to manage both control and routing packets in the wireless network. This priority queue algorithm offers an improvement in QoS for some services; specifically for TCP traffic and real time services that are sensitive to the loss of control and routing packets. Key AQM schemes (RED, REM, AVQ, Blue and RIO) are extended to incorporate the priority queue algorithm. The behaviour and performance of the augmented schemes is then examined through simulation.
