Congestion is regarded as one of the main reasons for the performance decrease in wireless networks,which exists in 802.16 wireless networks too. To control congestion better, this paper proposes an active queue management (AQM) algorithm named WDBQ (Wireless Delay-Based Queue) according to the characteristic of 802.16 wireless networks. The algorithm(More)
