Abstract

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 detects congestion by using packet queueing delay, and control network congestion by setting a congestion detection threshold. The simulation results in ns-2 shows that the algorithm can get good performance.
