Approximate Packet Delay Analysis for IEEE 802.16 Networks

Abstract

Supporting QoS is one of notable features in IEEE 802.16 networks. In this study, we used the queuing-theoretic approach to model the uplink air interface of IEEE 802.16 networks as M/Db/1 queues. The justification for this modeling argument was given in the paper. The average queuing delay and system delay were derived with embedded Markov chain technique. We also pointed out that the created Markov chain exhibits geometric tail behavior so that the Markov chain can be solved more efficient. The analytical results were verified through computer simulations. The derived results would be supporting the design of packet scheduling or admission control.
