Abstract
We develop new scheduling algorithms for the IEEE 802.16d based broadband wireless access system, in which radio resources of both time and frequency slots are dynamically shared by all users. Our objective is to provide a fair and efficient allocation to all the users to satisfy their quality of service. IEEE 802.16 based wireless access scheme(commonly known as WiMAX) is considered as one of the most promising wireless broadband access for communication networks in metropolitan areas today. Since this broadband wireless access system defines the concrete quality of service(QoS) requirement, a fair scheduling(FS) scheme is necessary to meet the QoS requirements. Many Scheduling schemes have been proposed earlier with the purpose of throughput optimazation and fairness enhancement. Here we present FS to derive its performance bounds. Our analysis demonstrates that FS support the delay requirement.This scheduler proposes a new scheduling scheme reflecting the delay requirement of rtps connections with respect to the various nrtps connections to achieve the optimal QoS requirement, without the excessive resource consumption since it 1) achieves low average as well as maximum delay for low-throughput applications 2) provides fairness regardless of variation in server capacity3) is computationally efficient.
