| Summary: | 碩士 === 國立交通大學 === 電信工程系所 === 97 === For QoS (Quality of Service) requirements of real-time traffic on WLAN, IEEE 802.11 Task Group E provides HCF (Hybrid Coordination Function),which consists an contention-free access mode named HCCA(HCF control channel access) adopting polling mechanism. How to set a good schedule algorithm to decide the service interval and the TXOP duration of STAs is an important issue.
In this paper we present three multipolling algorithms, with the response mechanism, allocate the TXOP duration of STAs accurately for the real requirement. The algorithm provides better the performance of CBR and VBR traffic.
