Abstract
The IEEE 802.15.3 standard does not specify how to schedule CTA (Channel Time Allocation)s in CTAP (Channel Time Allocation Period) of a superframe. In this paper, we propose a novel scheduling algorithm for channel time allocation of 802.15.3-based HR-WPAN (High Rate Wireless Personal Area Networks), named WFCTA (Weighted Fair Channel Time Allocation). The proposed WFCTA inherently has properties which are necessary for various QoS provisioning, because it is based on TDMA, applied by WFQ algorithm. We explain and compare four implementation cases of WFCTA. We also analyze its worst-case performance in terms of both link utilization and fairness and verify it by simulation.
This research has been conducted by the Research Grant of KwangWoon University in 2004 and by CUCN (Center of Excellence in Ubiquitous Computing and Networking).
