Power-Efficient Packet Scheduling Method for IEEE 802.15.3 WPAN

摘要

Power efficiency is the key issue for mobile devices, which mainly rely on limited battery power. The IEEE 802.15.3 wireless personal area network (WPAN) standard adopts a time division multiple access (TDMA) protocol controlled by a central device to support isochronous traffics. In the TDMA-based wireless packet networks, the packet scheduling algorithm plays a key role in power efficiency. However, the standard suffers from long access delay and association delay which increase the power consumption. In this paper, we propose a packet scheduling method to improve the power efficiency. Performance evaluations are carried out through simulations and significant performance enhancements are observed. Furthermore, the performance of the proposed scheme remains stable regardless of the variable system parameters such as the number of devices and superframe size.
