Abstract

IEEE 802.15.3 High-Rate WPAN(Wireless Personal Area Network) which is operated in ISM unlicensed frequency band is easily affected by channel errors. In this paper, we propose a scheduling algorithm which takes channel errors into consideration in scheduling asynchronous data traffic. The proposed scheduling algorithm can allocate CTA(Channel Time Allocation) proportionally in accordance with the requested channel time of each device. It also prevents the waste of channel time by allocating CTA of the devices that are in channel error status to other devices and preserves the fairness among the devices by compensating the channel time to the devices recovering from channel error. Simulation results show that proposed scheduling algorithm is superior to existing SRPT(Shortest Remain Processing Time) and RR(Round Robin) in throughput and fairness aspects.
