There have been several compensation mechanisms proposed for fair queueing algorithms. Mobile stations which are unable to transmit due to bad channel condition will get compensated after their channel conditions are recovered. However, compensation after channels are recovered could possibly cause unnecessary extra waiting time on channel recovery or reconnection. In this paper, we will propose a new compensation model with channel prediction. Channel conditions are mainly affected by location-dependent errors. Therefore, prediction for channel condition can be done by simply predicting users’ locations. Based on location prediction, we compensate users before they suffer from location-dependent errors and poor channel conditions. Through simulations we show that our compensation method with location prediction provides better performance in packet loss probability and mean delay.
