To address this problem, we propose a link quality estimator which use the packet loss rate (PLR), round trip time (RTT), available bandwidth (ABW) at the sender and the feedback information from receiver to continuously tracks the channel error probability and the collision probability of the receiver by using an Unscented Kalman Filter (UKF). Through experiments we demonstrate that our link estimator can quickly adapt to the temporal dynamics of the links and accurately predict the link quality, which is more accurate than the traditional broadcasting-based method. © 2009 IEEE.||Source Title:||ICICS 2009 - Conference Proceedings of the 7th International Conference on Information, Communications and Signal Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/69186||ISBN:||9781424446575||DOI:||10.1109/ICICS.2009.5397723|
