An efficient learning technique to predict link quality in WSN

International audienceIn this paper, we apply learning techniques to predict link quality evolution in a wireless sensor network (WSN) and take advantage of wireless links with the best possible quality to improve the packet delivery rate. We model this problem as a forecaster prediction game based on the advice of several experts. The forecaster learns on-line how to adjust its prediction to better fit the environment metric values. Simulations using traces collected in a real WSN show the improvement of the prediction when the experts use the SES prediction strategy, whereas the forecaster uses the EWA learning strategy
