Many events in real world are often correlated on a complex spatio-temporal level whereby they are manifested via observations over time and space proximities. In order to predict events in these spatio-temporal observations, the prediction model should be capable of modeling co-dependencies between data observed at various locations. In this paper, we propose a Dynamic Bayesian Network (DBN) with such spatio-temporal event prediction capability in sensor networks deployed for sensing environmental data. More specifically, we develop a DBN model with mixture distribution and a novel learning algorithm, for water level data prediction for different canals, using rainfall data at multiple locations. Experiments on real data demonstrates that our model and training method can provide accurate event prediction in real time for spatio-temporal sensor networks. © 2013 IEEE.||Source Title:||Proceedings - IEEE International Conference on Distributed Computing in Sensor Systems, DCoSS 2013||URI:||http://scholarbank.nus.edu.sg/handle/10635/83710||DOI:||10.1109/DCOSS.2013.49|
