When the network abnormal event occurs, the spatial-temporal correlation of the sensor nodes is very obvious.While existing methods generally separate time and space data properties, a decentralized algorithm of spatial-temporal abnormal detection based on Probabilistic Graphical Model(PGM) was proposed. Firstly the Connected Dominating Set(CDS)algorithm was used to select part of the sensor nodes to avoid monitoring all the sensor nodes, and then Markov Chain(MC)was used to predict time exception event, at last Bayesian Network(BN) was utilized in modelling the spatial dependency of sensors, combining spatio-temporal events to predict whether the abnormal events would or would not occur. Compared with the simple threshold algorithm and BN algorithm, the experimental results demonstrate that the proposed algorithm has higher detection precision, and low delay rate, greatly reducing the communication overhead and improving the response speed.
