Cyber physical systems have grown exponentially and have been attracting a lot of attention over the last few years.

To retrieve and mine the useful information from massive amounts of sensor data streams with spatial, temporal, and other multidimensional information has become an active research area.

Moreover, recent research has shown that clusters of streams change with a comprehensive spatial-temporal viewpoint in real applications.

In this paper, we propose a spatial-temporal clustering algorithm (STClu) based on nonnegative matrix trifactorization by utilizing time-series observational data streams and geospatial relationship for clustering multiple sensor data streams.

Instead of directly clustering multiple data streams periodically, STClu incorporates the spatial relationship between two sensors in proximity and integrates the historical information into consideration.

Furthermore, we develop an iterative updating optimization algorithm STClu.

The effectiveness and efficiency of the algorithm STClu are both demonstrated in experiments on real and synthetic data sets.

The results show that the proposed STClu algorithm outperforms existing methods for clustering sensor data streams.
