Metrics for situational awareness using sensor networks
Valentino Crespi, George V. Cybenko · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2005
In this paper we describe metrics related to the quantification of situational awareness of surveillance systems based on sensor networks. Our work emphasizes the necessity for the sensor system to be able to track processes that evolve in general stochastically and may even be driven by intelligence. The result is a hierarchical model for surveillance systems in which different levels of description of the system's state and its kinematics correspond to different levels of situational awareness and require the activation of different sensor modalities.
