MHT Approach to Ubiquitous Monitoring of Spatio-Temporal Phenomena
Varun K. Garg, Thanuka L. Wickramarathne · 2018
This paper describes a multiple-hypothesis tracking (MHT) formulation of a particular set of situational awareness problems that involve monitoring of spatio-temporal phenomena using ubiquitous sensing. In particular, the focus is on large-scale monitoring (or tracking) applications utilizing volunteer mobile ubiquitous sensors to track the evolution of spatio-temporal `targets' of interest (e.g., tracking snow-fall or ride-quality at a certain stretch of a roadway using vehicles). An efficient framework is developed utilizing MHT as the basis to carry out detection and tracking of evolutionary behavior. The framework is described via an illustrative example on ride-quality monitoring as applied to autonomous driving environments, where vibration and GPS data recorded by voluntarily participating vehicles are utilized for threat detection and tracking.
