Geosensor Networks: State of the Art

Advances in microsensor technology as well as the development of miniaturized computing platforms enable us to scatter numerous untethered sensing devices in hard to reach terrains, and continuously collect geospatial information in never before seen spatial and temporal scales. Sensor networks deployed in geographic space to detect, monitor and track environmental phenomena are called geosensor networks. Geosensor network technologies are revolutionizing the way that geospatial information is collected, analyzed and integrated with existing large-scale sensor platforms and historical data, with the geospatial content of the information being of fundamental importance. Analysis and event detection in a geosensor network is performed in real-time within the network.

In this talk, I will present some of our current research work in the Geosensor Networks Lab at the University of Maine with regard to monitoring and tracking continuous phenomena using geosensor networks as well as in-network spatial window query estimation. Another one of our application areas is intelligent transportation and ad-hoc decision making in dynamic mobile geosensor networks as well as ocean drifter networks for red tide detection.
