Historic Queries in Geosensor Networks
نویسندگان
چکیده
This paper addresses—to our knowledge, for the first time—the problem of querying a geosensor network—a sensor network of mobile, locationaware nodes—for historical data. It compares different network architectures and querying strategies with respect to their performance in reconstructing events or processes that happened in the past, trying to support the hypothesis that reconstruction is possible within the limited capacities of a geosensor network only. In a concrete case study, these queries are studied in a simulated peer-to-peer ride

Queries for historic events in geosensor networks
Mining for historic data is relevant to study the behavior of complex systems. This paper addresses the problem of querying a geosensor network for historical data. Geosensor networks—sensor networks of mobile, location-aware nodes—are typically deployed for real-time observations and local analysis. This paper’s interest is in reconstructing historic states or events. The problem is relevant i...
متن کاملGeorouting and Delta-gathering: Efficient Data Propagation Techniques for GeoSensor Networks
We consider the issue of query and data propagation in the context of geosensor networks over geo-aware sensors. In such networks, techniques for efficient propagation of queries and data play a significant role in reducing energy consumption. Georouting is a new technique for the broadcasting of localized data and queries in geo-aware sensor networks; it makes use of the existing query routing...
متن کاملAmbient Spatial Intelligence
Computing in distributed systems increasingly occurs somewhere, with that location being integral to computational process itself. Ambient spatial intelligence (AmSI) is concerned with embedding the intelligence to respond to spatiotemporal queries and monitor geographical events in built and natural environments. The emergence of AmSI is enabled by new spatial computing technology: geosensor n...
متن کاملGeosensor Data Abstraction for Environmental Monitoring Application1
Environmental observation applications are designed for monitoring phenomena using heterogeneous sensor data types and for providing derived and often integrated information. To effectively handle such a large variety of different sensors, both in scale and type and data volume, we propose a geosensor abstraction for large-scale geosensor networks. Our SGSA(Slope Grid for Sensor Data Abstractio...
متن کاملDecentralized environmental simulation and feedback in robust geosensor networks
Environmental simulation and modeling has become a basic tool for scientific exploration of complex natural systems. Geosensor networks are an emerging technology for spatiotemporal monitoring of natural systems. This paper investigates the potential for embedding environmental simulations in geosensor networks, with the aim of increasing system robustness to both sensor and model errors. The a...
