Sensing a changing world

Second IEEE Workshop on Dependability and Security in Sensor Networks and Systems

Increasingly, space and ground sensors are being linked together to produce added value for measurements. One area of need that is emerging is in the Earth Sciences where enhanced measurements of transient science events are enabled via the use of sensor webs. This panel will examine the current state of the art and what the future holds. Furthermore, it will examine what technology gaps that ought to be filled in order achieve the future sensor web architectures that will fulfill the vision of the Global Earth Observing System of Systems (GEOSS) as agreed upon by over 60 countries at the Third Earth Observation Summit in February 2005. Panel members will discuss their experience with past experiments and outline their views about future needs. This will be followed by an open discussion with the audience.

Sensors, 2005

In 1997, the Sensor Web was conceived at the NASA/Jet Propulsion Laboratory (JPL) to take advantage of the increasingly inexpensive, yet sophisticated, mass consumer-market chips for the computer and telecommunication industries and use them to create platforms that share information among themselves and act in concert as a single instrument. This instrument would be embedded into an environment to monitor and even control it. The Sensor Web's purpose is to extract knowledge from the data it collects and use this information to intelligently react and adapt to its surroundings. It links a remote end-user's cognizance with the observed environment. Here, we examine not only current progress in the Sensor Web technology, but also its recent application to problems in hydrology to illustrate the general concepts involved.

In the recent decade, several technology trends have influenced the field of geosciences in significant ways. The first trend is the more readily available technology of ubiquitous wireless communication networks and progress in the development of lowpower, short-range radio-based communication networks, the miniaturization of computing and storage platforms as well as the development of novel microsensors and sensor materials. All three trends have changed the type of dynamic environmental phenomena that can be detected, monitored and reacted to. Another important aspect is the real-time data delivery of novel platforms today. In this paper, I will survey the field of geosensor networks, and mainly focus on the technology of small-scale geosensor networks, example applications and their feasibility and lessons learnt as well as the current research questions posed by using this technology today. Furthermore, my objective is to investigate how this technology can be embedded in the current landscape of intelligent sensor platforms in the geosciences and identify its place and purpose.

The ongoing massive global environmental changes and the past learnings have highlighted the urgency and importance of further detailed understanding of the earth system and implementation of social ecological sustainability measures in a much more effective and transparent manner. This short communication discuss the potential of sensor webs in addressing those research challenges, highlighting it in the context of air pollution issues.

Environmental monitoring faces a variety of complex technical and socio-political challenges, particularly in the urban context. Data sources may be available, but mostly not combinable because of lacking interoperability and deficient coordination due to monolithic and closed data infrastructures. In this work we present the real-time geoawareness approach that seeks to tackle these challenges with an open sensing infrastructure for monitoring applications. Our system makes extensive use of open (geospatial) standards throughout the entire process chain -from sensor data integration to analysis, and finally visualisation. Then, we show how the methodology can influence the city and its inhabitants by 'making the abstract real', in other words how pervasive environmental monitoring systems change urban social interactions, and which issues are related to establishing such systems.

open, interconnected, intelligent and dynamic network of sensors that performs extensive spatialtemporal monitoring of our environment through coordinated work between multiple types and numbers of sensor networks. With the presence of cheaper, miniature and smart sensors; high-resolution remote sensing sensors; abundant fast and ubiquitous computing devices; wireless and mobile communication networks; and autonomous and intelligent software agents, the Sensor Web has become a clear technological trend in ...

ICDE Demo 2009

A sensor network data gathering and visualization infrastructure is demonstrated, comprising of Global Sensor Networks (GSN) middleware and Microsoft SensorMap. Users are invited to actively participate in the process of monitoring real-world deployments and can inspect measured data in the form of contour plots overlayed onto a high resolution map and a digital topographic model. Users can go back in time virtually to search for interesting events or simply to visualize the temporal dependencies of the data. The system is presented not only interesting and visually enticing for non-expert users but brings substantial benefits to environmental scientists. The easily Installed data acquisition components as well as the powerful data sharing and visualization platform opens up new ground in collaborative data gathering and interpretation in the spirit of Web 2.0 applications.
