School of IT Building, Lecture Theater Room 123, Level 1


Sensor networks have emerged as an exciting technology for a wide range of important applications that acquire and process information from the physical world. Sensor grids extend the paradigm of grid computing to the sharing of sensor resources in sensor networks. A sensor grid integrates sensor networks with computational and storage resources.

A key ingredient for the wide spread adoption of sensor networks is the cyber-sensor infrastructure for the efficient collection and management of data from distributed and diverse sensors and other information sources. This infrastructure addresses the collection, processing, visualization, archival, and searching of vast amounts of sensor data.

In this talk, I will first explain the relevance of sensor grids as an enabling technology for the next generation cyber-sensor infrastructure.

I will present the key issues and challenges in the design of sensor grids. We address these design issues in a sensor grid architecture that we have developed. At present, we are building the National Weather Sensor Grid, a large-scale sensor grid connecting hundreds of mini weather stations deployed in school throughout Singapore. I will highlight the design and implementation of this sensor grid.
