Abstract
Sensor grids integrate wireless sensor networks with the grid computing infrastructure, enabling sensor resources to be shared as distributed and heterogeneous resources. By combining the complementary strengths of sensor networks and grid computing, sensor grids can support applications that require real-time sensor data from the physical environment, and vast amount of computational and storage resources.
A major challenge in the design of sensor grids is the management of sensor data from wireless sensor networks in order to efficiently provide data related services to applications. In this paper, we design a Data Management component for our sensor grid architecture. The Data Management component provides services such as data conversion, streaming and event notification to applications. We have implemented the Data Management component on a real sensor grid testbed. Our validation tests indicate that this component works well within our sensor grid testbed.
