A Novel Power-Efficient Middleware Scheme for Sensor Grid Applications

Sensor grid deployments integrate wireless sensor networks (WSNs) and Grid Computing (GC) into a merged platform. A middleware architecture is a prerequisite for sensor grids in order to bridge the two heterogeneous technologies and efficiently support aggregated grid services available to a large number of grid users. On the other hand, the energy conservation of the participating sensor nodes is an essential factor for QoS provisioning, thereby extending WSNs survivability and providing diversity to potential grid services. For the best of our knowledge, power awareness for middleware architectures for sensor grids has never been studied in the literature so far. The rationale of our work employs a scheduler which provides QoS to the grid users from an energy awareness perspective by interacting with an appropriate resource manager. Our simulations show the effectiveness of the proposed scheme whereas a proxy-based middleware for sensor grids has been adapted.
