Zusammenfassung
A powerful database abstraction for sensor networks has recently emerged in which clients program the sensors using a declarative query language. Existing work assumes that data is either pushed from sensor nodes to a gateway, or data is pulled from the gateway through queries. We show that hybrid push-pull data dissemination outperforms the pure approaches and offers significant energy savings.
