- KonferenzbeitragHybrid push-pull query processing for sensor networks(Informatik 2004, Informatik verbindet, Band 2, Beiträge der 34. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2004) Trigoni, Niki; Yao, Yong; Demers, Alan; Gehrke, Johannes; Rajaraman, RajmohanA 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.
