Poster Abstract: Routing and Processing Multiple …

We present a novel approach to processing continuous aggregate queries in sensor networks, which lifts the as-sumption of tree-based routing. Given a query workload and a special-purpose gateway node where results are ex-pected, the query optimizer exploits query correlations in order to generate an energy-efcient distributed evaluation plan.
