Add to ORKGWe give a status update of the Cougar Project, in which we investigate a database approach to sensor networks: Clients "program" the sensors through queries in a high-level declarative language (such as a variant of SQL). In this paper, we overview our activities on energy-efficient data dissemination and query processing. Due to space constraints, we cannot present a full menu of results; instead, we decided to only whet the reader's appetite with some interesting problems in energy-efficient routing and in-network aggregation and some thoughts on how to approach them
