Abstract
The SNEE query optimizer enables users to characterize data requests against wireless sensor networks (WSNs), using a declarative query language called SNEEql (SNEE for Sensor NEtwork Engine, described in [GBG+11], and publicly available at http://code.google.com/p/snee ). Queries are compiled into imperative query execution plans, which are translated into executable nesC source code. In this paper, we illustrate the lifecycle of a SNEEql query Q for in-network execution. This lifecycle encompasses the steps of preparatory metadata collection, followed by the compilation of Q into a query execution plan QEP, the dissemination of binary images implementing QEP throughout the WSN, and the generation of query results. © 2011 Springer-Verlag.
