We would like to announce the release of the SNEE sensor network query compiler/optimizer. SNEE (for Sensor NEtwork Engine) has been developed at the University of Manchester. It supports an expressive continuous, declarative query language over acquisitional streams, called SNEEql, using a software architecture that extends traditional distributed query processing techniques.
SNEEql queries are compiled into query evaluation plans (QEPs) in the form of executable nesC/TinyOS code. SNEEql QEPs currently target the TOSSIM simulator and the Avrora Mica2/MicaZ instruction-level simulator (TinyOS 1.x only). We have also run SNEE-generated QEPs on Tmote Sky motes running TinyOS 2.x, and a further release in which the generated QEPs are fit for small-scale experiments on such mote-level hardware is planned for the next few months.
