Sensor network query processor

A Sensor Network Query Processor (SNQP), also so called sensorDB, is a user-friendly interface for programming and running applications translates instructions from declarative programming language with high-level instructions to low-level instructions understood by the operating system. Indeed, the basic idea of SNQP is the addition of a layer modeling the WSN as a distributed database searchable by a query language similar to SQL.[1][2]
Examples Of Applications
TinyDB
TinyDB is a query processing system for extracting information from a network of TinyOS sensors. Unlike existing solutions for data processing in TinyOS, TinyDB does not require you to write embedded C code for sensors. Instead, TinyDB provides a simple, SQL-like interface to specify the data you want to extract, along with additional parameters, like the rate at which data should be refreshed -- much as you would pose queries against a traditional database. [3] Given a query specifying your data interests, TinyDB collects that data from motes in the environment, filters it, aggregates it together, and routes it out to a PC. TinyDB does this via power-efficient in-network processing algorithms.
