Sensor network query processor - Wikipedia

A sensor network query processor (SNQP), also called a sensorDB, is a user-friendly interface for programming and running applications which translates instructions from declarative programming language with high-level instructions to low-level instructions understood by the operating system.The basic idea of SNQP is the addition of a layer modeling the WSN as a distributed database searchable

Curve Query Processing in Wireless Sensor

26-11-2014· Abstract: Most existing query processing algorithms for wireless sensor networks (WSNs) can only deal with discrete values. However, since the monitored environment always changes continuously with time, discrete values cannot describe the environment accurately and, hence, may not satisfy a variety of query requirements, such as the queries of the maximal, minimal, and inflection

Poster Abstract: Routing and Processing Multiple Aggregate

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.

A Sensor Network Data Aggregation Technique

consider the physical limitations of sensor networks [18 and 19]. In addition, the TinyDB Project at Berkeley [15] conducted by Madden et al. also investigates query processing techniques for sensor networks including an implementation of the system on the Berkeley motes and aggregation queries. The basic approach used in both

Aggregate Location Monitoring for Wireless Sensor Networks

aggregate query processor that has the ability to answer aggregate query Q that asks about the number of objects in a certain area Q.Area ∈S.Area. Wireless sensor network. In our system, we consider stationary wireless sensor nodes. Each sensor node has only the capacity to report aggregate locations to a server that contains the aggregate

[PDF] Routing and processing multiple aggregate

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