Robust and Efficient Aggregate Query Processing in ...08/05/2008 · Wireless sensor networks have been widely used in many environmental monitoring appliions [].In most of these appliions, aggregate queries, such as SUM, COUNT, AVERAGE (AVG), MIN and MAX, are often used as statistics collected from sensors [12, 13, 22].However, it is known that data collected from sensors are often noisy for various reasons, such as sensing device .
Interplay of Processing and Routing in Aggregate Query ...05/01/2008 · This paper presents a novel approach to processing continuous aggregate queries in sensor networks, which lifts the assumption of treebased routing. Given a query workload and a specialpurpose gateway node where results are expected, the query optimizer exploits query correlations in order to generate an energyefficient distributed evaluation plan. The proposed .
aggregate query processing sensor networksQuery Processing for Sensor Networks. we introduce our model of a sensor network, sensor data, and the class of queries that we consider in this paper. We then demonstrate our algorithms to process simple aggregate queries with innetwork aggregation (Section 3), and investigate the interaction between the routing layer and the query . GET PRICE; Interplay of processing and routing in ...
IJA: An Efficient Algorithm for Query Processing in Sensor ...Thus query processing over the nodes should be constrained because of their limitations. Due to the problems, the join operations in sensor networks are typically processed in a distributed manner over a set of nodes and have been studied. By way of example while simple queries, such as select and aggregate queries, in sensor networks
The Design and Evaluation of a Query Processing ...regarding query processing in sensor networks were a tremendous help. Thanks also to John Chuang for his helpful comments and feedback on this dissertation and for taking time out of his schedule to serve on my committee. Annie Abramson has been wonderfully caring and understanding throughout my graduate career, and especially during the past few months. I am unspeakably happy to have met her ...
