Processing Approximate Aggregate Queries In Wireless

Processing approximate aggregate queries in wireless sensor networks While the nodes in sensor networks form an aggregation tree where messages are aggregated and therefore Y. Yao J. GehrkeThe Cougar approach to in

Interplay Of Processing And Routing In Aggregate Query

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 optimier exploits query correlations in order to generate an energy

Poster Abstract Routing and Processing Multiple Aggregate Queries in Sensor Networks Niki Trigoni Alexandre Guitton Antonios Skordylis Birkbeck College University of London London WC E 7HX United Kingdom fnikialexandreadonisgdcs.bbk.ac.uk Abstract We present a novel approach to processing continuous aggregate queries in sensor networks

Tinycasper A Privacy

Niques designed for wireless sensor networks. On the other side the aggregate query processing module is embedded inside the server to support aggregate query processing over anonymied lo ions. TinyCasper system administrators can change the privacy requirement i.e. kanonymity requirement at anytime. Finally system users can issue snap

A Privacy

This end we propose a privacypreserving lo ion monitoring system for wireless sensor networks. In our system we design two innetwork lo ion anonymiation algorithms namely resource and quality

Aggregate Query Processing In Wireless Sensor Networ

Processing approximate aggregate queries in wireless sensor networks While the nodes in sensor networks form an aggregation tree where messages are aggregated and therefore the number of transmitted messages depends on the tree topology assumes a flat setup of the remote data sources where the cost of transmitting a message from each source

Robust And Efficient Aggregate Query Processing In

Wireless sensor networks have been widely used in many appli ions such as soil temperature monitoring for plant growth and abnormal event detection of industrial parameters. Among these appli ions aggregate queries such as SUM COUNT AVERAGE MIN and MAX are often used to collect statistical data. Due to the low quality sensing devices or random environmental disturbances sensor
