Aggregate query processing in the presence of dupli es in

In addition, when the sensing areas of sensor nodes are disjoint, the coordinator of each sensor becomes itself and we perform traditional aggregate query processing. Thus, the problem we are considering is a generalization of the traditional in-network aggregation problem.

Query Processing for Sensor Networks - Cornell University

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 in-network aggregation Section 3 , and investigate the interaction between the routing layer and the query layer Section 4 . We

Interplay of processing and routing in aggregate query

Interplay of processing and routing in aggregate query optimization for sensor networks Niki Trigoni Alexandre Guitton Antonios Skordylis Computing Laboratory, University of Oxford, Oxford OX1 3QD, UK Abstract. This paper presents a novel approach to processing continuous aggre-gate queries in sensor networks, which lifts the assumption of tree

Data Aggregation in Wireless Sensor Network: A Survey

Wireless sensor networks WSNs consist of sensor nodes. These networks have huge appli ion in habitat monitoring, disaster management, security and military, etc. Wireless sensor nodes are very small in size and have limited processing capability very low battery power. This restriction of low battery power makes the sensor network

Aggregate Query Processing In Peer To Peer Networks

Recommended Aggregate Query Processing In Peer To Peer Networks. aggregate quarry processing sensor networks. Improving Search in PeertoPeer Networks. Improving Search in PeertoPeer Networks,network nodes spend processing resources ie cycles to forward the query process it etc and bandwidth to send and receive messages The main cost of queries are therefore bandwidth and processing Since the

PDF Interplay of Processing and Routing in Aggregate Query

The TinyDB 8,9 and Cougar 14,15 projects investigate tree-based routing and scheduling techniques for processing aggregate queries like avg, count, sum, min and max in sensor networks. The concept of semantic routing trees SRTs 9 is used to forward queries only to children that satisfy the query predi e.
