Aggregate query processing in the presence of duplicates,
Mar 10, 2015· 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.Wavelet-Based Least Common Ancestor Algorithm for,,Jan 03, 2021· Wireless sensor network (WSN) is developed as a network of sensors, which engage in sensing and transmitting the data to the sink node. The constraints, such as energy, memory, and bandwidth insist the researchers to develop an efficient method for data transmission in WSN. Accordingly, this paper introduces a data aggregation mechanism based on query processing,Processing approximate aggregate queries in wireless,,Dec 01, 2006· The development of powerful and inexpensive sensors in recent years has spurred a flurry of research in the area of sensor networks, with particular emphasis in the topics of network self-configuration , data discovery , , distributed data storage , , , energy efficient data routing , and in-network query processing , , , .TinyCasper: A Privacy-Preserving Aggregate Location,,niques designed for wireless sensor networks.

Assembling Regions for Efficacious Aggregate Query,
1.1 Query answering in sensor networks Sensor networks answer queries by finding the nodes which collect the relevant information and by combining their observations. This requires that data has to be propagated to the node, which will produce the answer. A sensor network is a pervasive computing environment, which has to manage its resources.CiteSeerX — Routing and Processing Multiple Aggregate,,This paper presents a query-driven approach to routing and processing continuous aggregate queries in sensor networks. 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 energyefficient distributed evaluation plan.TinyCasper: A Privacy-Preserving Aggregate Location,,niques designed for wireless sensor networks.
