Processing approximate aggregate queries in wireless

Dec 01, 2006 In-network data aggregation has been recently proposed as an effective means to reduce the number of messages exchanged in wireless sensor networks. Nodes of the network form an aggregation tree, in which parent nodes aggregate the values received from their children and propagate the result to their own parents.

Robust and Efficient Aggregate Query Processing in

Wireless sensor networks have been widely used in many applications, such as soil temperature monitoring for plant growth and abnormal event detection of industrial parameters. Among these applications, aggregate queries, such as SUM, COUNT, AVERAGE, MIN and MAX are often used to collect statistical data.

For monitoring queries that aggregate the observed values from a group of sensor nodes, [14] suggested the construction of a greedy aggregation tree that seeks to maximize the

Data aggregation in wireless sensor network,11751 d5811

Dec 25, 2012 The main goal of dataaggregation algorithms is to gather and aggregate datain an energy efficient manner so that network lifetime isenhanced. Wireless sensor networks (WSN) offer anincreasingly Sensor nodes need less power forprocessing as compared to transmitting data. It ispreferable to do in network processing inside networkand reduce packet
