Data Aggregation and Query Processing in WSN. Ayoni Mukherjee, Sanjit Setua. Abstract A wireless sensor network (WSN) has a wide range of important appliions such as remote environment monitoring, target tracking etc. This has been enabled by the availability of sensors that are smaller, cheaper and intelligent.
This study proposes a method of innetwork aggregate query processing to reduce the number of messages incurred in a wireless sensor network. When aggregate queries are issued to the resourceconstrained wireless sensor network, it is important to efficiently perform these queries. Given a set of multiple aggregate queries, the proposed approach shares intermediate results among queries to ...
Jun 30, 2005 · In this paper we consider multiquery optimization for aggregate queries on sensor networks. We develop a set of distributed algorithms for processing multiple queries that incur minimum communiion while observing the computational limitations of the sensor nodes.
An important class of queries over sensor networks are networkwide aggregation queries. In this work we study a class of aggregation queries which we refer to as aggregate threshold queries. The goal of an aggregate threshold query is to continuously monitor the network and give a notifiion every time an aggregated value crosses a predetermined threshold value.

By way of example while simple queries, such as select and aggregate queries, in sensor networks have been addressed in the literature, the processing of join queries in sensor networks remains to be investigated. Therefore, in this paper, we propose and describe an Incremental Join Algorithm (IJA) in Sensor Networks to reduce the overhead ...
