    Conclusions and Future WorkThis paper shows the interplay of routing and processing in evaluating aggregate queries in sensor networks, and proposes two novel algorithms that significantly outperform the existing approach. STG exploits the new concept of segmentbased aggregation, and offers up to 60% energy savings compared to NoOptimization. STS, which avoids sending query subaggregates ...

  • Adaptive spatial window aggregation query processing ...

     · Users of wireless sensor networks (WSNs) often submit spatial window aggregation queries to obtain the summary information about a local area in the monitored region. We propose an adaptive spatial window aggregation query processing algorithm called ASWAP in this paper. It divides the query area into several disjoint sub–regions. A cluster head node is elected in each .

    Wireless sensor networks (WSNs) have received increasing attention in the past decades. Owing to an enhancement of MEMS technology, various types of sensors such as motion detectors, infrared radiation detectors, ultrasonic sensors (sonar), and magnetometers can detect the objects within a certain range. Under such an environment, an object without an identifier can be detected by several ...

    200881gate queries over sensor networks in an energyefcient manner. From the databases perspective innetwork aggregation provides a mechanism for evaluating aggregate queries over sensor networks. The common approach to aggregate query processing in sensor networks has two phases the dissemination phase and the aggregation phase.
