network processing of the aggregation queries on the data generated in the sensor network. We use the adhoc query routing algorithm of TAG to disseminate our query into the network. Our spatial aggregate operators are compatible with the aggregate processing of TAG and easily portable to TinyDB. Zhao et al. in [9] introduce an architecture for ...

In this paper, we propose an adaptive innetwork aggregation operator for query processing in sensor nodes of a WSN, called ADAGA (ADaptive AGgregation Algorithm for sensor networks). The ADAGA adapts its behavior according to memory and energy usage by dynamically adjusting datacollection and datasending time intervals.

 · Data aggregation can be done using 4 techniques following an efficient path. 1. Innetwork Aggregation: This is a general process of gathering and routing information through a multihop network. 2. Treebased Approach: The tree based approach defines aggregation from constructing an aggregation tree.

should be processed and aggregated within the network and only processed and aggregated information is returned [13, 16]. In such a setting, certain nodes in the sensor network, called aggregators, collect the raw information from the sensors, process it locally, and reply to the aggregate queries of a remote user. However, information ...

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 .

Data aggregation is any process whereby data is gathered and expressed in a summary form. When data is aggregated, atomic data rows typically gathered from multiple sources are replaced with totals or summary statistics. Groups of observed aggregates are replaced with summary statistics based on those observations.

Methods, systems, and media for aggregating and processing product information are disclosed. Embodiments include hardware and/or software for receiving an electronic receipt from a merchant that describes a transaction for a product by a purchaser and gathering product information from one or more sources such as the merchant, the product's manufacturer, the .

 · Time intervals for data aggregation process: Reporting period: The period in which the data is collected for presentation. It can either be a data point aggregated process or simply raw data. The data is collected and processed into a summarized format in a period of one day from a network device. Hence the reporting period will be one day.

 · Log aggregation is the process of collecting, standardizing, and consolidating log data from across an IT environment in order to facilitate streamlined log analysis. Without log aggregation, developers would have to manually organize, prepare, and search through log data from numerous sources in order to extract useful information from it.

Abstract. To process aggregation queries issued through different sensors as access points in sensor networks, existing algorithms handle queries independently and perform innetwork aggregation only at the query time. As a result of adhoc and independent execution of queries, no partial result is sharable and reusable among the queries.
