A complete data aggregation function, such as COUNT, MIN, MAX, SUM, and AVERAGE, is deployed to ensure that every packet has the same size [2].
The main challenge for data aggregators is if the aggregation functions can be accurately computed using the summarization data instead of the raw data.
To bridge this gap, in this paper we present an approach for dynamic secure end-to-end data aggregation with privacy function, named DyDAP.
Currently, the data pipeline architecture incorporates simple aggregation functions for time-series data—(1) daily average, (2) monthly average, and (3) annual average.
Once the selfish nodes are detected, their neighbors can use this information to avoid cooperating with them, either for data forwarding, data aggregation, or any other cooperative function.
Thirteen high-level features are generated from three categories (film details, reviews, and user profiles) using aggregation functions, and the data is further quantified using the description set.
While the participants had all been familiar with SPSS, many had difficulty in using it for CHA data analysis that may require functions such as data aggregation and case selection, which are not often used during standard statistical analysis.
The cluster head applies aggregation functions to squeeze the data before transmission to the destination.
An active fund manager indicated that it needed proxy advisors for their independent research function, workflow management and data aggregation.
This section presents details of implementation and functioning of the proposed data aggregation and multiplexing scheme.
As responses travel towards the root, developer-specified aggregation functions may be applied to data at each hop.
