Sensor network protocols must minimize energy due to their resource-constrained nature. Large amounts of redundant data are produced by the sensors in such networks, however sending unnecessary data wastes energy. One common technique used to reduce the amount of data in sensor is data aggregation. Therefore, we consider the impact and cost of data aggregation in sensor networks to achieve ener...

A wireless sensor network (WSN) consists of numerous sensor nodes and each node is having capable of collecting, processing, storing, and transmitting to the base station. In case of each node involves the transmission to sink node leads more energy consumption. So, a typical data reporting operation provisions the aggregation mechanism to reduce the usage of battery power. By cooperating the s...

This paper presents multidimensional aggregation query processing algorithm in cloud computing system. The existing cloud computing research work in the MapReduce calculation framework lacks effective support to the aggregation of multi-dimensional data. On the other hand, the use of MapReduce computing framework needs to start large computing nodes, and costs huge amounts of energy. For the ab...

The objective of this work is to present a triangular interval type-2 (TIT2) intuitionistic fuzzy sets and their corresponding aggregation operators, namely, TIT2 intuitionistic fuzzy weighted averaging, TIT2 intuitionistic fuzzy ordered weighted averaging and TIT2 intuitionistic fuzzy hybrid averaging based on Frank norm operation laws. Furthermore, based on these operators, an approach to mul...

Rank aggregation is a pervading operation in IR technology. We hypothesize that the performance of score-based aggregation may be affected by artificial, usually meaningless deviations consistently occurring in the input score distributions, which distort the combined result when the individual biases differ from each other. We propose a score-based rank aggregation model where the source score...

Information aggregation is one of the key issues in development of intelligent systems. Although fuzzy set theory provides a host of attractive aggregation operators for integrating the membership values representing uncertain information, the results do not always follow the modeled real phenomena. Researches on this area have shown that better results can be reached by using various aggregati...

Much information over the Internet is expressed by natural languages. The management of linguistic information involves an operation of comparison and aggregation. In this paper, based on linguistic aggregation operator Flowa, we discussed linguistic information processing in a multi-agent system over the Internet, in which, aggregating linguistic information and selecting better Web pages (or ...

In this paper, aggregation is treated as a logical and/or pseudo-logical operation what is important from many points of view such as adequacy and interpretations.

Data aggregation is an essential operation to reduce energy consumption in large-scale wireless sensor networks WSNs . A compromised node may forge an aggregation result and mislead base station into trusting a false reading. Efficient and secure aggregation scheme is critical in WSN applications due to the stringent resource constraints. In this paper, we propose a method to build up the repre...
