Outlier-Aware Data Aggregation in Sensor Networks

Wireless sensor networks often consists of a large number of low-cost sensor nodes that have strictly limited sensing, computation, and communication capabilities. Due to resource restricted sensor nodes, it is important to minimize the amount of data ...

A sink node must be aware of the identifications (node IDs) of those all sensor nodes which contribute in aggregated value of sensors data in order to derive exact result of them in privacy preserving data aggregation scheme for wireless sensor networks ...

In the field of wireless sensor networks, those measurements that significantly deviate from the normal pattern of sensed data are considered as outliers. The potential sources of outliers include noise and errors, events, and malicious attacks on the ...
