Experiments and analysis of quality andEnergy-aware data aggregation approaches inWSNs
A wireless sensor network consists of autonomous devices
able to collect various data from the area that surrounds
them. However, the resources associated with sensors are
limited and, thus, in order to guarantee a longer life of all
the network components, it is necessary to adopt energysavings
methods. This paper, considering that the transmission
phase is the main cause of energy dissipation, presents
an approach aimed to save energy by capturing and aggregating
signals instead of sending them in raw form. Anyway,
aggregation should not imply the loss of useful data. For this
reason, information about possible outliers is preserved and
the aggregated values have to satisfy data quality (i.e., accuracy,
precision, and timeliness) requirements. In order to
show the correctness and validity of the proposed method,
it has been tested on a real case study and its performance
has been compared with two other consolidated approaches
