ABSTRACT: In this paper, a Data De-noising Clustering (DDC) algorithm for data aggregation is proposed.
By considering the noisy data of sensor nodes, the algorithm introduces a Weighted Moving Average (WMA)
and improves it, then apply it to data de-nosing. Moreover, we utilize the spatial correlation between nodes to
divide nodes into different clusters and present a correlation degree for cluster head selection so that the data
of the cluster ...
