A cluster is defined as a subset of … WebThe remainder of this chapter is organized as follows. In Section 22.2, we investigate previous work on the clustering scheme and the hierarchical structure scheme in wireless sensor networks and RFID networks. In Section 22.3, we propose w-LLC, a weighted dynamic localized scheme designed for hierarchical clustering protocols.

WebHierarchical clustering is an unsupervised learning method for clustering data points. The algorithm builds clusters by measuring the dissimilarities between data. Unsupervised learning means that a model does not have to be trained, and we do not need a "target" variable. This method can be used on any data to visualize and interpret the ...
