Entropy-based Consensus for Distributed Data Clustering
The increasingly larger scale of available data and the more restrictive concerns on their privacy are some of the challenging aspects of data mining today. In this paper, Entropy-based Consensus on Cluster Centers (EC3) is introduced for clustering in distributed systems with a consideration for confidentiality of data; i.e. it is the negotiations among local cluster centers that are used in t...
متن کاملClustering Distributed Sensor Data Streams
Nowadays applications produce infinite streams of data distributed across wide sensor networks. In this work we study the problem of continuously maintain a cluster structure over the data points generated by the entire network. Usual techniques operate by forwarding and concentrating the entire data in a central server, processing it as a multivariate stream. In this paper, we propose DGClust,...
متن کاملCollective, Hierarchical Clustering from Distributed, Heterogeneous Data
This paper presents the Collective Hierarchical Clustering (CHC) algorithm for analyzing distributed, heterogeneous data. This algorithm rst generates local cluster models and then combines them to generate the global cluster model of the data. The proposed algorithm runs in O(jSjn 2) time, with a O(jSjn) space requirement and O(n) communication requirement, where n is the number of elements in...
متن کاملWeighted Dynamic Distributed Clustering Protocol for Heterogeneous Wireless Sensor Network
In wireless sensor networks (WSN), conserving energy and increasing lifetime of the network are a critical issue that has been addressed by substantial research works. The clustering technique has been proven particularly energy-efficient in WSN. The nodes form groups (clusters) that include one cluster head and member clusters. Cluster heads (CHs) are able to process, filter, gather the data s...
