Although many localization protocols have been proposed for wireless sensor networks in a three dimensional topology, the demand to further improve the accuracy of node positioning method make it necessary to design and develop new localization algorithms. In this paper, a three-dimensional localization algorithm of wireless sensor networks base on particle swarm optimization (TLP) is presented. By...
Clustering is a standard approach for achieving efficient and scalable performance in wireless sensor networks (WSNs). Especially, some sensor network applications need some nodes to affiliate to more than one cluster. This paper focused on studying the impacts of a duty-cycle based connected k-neighborhood (CKN) sleep scheduling algorithm for a multi-hop overlapping clustering algorithm in WSNs....
