Localization that is to be aware of position of the node in the network is an essential issue in Wireless Sensor Network (WSN). Localization algorithm in WSN can be divided into range based and range-free algorithm. In this paper, the authors present the analysis of DV-Hop (Distributed Voronoi) using Voronoi diagrams in order to scale a DV-Hop localization algorithm while maintaining or even reducing its localization error. With this they tried to analyze the efficiency of the DV-Hop localization algorithm by changing various parameters. They show how the proposed algorithm can scale in different aspects such as communication and processing costs when increasing the number of nodes and beacons.
