The Performance Analysis of Advanced Centroid Localization Algorithm for Wireless Sensor Network

Localization of nodes is a key technology for application of wireless sensor network. By analyzing the model of the range-free Centroid Localization Algorithm (CLA), this paper presents a new localization algorithm, which can be called Advanced Centroid Localization Algorithm (ACLA). ACLA can deal with the localization precision disadvantage of CLA when the anchor-nodes are placed randomly. The calculation of ACLA is sample, ACLA has less communication overhead. The simulation results indicate that the ACLA has an obvious improvement in localization precision than CLA.
