Advance Scheme for Localization Using Curvilinear Component Analysis
The performance of applications of wireless sensor network depend upon the precise location of the nodes. The localization protocol patches together the relative coordinate, local maps into a global coordinate map. These protocols require some nodes that know their absolute coordinates, called anchor nodes. While many factors influence the node position errors, in this class of protocols, using Procrustes Analysis, the placement of the anchor nodes can significantly impact the error. Through simulation, using the Curvilinear Component Analysis (CCA-MAP) protocol, the authors show the impact of anchor node placement and propose a set of guidelines to ensure the best possible outcome, while using the smallest number of anchor nodes possible.
