Improvement of Location Accuracy by Adding Nodes to Ad-Hoc Networks
Article Ecrit par: Picard, Joseph S. ; Weiss, Anthony J. ;
Résumé: We discuss the effect of adding nodes on the location accuracy of Ad-Hoc networks. All results are obtained by analyzing the Cramér-Rao Lower bound. We show that for planar network the additional node must have at least 3 connections in order to have any effect on the existing nodes accuracy. Further, we identify the nodes whose accuracy will be improved. Finally, we show that the accuracy cannot be improved without limit by adding more and more nodes to an existing network.
