Study and performance of localization methods in IP based networks: Vivaldi algorithm

This paper deals with station localization in distributed applications in the Internet. Several localization techniques are described with their advantages and disadvantages. This paper is focused on the sophisticated Vivaldi algorithm and its variations. A special simulation tool was developed in order to simulate the influence of configuration parameters and setting to algorithm performance. Several tests were performed to examine how both convergence and accuracy of localization process are affected by different settings of algorithm constants and by the number of reference points.
