Estimation of Internet Node Location by Latency Measurements - The Underestimation Problem

Popis výsledku v původním jazyce

In this paper we deal with discovering a geographic location of a node in the Internet. Knowledge of location is a fundamental element for many location based applications and web services. We focus on location finding without any assistance of the nodebeing located - client-independent estimation. We estimate a location using communication latency measurements between nodes in the Internet. The latency measured is converted into a geographic distance which is used to derive a location by the multilateration (triangulation) principle. We analyse the latency-to-distance conversion with a consideration of location underestimation which is a product of multilateration failure. We demonstrate that location underestimations do not appear in experimental conditions. However with a real-world scenario, a number of devices cannot be located due to underestimations. Finally, we propose a modification to reduce the number of underestimations in real-world scenarios.
