IP-Geolocation Mapping for Involving Moderately-Connected Internet Regions
Source: University of Minnesota
Current IP-geolocation mapping schemes primarily take delay-measurement approach, and most of them are based on the assumption of a strong correlation between networking delay and geographical distance between the targeted client and the landmarks. In this paper, however, the authors investigate a large region of the Internet and find the delay distance correlation is weak. The authors call this kind of Internet regions moderately-connected Internet regions. But the authors discover a more probable rule - with high probability the shortest delay comes from the closest distance. Based on this closest-shortest rule, the authors propose a simple and novel IP-geolocation mapping scheme for involving moderately connected Internet regions, called GeoGet.
