Proposed method estimates target IP region accurately based on path features and landmarks, suggesting improved geolocation.
While the delay-distance correlation among nodes is weak, calculating the distance constraints according to delay may fail to geolocate the target into a right region. Aiming at this problem, a new geolocation method is proposed in this paper, and according to extract path features for all possible regions in use of a large number of landmarks, this method can estimate the region for a target IP. The experiment results shown that, the proposed method can give the geolocation region with high accuracy.
