Aiming at the existing IP geolocation approaches does not consider the errors of landmarks and delay; a new geolocation approach-utilized landmark calibration is proposed in this paper. At first, we find out these landmarks shared the nearest common router with a target IP by path detection; second, a deviation is assigned to each related landmark according to the corresponding organization and network...
Density and accuracy of network entity landmarks are an important foundation of IP geolocation. For the existing problems of the limited quantity and low reliability of landmarks mined by current landmark mining methods, an algorithm of city-level landmark mining based on Internet forum is proposed in this paper. Firstly, the basic principle of Web-Based landmark mining methods and their existing...
Aiming at the existing IP geolocation approaches does not consider the errors of landmarks, a new geolocation approach utilized landmark calibration is proposed in this paper. At first, by assigning a deviation, the location of the landmark with low reliability is regarded as a possible area, then geolocating the target IP can be converted into a constrained optimization problem, finding the location...
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....
