IP Geolocation is used to determine the geographical location of Internet users based on their IP addresses. When it comes to security, most of the traditional geolocation analysis is performed at country level. Since countries usually have many cities/towns of different sizes, it is expected that they behave differently when performing malicious activities. Therefore, in this paper we refine g...

Title of thesis: METROPOLITAN AREA NETWORK IP GEOLOCATION THROUGH WAVELET TECHNIQUES Choon Yik Lee, Master of Science, 2010 Thesis directed by: Professor Richard La Department of Electrical and Computer Engineering IP geolocation is the process of finding the geographic locations of Internet hosts. We will focus on Internet hosts in metropolitan area network(MAN). The Internet hosts will be und...

Knowing the geographical location of an Internet host is of importance to many of today’s Internet services. In this paper we focus on geolocating Internet hosts based purely on latency measurements. Existing latency measurement-based geolocation techniques use the observed latencies from multiple landmarks to the target host to determine maximum bound or both the maximum and minimum bounds of ...

Current IP-geolocation mapping schemes [10], [12], [13], [14] 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, we investigate a large region of the Internet and find the delaydistance correlation is weak. We call...

Estimating the location where an image was taken based solely on the contents of the image is a challenging task, even for humans, as properly labeling an image in such a fashion relies heavily on contextual information, and is not as simple as identifying a single object in the image. Thus any methods which attempt to do so must somehow account for these complexities, and no single model to da...

The robust and scalable growth of the Internet has allowed value added services that provide enhanced user experience. Offering information based on geographic location to Internet users is one of the newest and notable advancements. Finding the geographical location of the user on the Internet, commonly referred to as geolocation, is one of the challenging problems currently addressed by the r...

Geolocation data were recovered from archival tags applied to bigeye tuna near Hawaii. A state-space Kalman filter statistical model was used to estimate geolocation errors, movement parameters, and most probable tracks from the recovered data. Standard deviation estimates ranged from 0.5 to 4.4 latitude and from 0.2 to 1.6 longitude. Bias estimates ranged from )1.9 to 4.1 latitude and from )0....
