The ability to determine the geographic location of an Internet host
would enable a variety of applications, such as targeted advertising,
content specialization, and E-911. In this project, we develop
and evaluate algorithms to automate the task of finding the geographic
location using just network measurements. Our approach improves on earlier
techniques by leveraging network topology, along with measurements of
network delay, to constrain host position. We convert topology and
delay data into a set of constraints, then solve for router and host
locations simultaneously. This approach improves the consistency of
location estimates, reducing the error substantially for structured
networks in our experiments on Abilene and Sprint.
