Abstract
In this paper the reference system is given by wireless usersaboard of fast moving vehicles, such as trains, connected to theInternet by means of satellite links. Performance of several TCPflavors are investigated in this scenario and they are obtained bysimulation in presence of hand-overs which happen when a trainenters a tunnel and the satellite comes to be unreachable. Thesehand-overs imply time intervals during which data flows are slowdown or blocked. Results show that depending on their duration,users performance can be remarkably affected.
