N2 - Recently, more research attention has been focused on LEO satellite networks connected to ISL (Inter Satellite Link). A global network, covering the whole earth, can be integrated to the Internet if terrestrial and LEO satellite networks are seamlessly connected by TCP/IP protocol. However, being originally designed for wired networks, TCP does not perform well in satellite networks because of handover and rerouting issues, In this paper, we propose a method for avoiding the unnecessary TCP's retransmission by using observed hop counts. Our simulation results show how our mechanism is effectively avoiding unnecessary fast retransmits and preventing TCP performance degradation.
