چکیده (انگلیسی):

Satellite networking is different from wired or wireless networks. TCP/IP performance and behavior with
respect to normal wireless network and wired networks are different from one another. As the architecture
of TCP/IP protocol was not designed to perform well over high-latency or noisy channels and so its
performance over satellite networks are totally different. The properties of satellite constellations such as
the deployment height, motion, direction, link capacity-all differ from one satellite constellations to another.
So, certainly the behavior of TCP/IP will considerably differ from one satellite constellations than another and
the impact of TCP on the performance of satellite communications was discussed. In this study, we are
evaluating the performance of different TCP Congestion algorithms namely Vegas, Reno and Bic on Teledesic
satellite constellations. The above mentioned TCP congestion control algorithms are taken for evaluation on
the simulated satellite network Teledesic and the performance of the three algorithms under the satellites
constellation is measured using suitable metrics to improve the transmission of data packets over satellite links.
