Evaluation of TCP congestion control algorithms on different satellite constellations
M. Nirmala, Ramachandra V. Pujeri · 2013
The efficient modeling of communication networks and the impact of TCP/IP behavior in satellite constellations is an important study. The divergent properties of satellite networks are deployment height, motion, direction, link capacity which differ from one satellite constellations to another. So, certainly the behavior of TCP/IP which was designed for wired channels will considerably differ from one satellite constellations than another. In this paper, we are evaluating the performance of different TCP Congestion algorithms on 2 different satellite constellations, Iridium and Teledesic with respect to certain parameters. The three TCP congestion control algorithms, vegas, reno and bic are evaluated on the simulated satellite network and the performance of the three algorithms under different satellites constellation is measured using suitable metrics to improve the transmission of data packets over satellite links.
