ABSTRACT
This paper presents a performance analysis of the TCP protocol considering the DiffServ architecture to provide Quality of Service guarantees working over a Digital Video Broadcasting-Second Generation (DVB-S2) satellite system. The analysis is carried out using the NS-2 simulator tool where three TCP variants are considered: Sack TCP, Hybla TCP and Cubic TCP. The objective is to evaluate the TCP performance taking in to account goodput, friendliness and fairness parameters and the most typical problems presented in a DVB-S2 satellite link such as delay, losses and bandwidth variations.

A Throughput Analysis of TCP Variants in Mobile Wireless Networks
NGMAST '09: Proceedings of the 2009 Third International Conference on Next Generation Mobile Applications, Services and TechnologiesUnlike wired networks, random packet loss due to bit errors is not negligible in wireless networks. These networks have mobility as another challenge. This causes significant performance degradation of TCP. Different Variants of TCP exist; some have no ...
