Abstract
DVB-S2 is a second-generation standard for satellite transmissions, developed to improve the performance of DVBS. Recently, research efforts have been devoted to extend this standard for mobile usage. In this paper we consider a scenario composed of a Ku-band GEO bent-pipe satellite, a gateway and some mobile users. The interest is here in investigating the performance of a scheduling scheme to manage DVB-S2 resources on the forward channel for the delivery of video CBR and FTP traffic flows to mobile users. A novel scheduler scheme, called UBMT, has been proposed that aims to manage CBR packet transmission deadlines while maximizing the aggregated goodput. Simulation runs have permitted to validate the optimal performance achieved by UBMT in comparison with other schemes. The impact of different TCP versions has been investigated as well showing the good results obtained with the SACK option.
