A NS-2 Simulation model of DVB-S2/RCS Satellite network
نویسندگان
چکیده
Satellite networks are enhanced permanently: new coding techniques, changes in the allocation algorithm or new technologies. These features are first implemented on a test bed in order to prove their efficiency, but an emulation platform is expensive and its implementation is time consuming. A simulation model can solve these issues, by giving a first try out and another way to obtain measurements. Of course, this model has to be as close as possible to the real system by its behavior but also by the layout of its components. The previous reasons lead us to realize a model of a DVB-S2/RCS satellite network on NS-2.

متن کاملA Cross-Layer PEP for DVB-RCS Networks
The aim of this paper is to consider the problems of TCP performance in broadband GEO satellite networks and to propose a crosslayer approach for a transport-layer PEP that makes spoofing actions on ACKs to modify them in case the satellite network is congested. This approach is investigated here from the signaling standpoint with a special attention to the BSM reference model and considering a...
