This work presents an innovative, adaptive and optimal approach for Slotted-ALOHA protocols in Satellite Networks. Most ALOHA random access protocols are based on the assumptions that: i) all the involved stations receive packets with the same rate and ii) the transmission probabilities, computed analytically, are the same for each station. These assumptions are too optimistic, since, in real scenarios,...
This paper reports a study concerning the assessment of cooperation effects at MAC layer in DVB-RCS systems. In particular, a modified resource allocation mechanism has been considered in order to implement a Selective Forwarding cooperation scheme within a group of sources working in a land-vehicular scenario. The achieved results are presented in terms of aggregated average throughput for different...
Designing new satellite access protocols or validating innovative satellite network concepts, evaluating their performances and demonstrating them require powerful test tools to check their compliance with satellite system requirements. Obviously, such tools have to be as representative as possible of typical satellite telecom systems, but also adaptable to specific research and engineering needs...
