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 source loads. The use of cooperation can allow improving system performance depending on the number of cooperators considered and the different channel conditions which they are subject to, and increasing the number of scenarios characterized by different propagation conditions wherein the system can transmit data packets compared to the case of absence of cooperation.
