A flow control for reliable unidirectional satellite broadcast systems

The warning system is required to preserve viability and ability from diversified air threats. The unidirectional satellite multicast system, the new system has attracted attention as an alternative. The system is similar to a unidirectional satellite link. To improve link reliability, the unidirectional satellite link uses a flow control. But it is unsuitable for the unidirectional satellite multicast system because it is not able to be considered of the small number of receivers which are in low condition. In this paper, we propose a flow control for a unidirectional satellite multicast system. In our design, we take care of the characteristics of the multicast system. Our experimental results show that the unidirectional multicast system provides flow control for reliability. Also it provides efficiency when there is occurrence the no-reception problem.
