Abstract

This correspondence focuses on critical information exchanges between two remote multicast groups via a satellite system for emergency and alerting scenarios. In particular, here, we deal with the use of an efficient network coding (NC) communication scheme to reduce data flow delivery delay, save energy, and guarantee reliable reception within a target outage decoding probability at all on-earth receiving end. A suitable optimization procedure is also proposed to achieve the best NC performance. The typical case of Rayleigh channel propagation conditions is considered in our analysis to validate the obtained results in realistic environments. Finally, performance comparisons with NC schemes previously proposed for multicast reliable satellite communications and a negative-acknowledged-based alternative are provided to clearly highlight the better behavior of the proposed NC scheme.
