Abstract:
Abstract—In this paper, we investigate the use of systematic random network coding (SNC) for multicast and multi-unicast over satellite. In particular, the satellite coverage is over a large geographical area that consists of several users. These users may face different channel conditions and undergo different packet loss rates. In this work, we identify two regions of transmission. The multicast region where all users subscribed to the multicast channel can recover all the data packets and the multi-unicast region where only users with good channel conditions can recover all the data packets but those with bad channel accept transmission losses. For the two regions, we derive theoretically and by simulation the benefits of SNC against state-of-the-art end-to-end coding. Our results show that SNC can achieve up to 26.90% and 24.26% higher maximum achievable rates for multicast and multi-unicast respectively. Further, we show practical architectural and encapsulation feasibility.
