A Comparison of Multicast Adaptive Techniques in Reliable Delivery over GEO Satellite Networks

In this paper, we compare two multicast adaptive techniques for reliable data delivery in GEO satellite networks. Specifically, a channel-aware scheduling algorithm is compared with a multicast link adaptation technique, in the face of fluctuating channel conditions in downlink. The aim of the techniques is to maximise system throughput whilst increasing resource utilization. The scheduling technique is implemented within one forward bearer subtype, whereas the link adaptation mechanism considers transmission rates from a list of possible forward bearer subtypes. Simulation results are analysed and it is found that multicast link adaptation technique outperforms channel-aware scheduling algorithm, in terms of reduced session delay and retransmitted number of segments.
