A poker-game-based feedback suppression algorithm for satellite reliable multicast

ATELLITE networks will have a crucial role for global s multicast services due to their large coverage area, abundant bandwidth particularly at higher frequency, and rapid network setup. As in terrestrial reliable multicasting cases, however, feedback implosion 141, [6], [9] is identified as a major problem in satellite multicast. The feedback implosion occurs when a large number of receivers sends their feedback to the satellite. The amount of potential feedback increases linearly with the number of receivers and may lead to a high traffic concentration at t.he satellite. In this paper, we propose a poker-game-based feedback suppression (PFS) algorithm to reduce the number of feedback messages. The remainder of this paper is organized as follows: the PFS algorithm is described in Smection 11. Section III provides parameter choice and estimation techniques for the PFS scheme. Performance results are given in Section IV. Finally, conclusion is drawn in Section V.
