Due to the lower performance of congestion control mechanism and high production of bandwidth and delay
a multi-rate multicast congestion control mechanism for geosynchronous earth orbit (GEO) satellite network (MMCCM_GEO) was proposed.First
under the premise of maximizing the require rate of receivers
the multi-rate multicast congestion control problem for GEO satellite network was formulated as a nonlinear optimization problem
and the improved simulated annealing algorithm was employed to obtain globally optimal solution.Then
the issue with acknowledgement (ACK) implosion and loss data recovery was settled by proxy node.Simulation results reveal that the proposed mechanism obtains better throughput and bandwidth utilization
and achieves better scalability
compared with the typical conventional multi-rate multicast congestion control mechanism.
