A Prediction-Based Scheduling Mechanism for Interconnection between WiMax and Satellite Networks Interactive Network

In this paper, we describe and evaluate a scheduling mechanism that can be used in joint satellite/WiMax environments. The proposed mechanism consists of three parts. The first part requests satellite bandwidth based on an estimation of the needs of the WiMax network at the time the bandwidth is granted. The second part allocates bandwidth on the satellite channel, while the third distributes it to the WiMax users. Simulation results show considerably improved performance compared to a simpler mechanism, especially in terms of throughput and delay.
