چکیده
The design of cross-layer scheme, which plays a key role in satellite resource management, is crucial for the data transmission in the CCSDS AOS. In this paper, a novel dynamic cross-layer scheme, which satisfies QoS service, is proposed. This scheme can utilize both the applications’ QoS attributes and physical layer channel state information to change virtual channel bandwidth and transmission power in order to optimize resource and improve system performance. The performance of the proposed scheme has been evaluated via simulation. The proposed scheme achieves significant performance in the field of average transmission delay, loss packet rate and average throughput.
