A Novel Resource Allocation Scheme Based on Multi-satellite Terminals in MF-TDMA Satellite Systems

摘要

The future satellite communication systems should be able to accommodate the integrated services with a variety of applications and fulfill Quality of Service requirements. Regarding to the limited and costly resources, a novel resource allocation in a multi-frequency time-division multiple access (MF-TDMA) is proposed. In order to optimize packing performance, the users with more time slots are packed first. The algorithm's performance of delay and channel utilization can be validated through the simulation for different types of traffic. We further compare the performances of classical schemes. The theoretical analysis and simulation results show that that new algorithm can efficiently improve channel utilization in satellite resource allocation, especially when the number of satellite terminals is large. The algorithm is simple and easy to implement in satellite communication system.
