基于GMR-1卫星通信系统的无线分组调度算法研究

摘要

As a complement to terrestrial communication system, the satellite communication system can cover almost anywhere on the earth which makes it worthwhile studying. Referring to M-LWDF algortithms, this paper takes the high delay and low power of GMR-1 satellite system into consideration and propose an radio packet scheduling algorithm. Aiming at guaranteeing fairness between users , the algorithm can provide different kinds of radio resource that is required for RT(Real Time) or NRT (None Real Time) business.At last, we contrast the different capacity of different algorithms.%卫星通信系统作为陆地通信系统的补充,几乎可以覆盖到地球的所有地点,因此具有很大的研究价值.在参考了前人提出的M-LWDF算法后,文章考虑到GMR-1卫星通信系统的高时延、低功率等因素的影响,提出了针对该系统的无线分组调度算法,本算法以保证用户公平性为前提,实现了为实时业务、非实时业务分别提供满足要求的无线资源的目的.最后,在仿真中对比了不同算法的性能.
