中文摘要：
针对卫星网络传输时延长、通信时间短和突发业务量大的特点,首先设计了高优先级、高实时性业务主动重传策略,然后在此基础上提出了一种面向卫星网络的主动重传扩频时隙ALOHA多址接入控制方法。该方法融合了扩频通信、S-ALOHA随机访问控制协议和主动重传策略的优点,能满足特殊环境中提供＂区分服务＂的实际要求。最后的仿真结果不仅证实了该方法的吞吐性能比时隙ALOHA系统有了很大的提高,而且能以较小的吞吐量损失为代价增加高优先级业务的成功发送率。
英文摘要：
For satellite network with high propagation delay,short communication time and sudden large amount of business,an active repeat transmission strategy applicable to high-priority and real-time business was designed,and based on it,the multiple access control method of active repeat spread spectrum slottedALOHA（AR-SS-S-ALOHA） for satellite communication network was presented.The proposed method combines the advantages of spread spectrum communication,S-ALOHA random access control protocol and active repeat transmission strategy,and can provide ＂differentiated services＂in special circumstances.Finally,computer simulations demonstrate that AR-SS-S-ALOHA has not only better throughput performance than that of S-ALOHA,but also increases effective sending rate of high-priority business with a slight loss of throughput.
