| 摘 要： | 为了克服经典PRMA-HS协议中的双稳态问题和分组发送允许概率的静态性缺点,提出了一种基于状态响应的改进型分组预约多址接入协议。通过接收卫星基站的状态反馈信息,根据系统状态实时调整分组发送允许概率,使系统始终处在最佳状态。利用计算机对理想信道和随机误差信道条件下的协议性能进行了仿真,结果表明,采用状态响应机制能够克服经典PRMA-HS协议的双稳态问题,提高了协议的稳定性,增加了系统容量,降低了分组丢弃率。

| Abstract: | A modified packet reservation multiple access protocol based on state response is proposed in allusion to the bistable behavior and static state of packet transmitting permission probability in the classical PRMA-HS protocol.The modified protocol could adjust the packet transmitting permission probability dynamically according to the state of system by the response message of satellite base station in order to keep the optimal system sate.Performance of the modified protocol under ideal and random packet er... |
