| 摘 要： | 基于窄带半双工信道的军用无线网络限制了ACK反馈信息的及时性和有效性,使得单程时延和交付概率等端到端传输指标成为发现网络拥塞的有效途径。利用M/G/1模型的排队方法分析和揭示了无线自组织网络中节点拥塞程度、链路层参数以及业务层面的性能参数之间的量化关系,从而为窄带无线自组织网络的拥塞控制协议设计提供了理论依据。

| Abstract: | Military wireless networks which are based on narrowband and half duplex channel make it is hard to utilize ACK as a indication for congestion.So the one way end to end delay and packet delivery probability become the important parameters to predict the avoidance.This paper analysed and revealed the numerical relationship among the congestion level,link layer parameter and app layer performance through M/G/1 queueing model,thereby,provided theoretical principle for design of congestion control algorithm. |

| Keywords: | Ad hoc Congestion avoidance Delivery probability |
