摘　　要：针对传统网络拥塞控制方法没有考虑到控制丢包率,导致控制效果不佳的问题,提出基于云模型的移动Ad-hoc网络拥塞跨层控制方法。分析移动Ad-hoc网络的分层结构,构建网络拓扑结构模型。运用该模型分析丢包产生的原因,并加以优化。在此基础上为了提升网络链路的使用率、降低网络拥塞程度,在缓冲队列中采用云模型检测网络拥塞情况,调节网络数据的发送速率,从而实现对网络拥塞的跨层控制。通过仿真分析可知,上述方法的控制效果较理想,丢包率较低,有效解决了传统方法中存在较大丢包率的问题,能够为相关工作提供可靠的参考,具有较高的使用价值。Traditionally, the congestion control method does not consider the control of packet loss rate, resulting in poor control effect. Therefore, this article puts forward a cross-layer congestion control method for mobile Ad-hoc network based on cloud model. Firstly, we analyzed layered structure of mobile Ad-hoc network and built the network topology model. Secondly, we used this model to analyze the reason of packet loss. On basis of optimization, in order to improve the utilization of network links and reduce the degree of network congestion, we used the cloud model to detect the network congestion in buffer queue and adjust the transmission rate of network data. Thus, we achieved the cross-layer control for network congestion. By analyzing simulation, we can see that the control effect of the proposed method is ideal and the packet loss rate is low. This method effectively solves the problem of large loss rate in traditional methods and provides reliable reference for related work, so the proposed method has high use value.
