【摘要】 对网络信道通信传输效率进行控制,能够有效提高动态数据通信效果,满足如今数据通信需求。对网络信道通信传输效率的控制,需要测量传送数据的效率值,判断数据通信信道是否有堆积现象,获取恢复拥塞窗口函数,完成通信传输效率的控制。传统方法利用改进的ARUDP协议,在接收端单向队列的时延来检测网络状态,但忽略了对网络信道通信窗口函数,导致效率控制效果不理想。提出基于Ad Hoc的信道通信传输效率控制方法,依据分解得到的小波系数选取一个阈值,对通信信道原始信号进行重建,通过慢启动法,实现网络拥塞窗口的增大,提升网络数据通信效率;测量每次由传送端传送数据的效率值,并判断数据通信信道是否有堆积现象;获取网络拥塞避免函数和恢复拥塞窗口函数。实验表明,该方法体现出了高效信道抗干扰的性能,数据通信效率控制效果相比当前方法更显优越。更多还原

【Abstract】 In order to overcome the defect of traditional control method for communication transmission efficiency of network channel,such as poor control effect,a new control method is proposed based on Ad Hoc. Firstly,according to wavelet coefficient after decomposition,a threshold was selected and original signal of channel communication was rebuilt. Then,enlargement of network congestion window was achieved via slow start method to improve communication efficiency. Each efficiency value of data transferred by source agency was measured and packing phenomenon of data communication channel was judged. Finally,congestion avoidance function of network and window function of congestion recovery were acquired. Simulation shows that the method expresses high anti-interference property.Compared with current methods,the proposed method has better control effect of data communication efficiency.更多还原
