摘要
针对传统的数据传输速率优化模型存在传输效率较低、延时较长等问题,构建一种监控网络测点数据传输效率优化模型。利用全变差正则化方法对监控网络测点信号进行去噪,考虑网络测点数据序列已经到达节点等待传输,引用内罚函数优化测点数据传输过程,并构建监控网络测点数据传输效率优化模型,使得固定时间内测点数据传输量为最大,实现监控网络测点数据传输效率优化。实验结果表明,所提模型数据传输效率较高,且大幅度降低了数据传输延时。
Due to low transmission efficiency and high time delay in traditional optimization model of data transmission rate,this paper put forward a model to optimize data transmission efficiency for measurement point in the monitoring network.The total variation regularization method was used to reduce noise of measurement point signal in monitoring network.Because the data sequence of network measurement points had arrived at the node and waited for transmission,the internal penalty function was introduced to optimize the data transmission process of measurement point data.Meanwhile,the optimization model of data transmission efficiency of measurement point in monitoring network was constructed to maximize the amount of data transmission in a fixed time.Finally,the optimization of data transmission efficiency for measurement point in monitoring network was achieved.Simulation results show that the data transmission efficiency of above model is high and the time delay of data transmission is greatly reduced.
