摘要

现有的水声网络介质访问控制(MAC)协议大多忽略了影响往返时间(RTT)估计精度的时延方差。我们使用贝叶斯动态线性模型预测rtt。利用预测的rtt动态调整MAC中时隙的长度。实验结果表明，预测值能快速适应声道中的时延变化。

A new MAC based on RTT prediction for underwater acoustic networks

Most existing medium access control (MAC) protocols in underwater acoustic networks (UANs) ignore the delay variance that affects the estimation accuracy of round trip time (RTT). We predict the RTTs using Bayesian dynamic linear model. Using the predicted RTTs, we dynamically adjust the length of time slots in MAC. Experimental results show that the predicted values can adapt quickly to the delay variance in the acoustic channel.
