在本文中,我们认为,实现对称误差是提高时钟同步的理解的关键。我们提出了一个时钟同步算法与漂移补偿,实现这种对称误差范例。该算法的性能进行了评估,在室内测试平台上使用TinyNode硬件平台的测量。我们表明,剩余的错误是对称的,在时钟粒度的范围内。
In this paper we argue that achieving symmetric errors is the key to an improved understanding of clock synchronization. We present a clock synchronization algorithm with drift compensation that implements this symmetric error paradigm. The performance of the algorithm is evaluated by measurements in an indoor testbed using the TinyNode hardware platform. We show that the remaining error is symmetric and in the range of the clock granularity.
