论文摘要
在这项工作中,我们考虑了无线网络的延迟,这是由于需要可靠和低延迟的无线通信来进行用于车辆到车辆通信和工业自动化等应用的促进。这些应用程序运行的环境通常是高度动态的,因此,使用的无线网络技术需要能够适应不断变化的条件,从而使网格网络变得非常合适。因此,在这项工作中,我们考虑线程和蓝牙网格,这是两种突出的网络网络技术。我们使用这些技术测量单向点对点延迟,并显示有效载荷大小的延迟的累积概率分布。我们在露天环境中在静态条件下进行测量。我们的结果表明,线程比蓝牙网格的延迟较低,尤其是对于较大的有效载荷。此外,我们表明线程符合一些以5G为例的延迟目标。但是,由于线程网络适应网络更改的速度很慢,因此线程可能仍然不适用于需要低延迟的应用。另一方面,蓝牙网格不符合任何延迟目标,尽管有效载荷很小(小于11个字节)时,蓝牙网眼已接近。总体而言,需要进一步优化,然后才能在动态环境中使用这些技术进行可靠和低延迟的通信。
In this work, we consider latency in wireless networks, motivated by the need for reliable and low-latency wireless communication for applications such as vehicle-to-vehicle communication and industrial automation. The environment that these applications operate in is often highly dynamic, and, as a result, the wireless network technology used needs to be able to adapt to changing conditions, which makes mesh networking a good fit. Hence, in this work, we consider Thread and Bluetooth Mesh, two prominent mesh networking technologies. We measure one-way point-to-point latency using these technologies and show the cumulative probability distribution of the latency for varying payload size. We carry out the measurements under static conditions in an open-air environment. Our results show that Thread achieves lower latency than Bluetooth Mesh, especially for larger payloads. Furthermore, we show that Thread meets some of the latency targets set out for 5G. However, since Thread networks are slow to adapt to network changes, Thread may still not be suitable for application requiring low latency. Bluetooth mesh, on the other hand, does not meet any of the latency targets, although it is close when the payload is small (less than 11 bytes). Overall, there needs to be further optimization before these technologies can be used for reliable and low-latency communication in dynamic environments.
