论文摘要
由于对电磁波的强大控制，因此设想，元信息可以在下一代无线系统中发挥关键作用。在过去的十年中，在这方面取得了巨大的进步，从静态转移到可编程的跨国。 HyperSurface（HSF）范式通过在设备中集成控制器网络，以增加智能，连接性和自主权，从而进一步迈出了一步。但是，随着目标电磁功能或边界条件的变化，该网络必须支持的流量知之甚少。在本文中，我们奠定了一种方法论的基础，以表征可编程元信息的工作量，然后采用它来分析光束转向HSF的情况。我们观察到流量是爆发的，并且高度依赖于目标的位置。这些结果将使HSF网络的早期评估以及系统性能和成本的估计。
Metasurfaces are envisaged to play a key role in next-generation wireless systems due to their powerful control over electromagnetic waves. The last decade has witnessed huge advances in this regard, shifting from static to programmable metasurfaces. The HyperSurface (HSF) paradigm takes one step further by integrating a network of controllers within the device with the aim of adding intelligence, connectivity, and autonomy. However, little is known about the traffic that this network will have to support as the target electromagnetic function or boundary conditions change. In this paper, we lay down the foundations of a methodology to characterize the workload of programmable metasurfaces and then employ it to analyze the case of beam steering HSFs. We observe that traffic is bursty and highly dependent on the position of the target. These results will enable the early-stage evaluation of intra-HSF networks, as well as the estimation of the system performance and cost.
