太赫兹频段的新兴通信技术,包括自由空间光通信(FSO),有可能通过补充传统的射频(RF)无线网络来帮助解决频谱稀缺问题。视距(LOS)链路发现是这些高方向性频段的主要限制因素之一,当邻居节点之间没有彼此位置的先验知识时,建立LOS的问题变得更加具有挑战性。在这项工作中,我们提出了一种使用螺旋扫描的异步LOS发现算法,而不需要通过射频信道进行任何同步。我们还通过一个配备带内全双工(IBFD)FSO收发信机的无人机原型进行了试验台实验,验证了算法的有效性。
Emerging communication techniques in terahertz bands, including free-space optical (FSO), have the potential to aid in solving the spectrum scarcity problem by complementing the traditional radio frequency (RF) wireless networks. Line-of-Sight (LOS) link discovery is one of the major limiting factors for these highly directional bands, and this problem of establishing LOS between neighbor nodes becomes more challenging when they have no a-priory knowledge of the location of each other. In this work, we present an asynchronous LOS discovery algorithm using spiral scanning without any synchronization via an RF channel. We also demonstrate the effectiveness of the algorithm through test-bed experiments using a prototype of UAVs equipped with in-band full-duplex (IBFD) FSO transceivers.
