Design and Implementation of a Multi-Node Optical Wireless Communication Testbed for Centralized Configuration and Adaptation of System Parameters using GNU Radio’s XML-RPC and ZMQ Modules
Abstract
Over the past two decades, Software Defined Radio (SDR) techniques have allowed the RF community to bring many wireless communications topics and educational tools from theory and simulation to experimental test systems. In our work, we have brought these capabilities to the field of optical wireless communications (OWC). In this article, we discuss key capabilities for extending our prior work to multi-cell and multi-user OWC systems with centralized configuration and control. These capabilities are enabled by GNU Radio and introduced within the gr-owc out-oftree library. We highlight how these capabilities are being applied for automated data collection and how the work enables future opportunities in systems-level research for OWC networks.
