Reliable Communication in a Multi-Transceiver Mobile Optical Wireless Network

In this paper, we investigate a mobile optical wireless networking system enabling reliable transfer of data among multiple nodes with no prior knowledge of node locations. Each node is equipped with a multi-transceiver optical wireless communication (OWC) module with electronic beam steering capability. The multi-transceiver design facilitates in establishing multiple simultaneous OWC links with different neighbor nodes. The proposed system ensures error-free data transfer through fast line-of-sight (LOS) discovery, robust maintenance of OWC links, and utilizing reliable communication protocols. We also present a preliminary prototype of our multi-transceiver multi-node OWC system. We evaluate the effectiveness of the proposed system by analyzing the results obtained from testbed experiments using the developed prototype. The results demonstrate that the proposed system can effectively enable reliable communication among multiple mobile nodes.
