US 2019/0319705 A1 · AD HOC LIGHT-BASED MESH NETWORK

Abstract

Techniques are described for providing an ad hoc mesh network of nodes that employ a light-based transmission protocol, such as a version of light fidelity (LiFi). The mesh network includes multiple nodes that each includes transceiver(s) for sending and receiving light-based communications. A node in the mesh network can receive a message signal sent by another node, by detecting the light modulations emitted by the sending node to transmit the message signal. The receiving node can forward the message signal to other node(s) that are proximal to the receiving node (e.g., that are in line-of-sight with the receiving node), by emitting the appropriate light modulations to send the message signal. In this way, a message signal can be conveyed from one node to another, from one endpoint of the mesh network to another endpoint of the mesh network.

Dependent claims

A system for communicating messages, the system comprising:

a plurality of nodes each including at least one light fidelity (LiFi) transceiver, each respective node configured to perform operations including:
receiving, at the respective node, one or more LiFi discovery signals, each LiFi discovery signal sent from a respective proximal node and conveying a node identifier (ID) of the respective proximal node;
in response to receiving the one or more LiFi discovery signals, storing proximal node data that includes the respective node ID of each of the one or more proximal nodes to indicate that the one or more proximal nodes are available for LiFi communication with the respective node;
and
receiving a LiFi message signal at the respective node and, in response, determining at least one of the one or more proximal nodes indicated in the proximal node data to re-transmit the LiFi message signal to, and re-transmitting the LiFi message signal to forward the LiFi message signal to the at least one of the one or more proximal nodes indicated in the proximal node data.
