A Robust Network Connection Across Internet of Things Devices Inside the Room with Visible Light Communication

In order to better monitor and engage with the communal assets of smart cities, the amount of Internet of Things (IoT) devices that have been installed has been continuously rising. This might result in a reduction in network efficiency as a consequence of the increasing volume of network traffic and connections brought about by different Internet of Things devices. In order to address these challenges, one approach that shows promise is to take advantage of the close physical proximity of communicating devices and to facilitate communication between individual devices in order to achieve low latency, efficient use of bandwidth, and reliable service. Taking use of new technologies like visible light and ultrasound, our study aims to improve the performance of indoor Internet of Things (IoT) connectivity in settings such as smart homes and small office and home offices (SOHO). This method expands the capacity of the network, ensures that network connections among IoT devices are stable, and offers effective ways to allow distance-bounding services. We have constructed communication modules for visible light and ultrasonic using off-the-shelf components, and we are now evaluating their network performance as well as their energy usage.
