[MGI30-06] Development of LPWA and visual IoT techniques (5)
Keywords:LPWA, LoRa,, Visual IoT
Visual Internet of Things (IoT) is a class of IoT that collects rich visual data. In general, the visual IoT device is equipped with a video transmission equipment such as a camera. The involved technologies are advanced video transmission techniques and information extraction from images by image recognition techniques. However, since the video data size is larger than the sensor data size, one of the issues of visual IoT is high-performance video transmission in networks in which the bandwidths are limited. In this paper, we design and develop a real-time monitoring system using visual IoT device. Our system is based on a novel protocol, named high-performance video transmission (HpVT), for field monitoring via 4G LTE mobile networks.
In this presentation, we propose a new energy-harvesting LoRa communication protocol for LoRa communication systems in mountainous areas where there is no electric power supply. Specifically, we propose a communication method that reliably transmits sensor data installed in mobile communication dead zones over a serial network rather than a mesh network. Furthermore, we conduct transmission experiments using this protocol in the field for a certain period to verify its practicality.
