Multimedia Data Sharing and Autonomous Configuration with the Short-Range Information Sharing System NAMI

SHONAN, an advanced system harmonizing human capabilities and information technology (IT), was introduced in light of the COVID-19 pandemic, which prompted the shift of office workers and school students to online platforms. In addition, a specific application of SHONAN, referred to as the narrow area communication system (NAMI), was previously implemented, exclusively sharing text-based information. Further, NAMI uses Bluetooth low energy (BLE) to exchange messages; however, it is difficult to exchange large data. In this paper, we have confirmed that it is possible to exchange large data using Wi-Fi under a preliminary experiment.At first, an experimental system was designed on paper in advance. This is insufficient for actual dynamic systems. So, after the preliminary experiment, we considered a method that can allow NAMI functions to continue to be used even when devices and edges move and the network configuration changes dynamically. Further, we implemented and confirmed the functions in the prototype.
