| Abstract |
In industrial fields such as smart grid and environmental facility management, a low-power wireless communication network that can cover a wide range was developed to collect information generated from devices distributed in a wide area. However, in a clean room of a semiconductor or display factory, numerous IoT devices are distributed in an ultra-high density to increase product yield and to control precise air quality. In such an environment, it is necessary to secure the reliability of the wireless data transmission success rate or delay time, and to maintain stable operation for a long time. To this end, in this paper, we propose a Dual MAC-based high-density network communication algorithm that designs the network in two-layered high-reliability data transmission in a wireless environment of ultra-high-density devices. An NFC-based device ID setting and monitoring system was implemented. As a result of testing in a dense environment with 500 devices, it achieved a data packet delivery success rate of more than 99% and a transmission delay time of less than 40msec, required in an industrial environment. |
