超マルチホップ、異無線システム間結合を実現する小型IoTゲートウェイ
Super-Multihop and Heterogeneous-Wireless Supported Smart IoT Gateway

概要

The innovation that shapes up the coming future revolves mostly around Internet of Things (IoT), which links things together in large scales. As the need to promote an interoperable and compliant wireless communication standard based solution for the IoT becomes more critical than ever, Wi-SUN FAN (Wireless Smart Utility Network Field Area Network) has been standardized. Wi-SUN FAN delivers interoperable solutions to a wide range of IoT applications, including utility industry, smart cities, agriculture, security and health care management. Wi-SUN FAN successfully operates in Low power and Lossy Networks (LLNs), nonetheless, the further stable routing optimization and the expansion to support mobile environment are required. In this presentation, the demonstration of Wi-SUN FAN platforms and the accomplishment regarding the dynamic routing protocol supporting mobile nodes are presented. In addition, a smart and small IoT gateway that can operate heterogeneous-wireless systems of Wi-SUN FAN, Bluetooth and Wi-Fi by implementing the developed routing algorithm is newly developed. After data accumulation and transmission via Bluetooth, the Wi-SUN FAN-equipped smart IoT gateways serve as relay stations to achieve the super-multihop data transmission with high performance before uploading to cloud platform by Wi-Fi. The multihop operation of IoT devices is demonstrated. The demonstrations and the proposed algorithm allow this combination to fortify the versatility of wireless communication and establish the seamless interoperation.

産業界への展開例・適用分野

Wi-SUN FAN has been implemented in many smart sensors and smart devices to establish smart cities in many countries, including Japan. With demand of several 100 million Wi-SUN FAN devices, the cost reduction of IC chips and the reliable supply for Wi-SUN FAN devices may be practical in the near future. In addition, with the accomplishment of mobile support in this research, Wi-SUN FAN is expected to be prevailingly carried by people moving with low speed to accumulate the real-time data and link to cloud platform. With Wi-SUN FAN, the smart life, for example, the guaranteed life security with high reliability, the convenience health checkup, becomes practical.
