Abstract

The demand of remote control and monitoring for efficiency and applications of LED streetlight is increasing continuously because the demand of LED streetlight was increase last few years. Existing street light remote control system is wired using a power line network. The wireless connection exists, but due to its low data transmission rate, it cannot support specialized applications. It can only support simple control and monitoring. In this paper, we propose a system that uses a IEEE 802.11s wireless mesh network based on WLAN, as a backbone network for remote control and monitoring of the LED street lights along with other specialized applications. Using the wireless mesh network for remote control and monitoring the LED street lights, the same can be used to act like a public Wi-Fi access point. We have designed Wi-Fi integrated LED streetlight controller and implemented our system. We evaluated the performance of our system on a real test bed. Our proposed system is expected to perform the role of a U-city infrastructure by utilizing the wireless mesh network.

LED 가로등의 수요가 증가하면서 LED 가로등의 효율성 제고 및 다양한 부가서비스를 위한 원격 제어 및 모니터링에 대한 수요가 지속적으로 증가하고 있다. 기존의 가로등 원격 제어 시스템은 전력선 통신망을 이용하는 유선 방식이 주를 이루고 있고, 무선 연결 방식이 존재하나 전송 속도의 제약이 있어 단순 제어 및 모니터링 이외의 부가 서비스를 지원하기에는 어려운 점이 있다. 따라서 본 논문에서는 무선랜 기반의 IEEE 802.11s 무선 메쉬 네트워크를 LED 가로등의 원격 제어 및 모니터링의 백본 네트워크로 사용하는 시스템을 제안한다. 무선 메쉬 네트워크를 사용함으로써 LED 가로등의 원격 제어 및 모니터링과 동시에 LED 가로등이 공공 Wi-Fi 액세스 포인트의 역할을 수행하게 한다. 이를 위해 Wi-Fi 통합형 LED 가로등 컨트롤러를 설계하고 시스템을 구현하고 Test Bed를 구성하여 성능을 평가 하였다. 본 논문에서 제안하는 시스템은 무선 메쉬를 활용하여 U-city의 인프라로의 역할 수행이 가능할 것으로 판단된다.
