최근 산업현장에서 설치비 및 유지보수비의 경쟁력이 앞선 무선 기반 데이터 전송 솔루션이 적용되고 있다. 하지만 산업현장에서는 저렴하면서도 신뢰성 높은 최적의 무선 솔루션을 찾지 못하여 고사양 HW를 요구하는 WiFi나 사용료를 지불하는 면허 대역 통신을 대신 사용하고 있는 것이 현실이었다. 우리는 이를 해결하기 위해 경량 디바이스에 탑재 가능한 IPv6 포함한 경량운영체제를 바탕으로 대규모 디바이스를 연동할 수 있는 국제표준 기반 시간 동기화 기반 채널 호핑 방식을 산업 환경에 맞게 제안 및 개발하였다. 산업현장을 모사한 환경에서 400대 이상의 디바이스를 사용한 테스트 결과 제안된 알고리즘이 5홉 이상을 지원할 수 있고 96% 이상의 데이터 전송 성공률을 달성할 수 있음을 확인하였다. 나아가 우리가 개발한 이 디바이스 플랫폼은 AMI 산업에 적용되어 상용화되었다.
