무선랜에 대한 IEEE 802.11 표준이 개발되면서 공장, 플랜트, 기타 산업 환경에서 무선랜의 사용이 엄청나게 증가했습니다. 산업용 애플리케이션에서 무선 LAN 시스템은 안정적인 실시간 통신을 위해 높은 신뢰성을 요구합니다. 본 논문에서는 무선랜에서 URLLC(ultra-reliable low-latency communications) 구현을 위해 강력한 데이터 전송 구현에 기여하는 다중 액세스 포인트(AP) 다양성 방법을 제안합니다. 제안하는 방법은 IEEE 802.11 표준을 수정하거나 통신 자원의 오버헤드를 증가시키지 않고도 독립적인 전송 오류 및 충돌을 갖는 다중 경로의 다양성 효과를 얻을 수 있다. 수치해석을 통해 제안한 방법의 효과를 평가하고, 타당성을 입증하기 위한 프로토타입을 개발한 후, 공장 무선 환경에서 프로토타입을 활용하여 실험을 수행한다. 이러한 수치 평가 및 실험을 통해 제안된 방법이 신뢰성을 높이고 전송 지연을 감소시키는 것을 보여줍니다.

Abstract: With the development of the IEEE 802.11 standard for wireless LANs, there has been an enormous increase in the usage of wireless LANs in factories, plants, and other industrial environments. In industrial applications, wireless LAN systems require high reliability for stable real-time communications. In this paper, we propose a multi-access-point (AP) diversity method that contributes to the realization of robust data transmissions toward realization of ultra-reliable low-latency communications (URLLC) in wireless LANs. The proposed method can obtain a diversity effect of multipaths with independent transmission errors and collisions without modification of the IEEE 802.11 standard or increasing overhead of communication resources. We evaluate the effects of the proposed method by numerical analysis, develop a prototype to demonstrate its feasibility, and perform experiments using the prototype in a factory wireless environment. These numerical evaluations and experiments show that the proposed method increases reliability and decreases transmission delay.
