Abstract

A Wireless Sensor Network (WSN) is better than a conventional network for use in construction and Operations and Maintenance (O&M) because of its lower surveillance system cost. However, effective operation of a WSN is often difficult to obtain because the surveillance targets are usually fixed inside the building or underground. Therefore, this environmental constraint should be considered in the design of the WSN plant equipment surveillance system prior to installation. This study employs simulations of WSN-based fixed facility surveillance using the TinyOS TOSSIM simulator to investigate ideal types and setups of the WSN. Simulation target protocols included LEACH and flooding and gossiping protocols. The results show that the hierarchically-structured LEACH protocol demonstrated better load-balancing and efficiency than the flatly-structured flooding and gossiping protocol.

무선센서네트워크는 구축과 운영측면에서 기존 네트워크방식보다 유리하나 각종 산업플랜트의 중요감시 대상설비는 대부분 건물내부 또는 지하에 위치하며 고정되어있어 일반적인 형태로는 적용이 어렵다. 이러한 특정 환경의 설비 감시를 위해서는 해당 조건에 적합한 무선센서네트워크 형태로 적용해야 한다. 따라서, 본 논문에서는 적합한 형태 확인을 위해 TinyOS시뮬레이터인 TOSSIM을 이용하여 고정설비감시 네트워크 환경과 유사한 조건에서 시뮬레이션을 수행하고 그 결과를 제시한다. 확인 대상은 LEACH, Flooding 및 Gossiping 프로토콜로 네트워크의 부하분산과 효율 면에서 계층구조인 LEACH가 좀 더 우수함을 나타낸다.
