Abstract

A number of on-demand routing protocols for sensor networks have been proposed yet. However, the majority of proposed on-demand routing protocols for sensor networks are not suitable for a relatively poor wireless environment and sensor applications requiring reliable data transmission due to using a hop-count metric for their protocols. In this paper, we proposed a minimum LQI(Link Quality Indicator) based on-demand sensor network routing protocol that is suitable for a relatively poor wireless environment and implemented the proposed routing protocol on a TinyOS. We also compared the implemented protocol with typical hop count based routing protocol by carrying out performance experiments on a multi-hop testbed. The results from these experiments showed that the successful transmission rate of the proposed routing protocol is higher than that of typical hop count based routing protocol over a poor wireless link.

지금까지 다수의 센서 네트워크를 위한 on-demand 라우팅 프로토콜들이 제안되었다. 하지만 제안된 센서 네트워크용 on-demand 라우팅 프로토콜들은 대부분 hop count를 라우팅 메트릭으로 사용하기 때문에 상대적으로 열악한 무선 환경과 신뢰성을 요구하는 센서 응용에는 적합하지 않다. 본 논문에서는 이러한 환경에 적합한 minimum LQI(Link Quality Indicator) 기반의 on-demand 센서 네트워크 라우팅 프로토콜을 제안하였다. 또한 제안한 라우팅 프로토콜을 TinyOS 상에서 구현하였고, 멀티 홉 테스트 환경에서 hop count 기반의 라우팅 프로토콜과 성능을 비교, 측정하였다. 실험 결과, 제안된 라우팅 프로토콜이 열악한 무선 환경에서 더 나은 데이터 전송 성공률을 보임을 확인할 수 있었다.
