초록

본 논문은 센서 네트워크상에서 지연시간에 민감한 데이터 전송을 위한 에너지 효율적인 MAC 프로토콜을 제안한다. 비 동기식 센서 네트워크에서는 소비되는 에너지와 지연시간이 채널 모니터링 주기(Channel Monitoring Interval)와 데이터 센싱 주기(Sensing Data Interval)에 따라 변화한다. 이러한 사실을 기반으로 본 논문에서는 오버히어링(Overhearing)으로 발생하는 에너지 소비를 줄이기 위해 자신의 채널 모니터링 주기를 이웃노드에 알리는 새로운 프리엠블 구조와 낮은 연산 복잡도를 가지는 채널 모니터링 주기를 결정하는 알고리즘을 제안한다. 실험결과에서는 다른 센서 MAC 프로토콜과 제안한 MAC 프로토콜과의 성능비교를 보여준다.

This paper presents an energy efficient MAC protocol for delay-sensitive data transmission over wireless sensor network. In general, energy consumption and delay depend on Channel Monitoring Interval and data sensing period at each sensor node. Based on this fact, we propose a new preamble structure to effectively advertise Channel Monitoring Interval and avoid the overhearing problem. In order to pursue an effective tradeoff between energy consumption and delay, we also develop a Channel Monitoring Interval determining algorithm that searches for a sub-optimal solution with a low computational complexity. Finally, experimental results are provided to compare the proposed MAC protocol with existing sensor MAC protocols.
