Abstract

In this paper we propose a traffic aware Demand Wakeup MAC(TADW-MAC) protocol, in which low data delay and high throughput can be achieved, for wireless sensor networks. With the TADW-MAC protocol, the problem of the DW-MAC protocol, which schedules only one packet to deliver during the Sleep period in a multi-hop transmission is resolved. DW-MAC is not adequate for the applications such as object tracking and fire detection, in which busty data should be transmitted in a limited time when an event occurs [6-8]. When an event occurs, duty cycle can be adjusted in the TADW-MAC protocol to get less energy consumption and low latency. The duty cycle mechanism has been widely used to save energy consumption of sensor node due to idle listening in wireless sensor networks. But additional delay in packet transmission may be increased in the mechanism. Our simulation results show that TADW-MAC outperforms RMAC and DW-MAC in terms of energy efficiency while achieving low latency.

본 논문에서는 무선 센서 네트워크의 센서 노드들로부터 전송되는 데이터 트래픽에 따라 낮은 지연과 높은 데이터 효율을 지원하는 새로운 MAC 프로토콜을 제안한다. 본 논문에서 제안하는 TADW-MAC은 기존의 멀티 홉 전송에서 해당 Sleep 구간에서 오직 하나의 패킷 전송만을 스케줄할 수 있는 DW-MAC의 문제점을 해결하며, 물체 트래킹(object tracking)이나 화재 감시 시스템 등의 응용에 적합한 duty cycling 메커니즘을 가진다. 이러한 응용에서는 평소에는 데이터 전송이 이루어지지 않지만, 물체의 나타남과 화재 발생 등 이벤트가 발생하는 경우에는 많은 데이터를 전송해야 하며, 낮은 지연을 요구한다[6-8]. 따라서 TADW-MAC에서는 이러한 이벤트가 발생하였을 경우에 duty cycle을 조절함으로 보다 높은 효율과 적은 에너지를 소모할 수 있다. 여러 시뮬레이션을 통해 TADW-MAC은 기존의 RMAC이나 DW-MAC에 비해 에너지 효율과 전송 지연 면에서 더 나은 성능을 보여준다.
