Abstract

For transmitting sensed data, wireless sensor networks have been developed and researched for the improvement of energy efficiency, hence, many MAC protocols in WSN employ the duty cycle mechanism. Since the progressed development of the low power transceiver and processor let the high energy efficiency come true, the delivery of the multimedia data which occurs in area of sensor work should be needed to provide supplemental information. In this paper, we design a new scheme for massive transmission of large multimedia data where the duty cycle is used in contention based MAC protocol, for WMSN. The proposed scheme can be applied into the previous duty cycle mechanism because it provides two operation between normal operation and massive transmission operation. Measuring the buffer status of sender and the condition of current radio channel can be criteria for the decision of the above two operations. This paper shows the results of the experiment by performing the simulation. The target protocol of the experiment is X-MAC which is contention based MAC protocol for WSN. And two approaches, both X-MAC which operates only duty cycle and X-MAC which operates combined massive transmission scheme, are used for the comparative experiment.

WSN은 센서 탐지에 의한 데이터 전송을 목적으로 사용하며 이러한 송신 이벤트의 데이터 전송량은 일반적으로 용량이 작다. 이러한 이유로 일반적인 WSN MAC 프로토콜은 에너지 효율을 높이기 위하여 듀티 사이클 방식을 적용하지만, 이는 WMSN 환경에서 요구되는 대용량 멀티미디어 데이터 전송에 적합하지 않다. 본 논문에서는 WMSN 요구를 만족시키기 위하여 MAC 계층에서의 새로운 대용량 데이터 전송 기법을 제안하며, 기존 WSN 환경의 경쟁기반 MAC 프로토콜에서 도입하는 듀티 사이클 기법과 공존하여 적용할 수 있도록 설계하였다. 또한, 제안하는 대용량 데이터 전송기법은 송신 버퍼의 상태와 채널 환경을 고려하여 사용 유무를 결정하도록 설계되었으며, 송수신 노드가 대용량 데이터 전송 시점에서 이웃 노드에게 간섭받지 않고 채널 점유를 보장받을 수 있도록 설계되었다. 본 논문은 제안 방식의 객관적 성능을 평가하기 위하여 기존 듀티 사이클 기법을 지속적으로 운영하는 MAC과 제안하는 대용량 전송 방식을 혼용하여 운영하는 MAC을 모두 실험하고 그 결과를 분석하였다.
