초록

본 논문은 네트워크 전체의 전력 소모를 줄이기 위해 제어 패킷의 소모를 줄이는 비동기 센서 MAC 프로토콜을 설계한다. 기존 비동기 방식의 X-MAC은 너무 많은 제어 패킷을 보낸다는 단점, PW-MAC은 다중 송신자와 단일 수신자 상황에서 데이터 패킷이 충돌한다는 단점이 있다. 본 논문에서는 두 프로토콜의 단점을 보완하여 수신자 기반(Receiver-Initiated)으로 동작하며, 송신자에 의해 제어 패킷을 생성하는 MAC 프로토콜을 제안한다. 본 문에서 NS2를 이용한 실험의 결과를 통해 전력 소모, 전달 지연, 평균 처리량이 기존 연구에 비해 향상됨을 확인했다.

In this paper we describe an asynchronous MAC protocol with receiver-initiated duty cycling for energy-efficiency in wireless sensor networks(WSN). Legacy asynchronous MAC protocols, X-MAC and PW-MAC, has weaknesses which generates too many control packets and has data collision problem between multiple transmitters, respectively. Therefore, we propose a receiver-initiated asynchronous MAC protocol which generates control packets from transmitter to complement these disadvantages. Compared to the prior asynchronous duty cycling approaches of X-MAC and PW-MAC, the proposed protocol shows a improvement in energy-efficiency, throughput and latency from simulation results.
