초록

지그비는 저 전력, 저 비용, 낮은 데이터 전송 속도의 특징을 가지는 무선 개인 망(Low Rate Wireless Personal Area Networ: LR-WPAN)의 표준이다. 방향성 메시징 기법은 방송을 사용하는 무선 센서 네트워크에서 방향정보를 가지는 메시지를 특정 영역으로 전송함으로써 중복 메시지 전송을 줄이는 것을 통하여 에너지 효율성을 높이는 프로토콜이다. 본 논문에서는 에너지 효율성 향상을 위하여 방향성 메시징을 지원하도록 수정한 지그비를 사용하는 실험용 격자형 센서 네트워크를 설계하고 구현한다. 본 논문의 실험용 센서 네트워크는 방향성 정보를 사용하도록 수정한 ADV 메시지와 라우팅 관리 모듈을 지원하는 Nano-24 노드로 구성한다. 실험용 센서 네트워크의 에너지 효율 향상성은 실제 ADV 메시지 전송에 따른 실험 결과 분석울 통하여 나타내 보인다.

ZigBee is the low power, low cost and low data rate wireless personal area network(LR-WPAN) standard. The Directed-Messaging is the protocol which improves the energy efficiency through reducing the redundant message transmission by transmitting messages with directional information toward the specified sub-network area in wireless sensor network using broadcasting. In this paper, we design and implement the experimental grid sensor network using ZigBee modified by the Directed-Messaging for the energy efficiency improvement. The experimental sensor network in this paper is configured with Nano24 supporting the ADV message and the routing management module modified to use the directional information. The energy efficiency improvement of the experimental sensor-network by evaluating the experimental results according to transmitting ADV message.
