Abstract

Recently, in order to improve the energy efficiency of WSN(Wireless Sensor Network), widely research have teen carried on. But, up to the present, Majority of methods are based on direct communication between CH(cluster head) and sink node, and based on the assumption that node can regulate signal energy actively according to the distance between nodes. So it's hard to implement those methods. Based on the theory that node has fixed radio wave radius, this paper present a multi leveling routing protocol. According to the simulation of the presented protocol, we have proved the energy saving efficiency and the implementation in real WSN.

최근 무선 센서 네트워크(WSN : Wireless Sensor Network)의 에너지 효율성을 높이기 위한 다양한 연구가 진행되고 있다. 그러나 지금까지 제안된 기법들은 일반 센서노드에서 싱크노드로의 직접통신이나 인접 센서노드 간에 발송에너지를 발송거리에 따라 능동조절 가능 등 가정들을 기반으로 하고 있어 이런 기법들은 실제 실현하기 어렵다. 이 논문에서는 모든 센서 노드들은 일정한 전파범위와 데이터 전송률이 유지한다고 가정을 기반으로 다단계 라우팅 기법을 제안한다. 시뮬레이션을 통하여 제안기법이 기존기법보다 에너지 효율이 향상되었고 또한 실제 무선센서네트워크 적용하기 용이함을 입증하였다.
