Abstract

Wireless network solution is used in many area because of free mobility and easy of establishment. Sensors that compose wireless network need protocol that support wireless communication to share information each other. As representative protocol, we currently witnessed IPv6 protocol. However, due to the limitation of sensors's electric power and computing ability, it is inefficient that each sensors use this protocol. In this paper, we designed improved sensor circuit that can heighten energy efficiency in sensor network to solve these problem and composed algorithm that can pare down energy consumption using method to make unnecessary sensor in sleep-mode.

무선 네트워크 솔루션은 자유로운 이동성과 설치의 간편성 때문에 많은 영역에서 사용되고 있다. 무선 네트워크를 구성하는 센서들이 서로 정보를 공유하기 위해서는 무선통신을 지원하는 프로토콜이 필요하다. 대표적인 프로토콜은 Mobile IPv6가 있다. 그러나 각 센서들은 제한된 전력과 컴퓨팅 능력을 갖기 때문에 이 프로토콜을 사용하는 것은 매우 비효율적이다. 본 논문에서는 이러한 문제를 해결하기 위해 에너지 효율을 높일 수 있는 개선된 센서 회로를 설계하였으며, 센서 네트워크상에서 필요하지 않은 센서를 휴면상태로 둠으로써 에너지 소비를 줄일 수 있는 알고리즘을 구성하였다.
