Design of energy-efficient routing method for USN based Large scale Glass greenhouses

USN based Large Scale Glass greenhouses를 위한 에너지 효율적인 라우팅 방법

Recently, wireless communication technology and state of art miniaturization has enabled the wireless sensor network with Smart Environmental sensors. The sensor network is a new field which has been researched vigorously in the ubiquitous computing and Ad-hoc network. How to efficiently use the limited energy in this USN(Ubiquitous sensor Networks) has been debated recently. We utilized the Directed Diffusion and Gossiping concept which is based on the Large scale Glass greenhouse and present a method to prolong the lifespan of the sensor network by operating variable time based this routing information on the average energy leftover. In this paper, we present a method to minimize the energy consumption of sensor node within Glass greenhouses and ensure a stable network operation at the same time through energy efficient routing among sensor nodes.

Ad-Hoc 통신 기술과 더불어 무선 센서 네트워크(Ubiquitous Sensor Networks) 기술은 최근 관심이 집중되고 있는 유비쿼터스 컴퓨팅 시대의 핵심 기반기술로서 그 중요성이 점차 대두되고 있다. 이러한 WSN환경에서 제한된 에너지로 얼마나 효율적으로 네트워크를 운용하느냐가 최근 많은 이슈로 등장하고 있다. 본 논문에서는 Large Scale Class Greenhouse를 배경으로 센서 노드 간에 Directed Diffusion과 Gossiping concept을 바탕으로 라우팅 경로를 생성하고, 에너지 효율(energy-efficient)적인 경로 설정(routing)을 통하여 센서노드의 에너지 소모를 최소화하여 전체 센서 네트워크의 life-time을 연장하는 방법을 제안한다.
