Abstract

In this paper, we propose a unique systolic structure and communication algorithm that maintains a solid link between nodes using synchronous digital communication and enables low power communication. This system was designed by using CC2500 RF transceiver, CC2590 RF front end and C8051F330 low power microcontroller. The measurement of power consumption in the network link shows below $400{\mu}W$ in data transfer rate 320bps. The system constitutes the base unit of low power wireless network that was composed of each seven link nodes having eight sensor nodes. Results of the experiments show that link nodes using a 4Ah battery could operate over 3 years without replacement.

본 논문에서는 동기식 디지털 통신 프로토콜을 사용하여 노드 간 견고한 링크를 유지하고 초 저 전력 통신을 수행할 수 있는 고유의 시스톨릭(systolic) 구조 및 통신 알고리즘을 제안한다. 이 시스템은 CC2500 RF 트랜시버, CC2590 RF 프론트 엔드 및 C8051F330 저 전력 마이크로컨트롤러를 사용하여 설계 및 평가 되었고 구현된 링크 노드의 전력소모는 320bps의 데이터 전송 속도에서 $400{\mu}W$ 이하로 측정되었다. 구현된 시스템은 각각 센서 노드 8개를 연결할 수 있는 링크 노드 7개로 구성된 저 전력 무선 센서 네트워크를 구성하는 기본 장치의 기능을 가지고 있다. 실험을 통해 링크 노드는 4Ah의 배터리를 사용하는 경우 4초의 주기로 3년 이상의 배터리 무교체 동작을 구현할 수 있다.
