Abstract

In recent years, IoT device and platform become widely popular and the computing performance and capabilities of IoT devices are also getting improved. However, the size and computing resources of IoT devices, especially small single board computer, are limited in a way that the design and implementation of the system should be carefully considered to operate on the devices. Recently, SDR technologies are adapting in IoT devices and can perform various radio systems. Thorough analysis and investigation of computer performances on small single board computer are necessary for its usage. In this paper, we present the results of computing resources measurement and analysis on small single-board computers. At first, we consider to design SDR based spectrum sensing for single board computer, investigate various key factors and propose a design procedure that can affect performance of the system with experiments.

최근 IoT 기기 및 플랫폼들의 발전 및 확장과 더불어 IoT 관련 기기 내 연산 성능도 지속해서 향상하고 있다. 그러나 기기 향상과는 별개로 IoT 기기, 특히 소형 단일 보드 컴퓨터의 제한적인 크기 및 연산 자원은 해당 기기 내 통신 시스템 구현 설계를 위한 중요 고려사항 중 하나이다. 현재 다양한 무선 통신 시스템을 활용할 수 있게끔 소프트웨어 정의 라디오 (SDR) 기술을 IoT 기기에 적용 시 소형 단일 보드 컴퓨터의 하드웨어 제한 사항으로 인한 열화 가능성으로 인하여 실제 시스템의 원활한 적용을 위해 해당 컴퓨터 성능에 대한 분석 및 조사가 필요하다. 본 논문에서는 소형 단일 보드 컴퓨터 내 SDR 적용 스펙트럼 센싱 시스템 디자인을 위한 시스템 연산 분석 및 실험을 진행한다. 먼저 단일 보드 컴퓨터를 위한 SDR 기반 스펙트럼 센싱 시스템을 설계하고 시스템 성능에 영향을 줄 수 있는 다양한 요소를 실험을 통해 조사하며. 이를 통한 중요 고려사항 및 디자인 가이드 절차를 도출한다.
