Abstract

Recently, with the rapid increase in technology and users of smart devices, the smart watch market has grown, and its utility and usability are continuously expanding. The strengths of smartwatches are wearable portability, application immediacy, data diversity and real-time capability. Despite these strengths, smartwatches have limitations such as battery limitations, display and user interface size limitations, and memory limitations. In addition, there is a need to supplement developers and standard devices, operating system standard models, and killer application modules. In particular, monitoring and application of user's biometric information is becoming a major service for smart watches. The biometric information of such a smart watch generates a large amount of data in real time. In order to advance the biometric information service, stable peer-to-peer transmission of sensing data to a remote smartphone or local server storage must be performed. We propose a synchronization method to ensure wireless remote peer-to-peer transmission stability in a smart watch system. We design a wireless peer-to-peer transmission process based on this synchronization method, analyze asynchronous transmission process and proposed synchronous transmission process, and propose a transmission efficiency method according to an increase in transmission amount.

최근, 스마트기기의 기술 및 사용자의 급증과 더불어, 스마트워치 시장이 성장하고, 그 효용성 및 사용성이 지속적으로 확대되고 있다. 스마트워치의 강점은 웨어러블 휴대성, 응용의 즉시성, 데이터 다양성 및 실시간성 등이다. 이러한 강점에도 불구하고, 스마트워치는 배터리 제약, 디스플레이 및 사용자 인터페이스 크기 제약, 메모리 제약 등의 한계성을 지닌다. 또한, 개발자 및 표준 디바이스, 운영체제 표준 모델, 킬러 애플리케이션 모듈 등의 보완 필요성이 제기된다. 특히, 스마트워치는 사용자의 생체정보 모니터링 및 응용이 주요한 서비스로 자리하고 있다. 이러한 스마트워치의 생체정보는 실시간 대용량 데이터를 생성한다. 생체정보 서비스의 고도화를 위해서, 센싱 데이터를 원격 스마트폰 또는 로컬서버저장소로 안정적인 피어-투-피어 전송이 수행되어야 한다. 본 연구는 스마트워치 시스템에서 무선 원격 피어-투-피어 전송 안정성을 보장하기 위한 동기화 방법을 제안한다. 이러한 동기화 방법에 기초한 무선피어-투-피어 전송 프로세스를 설계하고, 비동기 전송 프로세스와 제안 동기 전송프로세스를 분석하여 전송량 증가에 따른 전송 효율화 방법을 제안하다.
