Abstract

This paper proposed an efficient multiple TCP mechanism using Android smartphones for remote control video Wi-Fi stream transmission via network communications in real time. The wireless video stream transmission mechanism can be applied in various area such as real time server stream transmissions, movable drones, disaster robotics and real time security monitoring systems. Moreover, we urgently need to transmit data in timely fashion such as medical emergency, security surveillance and disaster prevention. Our parallel TCP transmission system can play an important role in several area such as real time server stream transmissions, movable drones, disaster robotics and real time security monitoring systems as mentioned in the previous sentence. Therefore, we designed and implemented a parallel TCP transmission (parallel stream) for an efficient real time video streaming services. In conclusion, we evaluated proposed mechanism using parallel TCP transmission under various environments with performance analysis.

본 논문에서는 전 세계 스마트폰 기기 시장을 양분하고 있는 안드로이드 스마트폰을 이용하여 원격지에 있는 영상을 실시간으로 확인할 수 있는 시스템을 설계하고 제안하였다. 이 무선 영상 전송 시스템은 개인이 실시간 현지 상황을 서버에 접속한 단말들에 전달하거나 이동 가능한 드론, 로봇 차량 등의 장치에 설치하여 현장 확인, 영상을 통한 보안 감시로 이용할 수 있을 것이다. 보안 감시 및 재난안전 예방을 위해 데이터를 긴급히 보내야하는 경우도 있다. 이러한 이용 분야들에 적용하면 응급상태나 재난예방, 보안감시에 있어 중요한 역할을 한다. 따라서 효율적인 실시간 스트리밍 전송을 위해서 본 논문에서는 병렬 TCP 통신 (parallel stream)을 이용하여 구현하였다. 결론적으로, 병렬 TCP 통신을 이용한 시스템의 효과를 다양한 환경에서 평가하고 성능 분석도 하였다.
