Abstract

As the performance of the next-generation broadband wireless networks is dramatically enhanced, various services (i.e., education, video conferencing, online games, etc.) have been provided to users through a smart mobile platform. Since those services are usually provided by using the centralized architecture, it is difficult for a lot of users to provide the scalable communication service with regard to traffic management. To solve these problems, we have proposed an architecture of P2P-based group communication management scheme using smart mobile device. More specifically, we design the group management protocol and algorithm for the group member management and the traffic management. By using these methods, the mobile multimedia streaming service can be provided with scalability. In order to verify the performance of the proposed scheme, we have mathematically analyzed the performance in terms of the average transmission delay and bandwidth utilization.

차세대 광대역 무선 네트워크의 성능이 급격히 증가함에 따라 스마트 모바일 플랫폼 기반으로 다양한 서비스 (교육, 비디오 컨퍼런싱, 온라인 게임 등)가 사용자에게 제공되고 있다. 하지만, 대부분의 이러한 서비스들은 중앙 집중식 구조로 서비스가 제공되고 있기 때문에, 트래픽 관리에 대한 확장성 있는 통신 서비스를 제공하는데 어려움이 있다. 기존의 이러한 문제점을 해결하기 위해, 본 논문에서는 스마트 이동 단말을 이용한 P2P 기반 그룹 통신 관리 서비스 구조를 제시한다. 좀 더 구체적으로, P2P 기반의 그룹 사용자 관리와 트래픽 관리를 위한 그룹 통신 관리 프로토콜과 알고리즘을 설계하였다. 제안된 방법을 통해 확장성 있는 멀티미디어 스트리밍 서비스를 사용자에게 제공할 수 있다. 이를 증명하기 위해 평균 전송 지연시간 (Average Transmission Delay) 및 대역폭 이용률 (Bandwidth Utilization) 에 대한 수학적인 분석을 수행하였다.
