Abstract

As users generate lots of contents independently of time and places anytime and anywhere together with a rapid development of mobile wireless communication technologies and an explosive dissemination of smart devices, content centric networking (CCN) has emerged as a new networking architecture. However, as CCN is based on one to one message exchanges, it is not appropriate for ad hoc network environment that has frequent network topology changes, which results in high control overhead and low transmission throughput. So, this paper proposes the new content sharing methods using group interest messages in CCN ad hoc environment. It is shown from the simulation that the proposed method can provide low control overhead and high transmission throughput.

무선 이동 통신 기술의 급속한 발달과 스마트 기기의 폭발적 보급으로 사용자들이 시간과 장소에 구애받지 않고 자유롭게 콘텐츠 생성과 공유를 시도함에 따라, CCN과 같은 콘텐츠 중심의 새로운 네트워킹 방식이 등장하게 되었다. CCN은 일대일 전송 구조를 근간으로 하고 있어 네트워크 토폴로지 변화가 빈번한 ad-hoc 환경에서는 많은 오버헤드 발생 및 낮은 전송 효율을 갖게 된다. 이에 본 논문에서는 ad-hoc 네트워킹 환경에 적합하도록 CCN 그룹 콘텐츠 전송방식을 제안한다. 성능 평가를 통해 제안 방식이 기존 방식 대비 제어 메시지 오버헤드 감소 및 전송 효율을 크게 향상시킴을 확인하였다.
