초록

최근 주목을 받고 있는 Information Centric Network 구조 중 하나인 Content Centric Network (CCN)을 무선망에서 실질적으로 운영하기 위한 연구가 활발히 진행 되고 있다. 무선망에서 CCN을 운영을 위한 연구 결과들 중 가장 주목할 만한 것으로 Enhanced-Content-centric multiHop wireless NETwork(E-CHANET)이 있다. E-CHANET은 무선망의 특성을 고려하여 효율적 데이터 전송을 위한 방법을 제안하고 있다. E-CHANET에서는 하나의 데이터 파켓 전송 요청을 위하여 Interest 파켓을 전송하여야만 한다. 본 논문에서는 Interest와 데이터 파켓의 전송에 대한 효율성에 대하여 시뮬레이션을 통해 한번의 Interest로 모든 데이터 파켓을 전송하는 방식과 비교 분석하였다. 시뮬레이션 결과를 통하여 E-CHANET의 방식이 신뢰성을 증가시키기는 하나 전 파켓의 다운로드 시간을 많이 증가 시켜 비효율성이 있음을 확인하였다.

Content Centric Network (CCN) is one of candidate technologies for the future Information Centric Networks. Recently, adopting CCN concept to wireless networks has extensively been studied. One of the well-known studies is Enhanced-Content-centric multiHop wireless NETwork (E-CHANET), which proposes efficient methods to deliver contents adopting CCN concept over wireless environment. In E-CHANET, in order for a provider to send a data packet, one interest packet from a consumer is required. In this paper, efficiency of data-interest handshaking in E-CHANET has been investigated. It is compared with a method using only one interest packet for all data packets through simulations. As results, while the handshaking provides transmission reliability, it increses content down load time too much.
