Abstract

To resolve inefficient content delivery mechanism in conventional internet-based networks, Content-Centric Networks (CCN) has been proposed for wired and wireless networks. One of issues in wireless CCN-based networks is overhead to achieve reliability on content delivery because CCN uses end-to-end two-way handshake with Interest/content packets. In this paper, a novel protocol to reduce overhead and achieve reliability is proposed. The protocol allows Interest packet to request multiple data packets and multiple data packets to be sent in a row without a Interest packets. The protocol is evaluated through the simulations and the performance improvement is proved.

종래의 인터넷 기반 네트워크에서 비효율적 콘텐츠 전달 메커니즘을 해결하기 위해 콘텐츠 중심 네트워크(CCN)은 유선 및 무선 네트워크를 위해 제안되었다. 무선 CCN 기반 네트워크의의 문제 중 하나는 콘텐츠들의 전송에 대한 신뢰성을 달성하기 위해 Interest-Data 기반의 핸드셰이킹(handshaking)을 종단 간에 수행 합으로써 많은 오버 헤드가 발생하기 때문이다. 본 논문에서는 오버 헤드 감소 및 신뢰성을 달성하기 위해 다수의 데이터 패킷들이 Interest 패킷 없이 연속적으로 전송되도록 하는 프로토콜을 제안하였으며, 프로토콜을 통한 성능 향상을 시뮬레이션을 통해 입증하였다.
