Abstract

Nowadays, Content Centric Networking (CCN) could be the future Internet architecture for its advance feature: In-network caching due to cheaper to cache than to transmit contents nowadays. Besides, the popularity of content in CCN gives much challenge to researchers, but there are a few solutions for that, such as LCD (Leave Copy Down). LCD policy is known as simple and effective caching mechanism so far. This work presents a new way of cooperation between CCN nodes in caching mechanism. Our caching mechanism is an optimization of LCD that some CCN nodes can help the others for their work on caching decision policy. This cooperation method doesn’t require both additional signaling packet and much computation resource to work. Experiments show that this optimization in terms of cache hit can achieve better than convention LCD does. In additional, our solution is simple and very low overhead.
