چکیده انگلیسی

Content Centric Networking (CCN) is a new network architecture around content dissemination and retrieval. Its request–response and in-network caching mechanisms can significantly improve the network performance in reducing the transmission delay. However, the in-network caching may prevent the network coding technique from being applied into CCN because cached coded blocks may not be linearly independent to each other such that they cannot be used for responding the future requests. In this paper, we propose a novel request-specified network coding (RSNC) scheme for efficiently encoding and delivering chunks of content. In this scheme, a new Interest coding and forwarding strategy is proposed for specifying network coding requirements and getting linearly independent coded blocks simultaneously from multiple nodes. Our simulation results show that the proposed scheme achieves better performance than conventional CCN in terms of average download time, cache hit ratio, and transmission amount.
