Recently, researches to adopt Content-centric network (CCN), which is one of the promising technologies for replacing TCP/IP-based networks, to wireless networks has actively performed. However, because of erroneous and unreliable channel characteristics, there are many problems to be resolved to adopt CCN to wireless networks. This paper proposes a method to reduce content download time because nodes possess only parts of content chunks. The proposed method enables a node having parts of content chunks to request the rest of parts of content chunks to a provider before a Consumer requests the content. As a consequence, the content download time is reduced. |
