- Abstract:
- Content-Centric Network is a new network paradigm. In this paradigm, contents are the main element of the network, and the place holding the content is transparent to users. In other words, the concept of content’s place is eliminated. In spite of other common paradigms in which caching operation is occurred in just a few predefined nodes and also it is limited to a specific application, in this kind of network, caching operation can be occurred in all nodes, independent of the application. Furthermore, due to elimination of the concept of the content’s place, matching of same contents held in different places can be possible. So caching in such networks became an important issue. In caching algorithms, the answer to this question where to cache each content, is the main challenge in Content-Centric Networks. In order to find the optimum state of this challenge, the number of references to each content is used. In this article, the weakness of this parameter in optimization is reviewed. A new parameter and also an algorithm based on prediction of contacts between nodes and Social Networkswill be introduced. Furthermore, the problems of inconsistency and lack of performance due to single-copy caching or filling network resources by uncontrolled multi-copy caching is reviewed and solved
