Abstract
The original Content Centric Network (CCN) em- ploys a simple caching scheme, Leave Copy Everywhere (LCE). However, this scheme is not efficient because cache redundancy reduces the storage capacity of the CCN network. In this paper, to resolve the issue of cache redundancy, we propose a cooperative caching decision and forwarding mechanism which is based on consistent hashing and virtual routers. We divide the Autonomous System (AS) into several groups of routers. The routers in the group cooperatively store the contents (Data) and also forward the requests (Interest) cooperatively in order to increase the caching performance of the CCN network. Finally, we evaluate our proposal by using a chunk-level simulator. The results show that the cache hit ratio of our proposed scheme is better than other proposed schemes. Keywords—Cooperative Caching,Content Centric Network, For- warding, Consistent Hashing, Virtual routers, Content popularity.
