Cache Replacement Mechanism with Content Popularity for Vehicular Content-Centric Networks (VCCN)

摘要

Caching mechanism is usually used in Content-Centric Networking. Cache data is contained at provider node and all nodes along the path to the consumer node. The disadvantage of this mechanism is the data redundancy on several nodes. In the case of the cache size is limited, the cache hit of the request data is issued. In this paper proposed a Cache Replacement with Content Popularity (CRCP) mechanism that allows a node in a cluster of vehicles to make decision retaining data or performing cache replacement. The results demonstrate the performance of the proposed mechanism is better than the LFU and LRU in terms of average cache hit ratio.
