摘要：

Recently, Internet energy efficiency is paid more and more attention. New Internet architectures with more energy efficiency were proposed to promote the scalability in energy consumption. The content-centric networking(CCN) proposed a content-centric paradigm which was proven to have higher energy efficiency. Based on the energy optimization model of CCN with in-network caching, the authors derive expressions to tradeoff the caching energy and the transport energy, and then design a new energy efficiency cache scheme based on virtual round trip time(EV) in CCN. Simulation results show that the EV scheme is better than the least recently used(LRU) and popularity based cache policies on the network average energy consumption, and its average hop is also much better than LRU policy.
