Abstract：Taking into account the energy optimization and performance enhancement of the Content Centric Networking (CCN) comprehensively, an energy optimized implicit collaborative caching scheme for CCN is proposed. In terms of the caching decision, energy saving account is utilized as the judgement, which is carried out on consumer's remote nodes preferentially, and the data packet is utilized to carry the information of recent upstream caching hops, so as to realize the implicit collaboration, thus reducing the caching space competition pressure of the consumers’ near nodes, improving the caching difference between nearby nodes. As for the caching replacement, the caching content with the minimum energy saving account is selected to be replaced, achieving the optimal energy consumption optimization effect. Simulation results show that, the caching scheme achieves better cache hit ratio and average routing hops, meanwhile, it reduces the network energy consumption effectively.
