In-network caching for CCN (Content-Centric Networking)is expected to achieve an adaptive content delivery in the network and to reduce traffic by storing content data on each router. Reducing traffic is also important because power consumption in networks has been increasing yearly year. Therefore, in-network caching is beneficial in view of energy-efficiency. However, in order to improve energy efficiency of the network, it is necessary to cache content appropriately in consideration of both power consumption of content caching and transmission of traffic. Moreover for a distributed cache framework such as CCN, content caching should be autonomously controlled by distributed cache nodes. In this paper, we propose a distributed cache management mechanism to control energy-efficient cache locations of content. Furthermore, we demonstrate the effectiveness of the proposed mechanism by simulations.
