The energy footprint of Content-Centric Residential Community Networks

The paper presents a comparison between various approaches to the optimized operation of a Content Centric Residential Community Network (CCRCN). The evaluation basis is mostly about the energy footprint of CCRCNs, but other factors, such as content offloading and Internet Sharing, are also taken into account. From the analysis it emerges that the current approaches to operate a CCRCN are not very profitable in terms of energy. Some produce very marginal savings, whereas the behaviour of others is strongly dependent on the operational conditions, thus being scarcely predictable. We thus point out the strengths and weaknesses of each, thus paving the way for the future greening strategies of CCRCNs.
