Green Named Data Networking Using Renewable Energy

While communication technologies are evolving rapidly, there is still the nontrivial matter of our communication system being green. In this paper, we propose a new green approach for Named Data Networking (NDN) where content requests and caching perform towards greener content delivery. We design a forwarding and caching strategy, where we first define the greenness of nodes and identify corresponding green paths, then encourage traffic to aggregate on green paths powered by more eco-friendly renewable energy. We validate our solution with a variety of simulations using real network topologies and renewable energy statistics from the US, and the results show that applying the proposed green NDN strategy achieves significant gains.
