Wind-Aware Content Caching for Smart Farm

In this paper, we propose a new sustainable approach for content-centric networking (CCN) where content caching performs towards wind-aware content delivery. We design a caching strategy, where we first define the windiness of nodes, a quantitative metric for measuring the available power generation from wind turbines, based on which we identify corresponding windy paths and encourage content to aggregate on windy paths powered by more wind energy. We validate our approach with a variety of simulations using real smart farm testbed topology and its meteorological datasets from Rep. of Korea, and the results show that applying the proposed wind-aware caching scheme achieves significant gains by reducing existing fossil-fuel energy.
