Content-Centric Networking (CCN) recently received a lot of attention thanks to its elegant way to optimize content diffusion at the scale of Internet. However, communications occurring at the edge of Internet, in particular the Internet of Things (IoT), are also a vivid research topic. Even if CCN was not initially designed to optimize the specific traffic pattern of the IoT, it can be improved to better support these new applications. In this paper, we propose to optimize the traffic within a CCN for IoT network where information is created and consumed at different frequencies. The simulations show that our solution outperforms the vanilla CCN architecture for this generic scenario.
