In view of evolving the Internet infrastructure, Information-Centric Networking (ICN) is promoting a communication model, which is fundamentally different from the traditional IP address-centric model. The ICN approach consists in the retrieval of content by (unique) names, regardless of origin server location (i.e., IP address), application and distribution channel, thus enabling in-network caching/replication and content-based security. The expected benefits in terms of improved data dissemination efficiency and robustness in challenging communication scenarios, claim the high potential of ICN as an innovative networking paradigm in the Internet of Things (IoT) domain. IoT is a challenging environment, mainly due to the high number of heterogeneous and potentially constrained networked devices, the unique and heavy traffic patterns. The application of ICN principles in such a context opens new opportunities, while requiring careful design choices. This article critically discusses potential ways towards this goal, by surveying the current literature, after presenting several possible motivations for the introduction of ICN in the context of IoT. Major challenges and opportunities are also highlighted, serving as guidelines for progress beyond the state of the art in this timely and increasingly relevant topic.
