IP has been designed for Internet decades ago to connect computers and share expensive resources such as tape drives and printers. Nowadays, Internet of Things and other emerging applications use Internet to fetch and exchange content such as monitoring data and movies. This content-centric use of Internet highlights the limitations of the IP architecture. IETF Working Groups spend significant efforts to adapt the traditional IP stack to IoT systems, but the shortcomings of IP remain difficult to hide. In this context, the recently emerged Named Data Networking (NDN) architecture promises a better support of IoT systems and future Internet applications. This paper describes a realistic IoT architecture based on NDN. In practice, an integration of NDN in IoT devices over low-power wireless technologies is designed, deployed and evaluated considering a Smart Farming application scenario. This work aims to show that NDN is more suitable than IP for IoT systems, by giving another look at IP-based solutions for the IoT such as 6LoWPAN. For that, we design a simple packet compression scheme and a lightweight forwarding strategy that is compliant with the NDN vision while managing constrained devices. Evaluation result demonstrate the flexibility of NDN to support IoT environments.
