In this paper we describe several approaches to address the challenges of the network of the future especially from a mobile and wireless perspective. Our main hypothesis is that the Future Internet must be designed for the environment of applications and transport media of the 21st century, vastly different from the initial Internet's life space. One major requirement is the inherent support for mobile and wireless usage. A Future Internet should allow for the fast creation of diverse network designs and paradigms and must also support their co-existence at run-time. We observe that a pure evolutionary path from the current Internet design is unlikely to be the fastest way, if at all possible, to address, in a satisfactory manner, major issues like the handling of mobile users, information access and delivery, wide area sensor network applications, high management complexity and malicious traffic that hamper network performance already today. We detail the scenarios and business use cases that lead the development in the FP7 4WARD project towards a framework for the Future Internet.
