We expect around 9 billions people on the Earth within 2050, 70% of them living in urban environments. By that time, we have to be ready to support a never seen request for ICT services in order to improve the efficiency of future Smart Cities, thus allowing a pacific coexistence among humans. In line with this premise, the present contribution proposes a novel service platform, based on the emerging content-centric networking paradigm. It can easily embrace all available, upcoming, and remote generation wireless techologies, while supporting, at the same time, ubiquitous and secure applications in many domains, such as: e-helthcare, intelligent transportation systems, entertainment, and many others. All details of the approach we propose, have been carefully described by means of pragmatical use-cases, thus making evident its effectivenes in future realistic urban environments.

The information centric paradigm assumes that the Future Internet will be built around contents rather than host locations. In this direction, the promising Content Centric Networking (CCN) architecture has been conceived to solve the problems of the today Internet by means of a novel way for distributing contents (based on their names) and by adopting distributed caching mechanisms. CCN can be particularly beneficial in an ad hoc networking environments, where the main goal is the delivery of data to a given destination node no matter its position, and moreover, in scenarios characterized by limited connectivity, just as wireless ad hoc networks. Some interesting works, available in literature, propose the exploitation of CCN paradigm in Mobile Ad hoc Networks or Vehicular Ad hoc Networks. Our contribute, here, is to provide the scientific community with a new fully customizable and open source emulation platform, named CCN-Joker, well-suited for wireless devices with limited resources. The rationale of the developed tool entails an application-level overlay. It is composed by several modules interacting with the data structures which a CCN node is commonly made of. We also conduct some preliminary experiments in a small overlay (composed by six EFIKA powerPC boards, equipped by a Wifi external card), analyzing the content distribution process, the hit ratio, and the average download time. These preliminary results confirm the suitability of CCN-Joker to study the CCN performance in Mobile Ad hoc Networks or Vehicular Ad hoc Networks.

In recent years the new vision of data-centric net works has emerged as a natural way to satisfy user needs in the Future Internet. It is based on novel architectures oriented towards data sharing and delivering as opposite to classic host-to host communications. Among several proposals, Content Centric Networking has been conceived as a very promising solution by the Palo Alto Research Center team. It can be gradually deployed over current IP networks and solves different problems, as NAT Traversal, depletion of IP addresses, security, mobility, and multicast communications. In this work an analytical frame work for investigating properties of Content Centric Network is proposed, with a particular focus on fairness in cache usage. It captures the distribution of content replicas among nodes of the network by taking into account contents availability, data popularity, topology information, and cache size. Preliminary results, validated using numerical simulations, shed some light on the underlying fairness of a Content Centric Network, thus helping future developments and upgrades on the current architecture.
