“…A mobile device in a UWCN instead will be able to know its position not only based on GPS coordinates (kept local), but also on the surrounding UWCN APs, and the local services available can be simply located on the APs themselves. Some people claim that the density of APs is simply not enough, but a look at the few works as [4] that have really analysed the potential tells a different story.…”

Is a different (from the global Internet and Cellular Networks) model for urban communications and networking conceivable? Can Community Networks, now flourishing in many parts of Europe and the world, be the next 'big thing' in networking, for once considering the needs of people and urban evolution as a key element, and not as a side effect of technology or business? This paper discusses recent evolutions of Community Networks in Urban Areas, blending the technical analysis of their topology and evolution, together with grand challenges ahead and the need for a novel, transdisciplinary science that can guide the design of the future communication space for smart cities and beyond.

“…Most discoverable access points are password-protected, and some enforce an authentication or registration via portals. Even if a user on-the-move is lucky enough to find a free usable AP, it is unable to serve persistent connections for him due to its finite radio coverage [23].…”

Geospatial information is gaining immense interest and importance as we enter the era of highly developed transportation and communication. Despite the proliferation of cellular network and WiFi, on some occasions, users still face barriers to accessing geospatial data. In this paper, we design and implement a distributed prototype system with a delay/disruption tolerant network (DTN), named Geo-DMP, for cooperatively and opportunistically sharing and exchanging named geospatial contents in a device-to-device fashion. First of all, we construct a lightweight “content agent” module to bridge the gap between the application layer and the underlying DTN protocol stack. Afterwards, to profile the mobility history of users in practical geospatial environments, we present a map segmentation scheme based on road network and administrative subdivision information. Subsequently, we associate the regional movement history information with the content retrieval process to devise a hierarchical and region-oriented DTN routing scheme for both requests and responses. Finally, we conduct extensive experiments with real-world trajectories and complete implementations on the emulation platform composed of virtual machines. The experiments corroborate that Geo-DMP has the capability of successfully retrieving geospatial contents for users for most of the time under mobile circumstances with episodic connectivity. Moreover, en-route caches can be efficiently exploited to provision contents from multiple sources with less network resource consumption and shorter user-perceived latencies.
