Fine-Grained Tracking of Human Mobility in Dense Scenarios

This paper envisions an urban scenario where people carry radio devices that can be dynamically networked, by exploiting human contact opportunities, to create unplanned, improvised and localized wireless connectivity, which has been recently called Pocket Switched Networks (PSNs). PSNs are a subclass of Delay Tolerant Networks, but the fascinating idea of considering people as the switching nodes of a mobile network infrastructure is progressively moving the application of DTN from rural, or deep space, to urban scenarios where nodes are more densely distributed, and people contacts are more frequent and dependent on their social relationships.
