People on the move are typically interested in information with
respect to their proximity. Location-based services in general
supply users with information about their proximity typically
relying on an infrastructure storing the information and tracking
the mobile objects, i.e. users. In this paper we present an approach
for spontaneous, i.e. ad hoc, networks inspired by the Usenet.
Information is exchanged using a peer-to-peer synchronization
mechanism. The information is made available through channels
grouping related information. The information propagation is solely
based on spontaneously connected devices not requiring any
infrastructure. Our prototype implementation shows the technical
feasibility of our approach, whereas simulation results show the
applicability of information diffusion in outdoor scenarios with a
realistic number of nodes, covering a city center.
