Information-centric publish-subscribe mechanisms for Intelligent Transportation Systems

Emerging services for Intelligent Transport Systems put the information content at the centre of the communication process, require a seamless support of mobile users, and target a real-time and asynchronous data dissemination. The Information-Centric Networking paradigm has all the potentials to fulfill these requirements, thanks to its ability to distribute contents through publish-subscribe communication mechanism, also in mobile conditions. Unfortunately, most of publish-subscribe models proposed in the literature consider static scenarios. The work presented herein formulates two publish-subscribe schemes, based on the pull-based and push-based approaches, discusses their behavior through simplified examples, and evaluates the communication overhead they incur in realistic scenarios through computer simulations.
