From theory to reality: testing an accident warning system on a real highway scenario

In this paper we will describe recent research that has addressed the particular problem of assessing the performance of Vehicular Ad Hoc Network-based accident warning systems for highway scenarios. The authors of the cited works have shown that it is possible to recreate the conditions that would be experienced in reality implementing a virtual overlay network on top of a few cars. In particular, when testing an accident warning system specifically designed for highway scenarios, it has been possible to experience and observe alert messages that propagated up to 20 km away from the origin.
