In vehicular networks, safety and comfort applications are two quite different kinds of applications to avoid the emergency traffic accident and enjoy the non-emergency entertainment. The comfort application drives the challenges of new non-emergency entertainments for Vehicular Ad-hoc NETworks (VANETs). In this paper, the authors investigate a new mobicast protocol to support comfort applications for a highway scenario in Vehicular Ad-hoc NETworks (VANETs). All vehicles located in a geographic zone (denoted as zone of relevance, ZOR) at time t, the mobicast routing is to disseminate the data message initiated from a specific vehicle to all vehicles which have ever appeared in ZOR at time t.
