Abstract: In this paper we consider information dissemination in vehicularad-hoc networks (VANETs) in city scenarios. Information disseminationis an important building block of many proposed VANETapplications. These applications need a certain disseminationperformance to work satisfactorily. This is critical during therollout of VANETs, when only few cars participate. After analyticalconsiderations, we focus on simulations using a detailed model of awhole city. We assess the dissemination performance depending on theamount of equipped vehicles on the road. For few equipped vehicles, weshow that dissemination speed and coverage will not be sufficient.Therefore, we propose to use specialized, but simple and cheapinfrastructure, Stationary Supporting Units (SSUs). If asmall number of SSUs is installed in a city and connected via somebackbone network, the dissemination performance improves dramatically,especially during the VANET rollout phase. Thus, SSUsallow for a faster and earlier rollout of working, dissemination-basedVANET applications.
