International audience; The difficulties associated with network connectivity, unreliable channels, and city environment characteristics make data dissemination task in vehicular urban networks a real challenge. Recently, some interesting solutions have been proposed to perform data dissemination in this environment. Starting from the analysis of these solutions, we present a new dissemination protocol named DHVN (Dissemination protocol for Heterogeneous Cooperative Vehicular Networks) that considers: (i) roads topology, (ii) network connectivity and possible partitioning in case of low traffic density, and (iii) heterogeneous communication capabilities of the vehicles. We compare our protocol to other dissemination protocols and analyze its performances using NS-3 simulator [1]. Performance studies show interesting DHVN compared to existing solutions. Indeed, DHVN is able to provide a low end-to-end delay, a high delivery ratio and a minimum bandwidth usage since only a limited number of vehicles are involved in the broadcast scheme.
