Cross-network information dissemination in VANETs

In this work, we provide an overview of an innovative approach for effective cross-network information dissemination, with applications to Vehicular Ad-hoc Networks (VANETs). In particular, we describe the main approach followed in an on-going bilateral Italy-Israel project (“Cross-Network Effective Traffic Alert Dissemination,” X-NETAD). The X-NETAD project leverages on the spontaneous formation of WiFi local VANETs, with direct connections between neighboring vehicles, in order to disseminate, very quickly and inexpensively, traffic alerts received from the UMTS network.
