Enabling IP geomulticast services for vehicular networks

The main purpose of vehicular networks is to improve safety and traffic efficiency. Geographic addressing and routing is currently the basic architecture solution adopted in most vehicular architectures and standards. However, it is also required that these vehicular architectures support the provision of additional IP based services and applications. One of these services is geo-enabled IP multicast, allowing to send traffic to some specific user groups within a geographic destination area; this is known as IP geomulticast. This paper presents a solution that allows the deployment of IP geomulticast services over the standardised architecture of the Car-to-Car Communication Consortium.
