Inter-Vehicle Communication is expected to be widely adopted during the next years by the car industry, enabling Vehicle-to-Vehicle and Vehicle-to-Infrastructure communication targeting at safer commuting. Therefore, the research community have been working towards providing a robust communication solution that will interoperate with existing network infrastructure and will provide an effective way of communicating using location information. One of the proposed solutions is the GeoNetworking

... otocol, standardized by ETSI, using location based addresses and an IPv6 adaptation sublayer for communicating with the Internet. Several implementations of the protocol exist currently, however most of them are integrated in simulation environments, thus ignoring several factors induced when experimenting under real conditions. In this paper we present our own implementation of an ETSI compliant GeoNetworking protocol and its integration in the NITOS Future Internet facility that enables open and remote access to experimenters on a 24/7 basis. This is the first real implementation in an open wireless testbed, which offers to the research community high diversity in the configuration parameters of their ITS experiments. We further explain our extensions that enable real world testing of our protocol implementation and we finally evaluate our solution in a real large scale wireless setup.
