Study of connectivity aspect of connected car

The connectivity have become the most important factor to users, by developing the car designed for mobile devices, in fact the connectivity modules will be installed in all cars, network providers have improved new infrastructure and technologies to receive connected cars, the connected car will be shared with other vehicles, distributors and teleinformatic services, this operation can lead to an increase in vehicle modules, difficulties and fragility, the automotive industry is moving towards autonomous cars. A recent technology and a range of recent products resulting from this are vehicle-to-vehicle (V2V), for the routing of data at V2V technology level there are different modes, strategies and routing protocols, the following article presents some definitions on the car connected the V2V communication, the different wireless communication technologies and wireless protocols used for V2V as well as the different routing protocols used and finally a comparison between these protocols.
