Abstract
An intensive effort is presently carried out in order to research and develop vehicular communication systems. Several standards, prototypes and field operational tests are under deployment all around the world, involving multiple research centers and vehicle and electronics manufacturers. However, some research lines are open today, in which vehicular communication systems with guaranteed reliability and robustness are necessary. One of these challenges is the development of an effective GeoNetworking in vehicular communications. This concept means that the vehicle ad-hoc network (VANET) bases the data package transmission in the topographical location of the different nodes (vehicles) of the network, organizing the data flow in an optimal way that covers the surroundings of each vehicle. The core of this GeoNetworking system is the GeoRouting algorithm, that supports the optimal routing of the data packages and reorganizes the network structure in function of the positions of the nodes. In this paper we present a novel GeoRouting algorithm, based in the evolution of previous results of mesh vehicular networks. This algorithm has been designed, implemented and tested in real vehicles in real roads with free flow traffic. The results suggest that the features of the designed routing algorithm can be applied as core of any kind of vehicular network to support ADAS applications.
