C-ITS is a research field that looks to generate complex ad-hoc networks in which the nodes themselves must think on their own and where any connected node must help the nodes around to know and understand how the network works at any moment and also to preview how it must behave from one second to the next one in order to solve traffic management problems and accidents as fast as possible. The main objective of this project is to evaluate two protocols belonging to the ETSI protocol stack (802.11p and GeoNetworking) through a simulation software based on Omnet++. By using multiple parameters like propagation models, loss probability and some others, some results are presented to evaluate whether the two protocols fulfil the network requirements or not. At the end of the project an improvement proposal for one of the two defined services is presented.
