# A 5G V2X Ecosystem Providing Internet of Vehicles +
## 7 Conclusions  
The 5G networks have several challenges to fulfill the IMT-2020 standard requirements. They must suit the new characteristics of the new network model in the operational level. The high complexity expected from a heterogeneous 5G V2X network architecture, together with the imposed challenges for improvement the multimedia services efficiency were this work motivation.  
For the 5G V2X research and development success, experiments are crucial for the system evaluation and the real implementation. Huge investments are being made by academia, industry, manufacturers and governments, around the world, to the first simulations and tests of the infrastructure that will be base of the future Internet, including IoT and IoV.  
This paper presented a 5G V2X ecosystem and evaluated scenarios with the eMBB use case, and V2V communications. Internet-based video services were simulated through the ecosystem with the goal to investigate it. The provision of IoV application (entertainment on board services delivery) through an SDIoV architecture has been evaluated. It was simulated through the ns-3 simulator, that is indicated as the best choice for complex scenarios and cellular systems. It was adopted in this work. The presented results show that the proposal can improve the IoV communications requirements under high-mobility (120 km/h vehicles in a rural environment) and high-density conditions (urban scenarios with good performance results).  
The future will have everything connected, integrated and a fully technology convergence is expected with the 5G evolution. Previous works have used MATLAB to evaluate the radio network in 5G vehicular architectures. The present work analyzes the results using ns-3, making this study one of the firsts with practical evaluation of end-to-end 5G integrated with VANETs obtained by ns-3 and compared with the MATLAB's ones. In this way, simulations were conducted showing as result the satisfactory performance of the 5G scenarios evaluated. The IoV services efficiency in 5G V2X networks can be reached with technologies integration. Scientific efforts are present world around to find appropriated solutions such as the SDIoV architecture that comes as a light for future directions.  
With the 5G networks implantation until 2020, studies and researches about its architecture, implementation and management are urgent. The 5G V2X ecosystem was conceived as an open architecture project, enabling the integration of various technologies, enhancement and extension of new protocols. The incorporation of elements into the proposed ecosystem structure, for example SDN, V2X and MEC servers, aims to allow the creation of new mechanisms for improved network services. Evaluations of other types of services can be carried out.  
In future works, V2V, V2I, and V2P simulations will be investigated using the developed ecosystem, assessing the situational information messages exchange (beacon) by the probability of situational awareness blackouts in the vehicular network. A new HAS algorithm can be created and the evaluation of other traffic models and measurements in real environments can be done.
