Prediction-based handover between VLC and IEEE 802.11p for vehicular environment

Participants : Mohammad Abualhoul, Fawzi Nashashibi.

Despite years of development and deployment, the standardized IEEE 802.11p communication for vehicular networks can be pushed toward insatiable performance demands for wireless network data access, with a remarkable increase of both latency and channel congestion levels when subjected to scenarios with a very high vehicle density.

In specific hard safety applications such as convoys, IEEE 802.11p could seriously fail to meet the fundamental vehicular safety requirements. On the other hand, the advent of LED technologies has opened up the possibility of leveraging the more robust Visible Light Communication (VLC) technology to assist IEEE 802.11p and provide seamless connectivity in dense vehicular scenarios.

In this particular research, we proposed and validated a Prediction-based Vertical handover (PVHO) between VLC and IEEE 802.11p meant to afford seamless switching and ensure the autonomous driving safety requirements [19].

Algorithm validation and platoon system performance were evaluated using a specially implemented IEEE 802.11p-VLC module in the NS3 Network Simulator. The simulation results showed a speed-based dynamic redundancy before and after VLC interruptions with seamless switching. Moreover, the deployment of VLC for platoon intra-communication can achieve a 10-25% PDR gain in high-density vehicular scenarios, where the work was published in the IEEE International Conference on Intelligent Transportation Systems 2018.
