VDL: Reliable and Scalable Vehicle-to-Everything (V2X) Protocol Design for Intelligent Transportation

Reliable and scalable wireless transmissions for Vehicle-to-Everything (V2X) are technically challenging. Each vehicle, from driver-assisted to automated one, will generate a flood of information, up to thousands of times of that by a person. Vehicle density may change drastically over time and location. Emergency messages and real-time cooperative control messages have stringent delay constraints, while infotainment applications may tolerate a certain degree of latency. On a congested road, vehicles need to exchange information badly, only to find that services are not available due to scarcity of wireless spectrum. Considering the service requirements of heterogeneous V2X applications, service guarantee relies on an in-depth understanding of network performance and innovations in wireless resource management. In this talk, we compare the performance of vehicle-to-vehicle (V2V) beacon broadcasting using random access-based (IEEE 802.11p) and resource allocation-based (C-V2X) protocols and introduce several enhancement strategies to mitigate packet collisions, recover from transmission errors, and support two-user non-orthogonal transmissions. They can be become enabling tools toward reliable and scalable V2X for future intelligent transportation systems.

Reliable and Scalable Vehicle-to-Everything (V2X) Protocol Design for Intelligent Transportation

Reliable and scalable wireless transmissions for Vehicle-to-Everything (V2X) are technically challenging. Each vehicle, from driver-assisted to automated one, will generate a flood of information, up to thousands of times of that by a person. Vehicle density may change drastically over time and location. Emergency messages and real-time cooperative control messages have stringent delay constraints, while infotainment applications may tolerate a certain degree of latency. On a congested road, vehicles need to exchange information badly, only to find that services are not available due to scarcity of wireless spectrum. Considering the service requirements of heterogeneous V2X applications, service guarantee relies on an in-depth understanding of network performance and innovations in wireless resource management. In this talk, we compare the performance of vehicle-to-vehicle (V2V) beacon broadcasting using random access-based (IEEE 802.11p) and resource allocation-based (C-V2X) protocols and introduce several enhancement strategies to mitigate packet collisions, recover from transmission errors, and support two-user non-orthogonal transmissions. They can be become enabling tools toward reliable and scalable V2X for future intelligent transportation systems.
