Case Studies and Real-World Applications of SDN for VANETs
Several pilot projects and research studies have demonstrated the efficacy of SDN in managing VANETs. By injecting programmability and centralized control into the dynamic web of connected cars, SDN paves the way for smarter, safer, and more efficient roads. Let’s have a look into some real-world case studies showcasing the transformative potential of this technology:
- City of Santander, Spain: the city of Santander in Spain deployed an SDN-enabled VANET for Real-time traffic routing, accident warnings to optimize public transportation management which led to positive result showing a 20% traffic flow improvement, a 15% decrease in accidents, and a 30% surge in public transportation ridership.
- Seoul Metropolitan Expressway, South Korea: Seoul was able to eased congestion and enhanced safety on its Metropolitan Expressway using SDN-controlled VANETs it Prioritized trucks, providing real-time lane guidance and optimized toll collection which resulted into a drastic 25% reduction in truck travel times, an 18% drop in accidents involving trucks, and a remarkable 99% toll collection efficiency, showcasing the effectiveness of smart transportation solutions.
SDN for Vehicular Ad-Hoc Networks (VANETs)
In recent years there is a rapid evolution in vehicular communication systems which has been a crucial point in the advancement of intelligent transportation systems (ITS) Among these Vehicular Ad-Hoc Networks (VANETs) have emerged as an important component facilitating vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication However, managing the dynamic nature of VANETs poses significant challenges inviting Software-Defined Networking (SDN) to arrive as a promising solution to enhance the performance and efficiency of VANETs.
