NIT Rourkela AI Model

National Institute of Technology (NIT) Rourkela, researchers have received a patent for a model that aims to improve how vehicles communicate with each other in future. The patent, titled “Adaptive Contention Window Optimisation in VANETs using Multi-Agent Deep Reinforcement Learning for Enhanced Performance Model”, has been filed by Dr. Arun Kumar, Assistant Professor; Prof. Bibhudatta Sahoo, Professor, and Dr. Lopamudra Hota, Research Graduate, Department of Computer Science & Engineering, NIT Rourkela. Their work focuses on addressing a challenge in vehicular communication systems, known as Vehicular Ad-Hoc Networks, or VANETs.

The concept behind VANETs is that vehicles which are in proximity to each other will in future be able to communicate directly to each other. Consider a car warning other vehicles about precipitous braking or a sudden obstacle on the road. Such communication aids driving, automated traffic systems, and even provides assistance to emergency services. However, when multiple vehicles are contemporaneously sending out messages, the system is bound to face vehicle overcrowding. This congestion leads to delays or lost messages, which directly compromises the viable functionality of such systems.

Researchers at NIT Rourkela have suggested a solution that involves the use of artificial intelligence. Their model utilises a system known as multi-agent deep reinforcement learning. In layman's terms, it enables each vehicle to stagger the time of its messages depending on the actions of other vehicles. Instead of communications competing, the vehicles system learns to sequence and give priority to messages that are time sensitive.

The developed model ensures that even in busy conditions, the right message reaches at the right time, which can support safer mobility. This approach represents a step toward future transportation systems where vehicles can coordinate in real time.

Prof. Bibhudatta Sahoo, said. “The patent represents a practical step towards preparing India's road system for vehicle-to-vehicle communication. By addressing potential congestion in VANETs and providing a model for adoptive, coordinated communication, the findings lays the ground work for safer and a more efficient traffic management. We invite researchers across  institutions to join our efforts in making future autonomous vehicles and collaborate with our research lab at NIT Rourkela.”
