Researchers at the National Institute of Technology (NIT) Rourkela have been granted a patent for an innovative model designed to drastically improve the reliability of future vehicle-to-vehicle communication networks. The patented technology addresses the critical challenge of message congestion in high-traffic scenarios, paving the way for safer, smarter road systems in India.

The patent, titled ‘Adaptive Contention Window Optimisation in VANETs using Multi-Agent Deep Reinforcement Learning for Enhanced Performance Model,’ was filed by Dr. Arun Kumar, Assistant Professor; Prof. Bibhudatta Sahoo, Professor and Dr. Lopamudra Hota, Research Graduate, all from the Department of Computer Science & Engineering at NIT Rourkela.

Their work focuses on Vehicular Ad-Hoc Networks (VANETs) – the foundational concept that enables vehicles in close proximity to communicate directly with one another. VANETs are essential for future functionalities like warning drivers about sudden obstacles or precipitous braking, aiding automated traffic control and assisting emergency services.

However, a core issue in VANETs is overcrowding. When multiple vehicles transmit messages simultaneously, the congestion leads to delays or lost messages, which severely compromises the system's ability to function safely.

The NIT Rourkela solution tackles this problem using artificial intelligence (AI). Their model employs multi-agent deep reinforcement learning to enable each vehicle to intelligently stagger the timing of its messages based on the real-time actions of other vehicles in the network. Instead of communications competing and colliding, the system learns to sequence and prioritise time-sensitive alerts, such as emergency warnings. This adaptive adjustment significantly reduces transmission delays, ensuring critical alerts are reliably delivered.

Dr. Arun Kumar highlighted the profound safety implications of their research, referencing the severe toll of road accidents in the country. “In 2023, India reported around 480,000 road accidents and around 172,000 deaths, many of which could be prevented using modern technologies. Our work is a step towards building safer roads and smarter cities. We envision a near future where autonomous vehicles become a reality in India, and this patent is a small step in that direction, driving the spirit of Innovate in India and Make in India,” Dr. Kumar said.

The developed model ensures that even under busy conditions, the right message reaches the right recipient at the right time, a crucial requirement for future transportation systems where vehicles must coordinate in real-time.

The enhanced communication model has broad applications across future mobility. Current VANETs use cases include:

• Electronic brake lights: Notifying drivers of braking scenarios not yet in their line of sight.
• Platooning: Enabling a series of cars to closely follow a lead vehicle using distributed acceleration and steering control data.
• Enhanced Navigation: Providing instantaneous, accurate information on current road traffic conditions.
• Emergency Response: Rapid broadcast of crucial information to vehicles in an area affected by an incident.
• Electronic Toll Collection: Providing remote access to real-time data for automated toll systems.

Prof. Bibhudatta Sahoo emphasised the practical impact of the work on national infrastructure. “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 lay the groundwork 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,” said Prof Sahoo.

Honda R&D, a subsidiary of Honda Motor Co., has developed underlying technology for a magnetic coupling wireless power transfer road system in partnership with Taisei Corporation and Taisei Rotec Corporation.

The system enables wireless in-motion charging for electric vehicles, including passenger cars and heavy commercial fleets. The partners plan to initiate demonstration testing on public roads starting in FY2027.

The technology integrates high-power-density receiver and transmitter units from Honda with a high-response direct current power supply system from Taisei and road-embedding construction techniques from Taisei Rotec. By supplying power to electric vehicles while in motion, dynamic wireless power transfer reduces the need for stationary charging infrastructure. The initial commercial focus targets logistics and transport operations, where continuous operation offers economic benefits.

The ground assembly embedded in the roadway combines the inverter and coil into a single unit designed to connect via direct current distribution. This design reduces component counts, simplifies wiring and supports installation into existing road surfaces through standard milling methods. The road pavement structures are engineered to withstand continuous traffic loads from vehicles weighing up to 20 tonnes (20,000kg).

Testing conducted at Taisei Group’s T-FIELD facility in Satte verified system stability and structural durability. Starting in late 2026, the companies will build a test roadway at T-FIELD Tamura to evaluate long-term durability under one million wheel-load cycles, measure power transfer efficiency at outputs up to 150 kW and analyse electromagnetic shielding.

The partnership will also join the Tateyama Expressway demonstration project managed by East Nippon Expressway Company starting in 2027.
