With its potential to mitigate traffic congestion and reduce road accidents, this innovation marks a significant leap forward.

The remarkable feature of this system is its ability to gauge the stress level of a driver by analyzing the driving patterns, say IIT Jodhpur researchers.

It can contribute to road safety by enabling secure and real-time communication between vehicles, allowing them to share information about road conditions, accidents, and traffic jams, say IIT Jodhpur researchers.

This information can be crucial for enhancing driver awareness and avoiding collisions.

NoMAS can also assist in improving road safety by facilitating the exchange of data on road conditions among vehicles.

This information can help drivers make informed decisions and avoid road hazards, say IIT Jodhpur researchers.

Team of IIT Jodhpur researchers

The team of IIT Jodhpur researchers include Dr. Debasis Das along with Mr. Jayant Vyas, Research Scholar, VANET Lab, Department of CSE, IIT Jodhpur, Ms. Bhumika, Research Scholar, VANET Lab, Department of CSE, IIT Jodhpur, and Prof. Santanu Chaudhury, Director, IIT Jodhpur.

The paper was published in Expert Systems with Applications (DOI: https://doi.org/10.1016/j.eswa.2023.119951). This is collaborative research with Jodhpur City Knowledge and Innovation Foundation (JCKIF), IIT Jodhpur.

The data collected and shared through the IoV network can also be analyzed to identify accident-prone areas, patterns of risky behavior, or road conditions that require improvement.

Authorities can then take proactive measures to address these issues. NoMAS security measures can also help protect vehicles from theft and unauthorized use.

Significant reduction

The proposed NoMAS MAC-based authentication scheme addresses key disclosure vulnerabilities and data leakage concerns in IoV networks.

NoMAS significantly reduces computational and communication overhead compared to existing schemes, without compromising on performance, as verified through formal security proofs using different tools.

This encryption not only ensures data confidentiality but also enhances performance significantly, reducing workload by up to 99.60% and cutting communication needs by approximately 81% compared to existing methods, say IIT Jodhpur researchers.

Easily Work

NoMAS can easily work with different types of vehicles in India, with the help of an On-board Unit (OBU), through this, they are able to communicate and create the IoV network.

In IoV, communication between vehicles and other IoV components can be performed using Dedicated Short-Range Communication (DSRC) protocol and Wireless Access in Vehicular Environment (WAVE) protocol.

Publishing

The research was published in IEEE Transactions on Intelligent Transportation Systems (DOI: 0.1109/TITS.2023.3242291) by Dr. Debasis Das, Associate Professor, and Ms. Himani Sikarwar, Ph.D. Student from the Department of Computer Science & Engineering, IIT Jodhpur.

More to it

While NoMAS plays a vital role in improving communication and sharing information among vehicles to help mitigate accidents, it’s crucial to understand that it isn’t a standalone solution for ensuring road safety in India.

The overall safety scenario relies on various factors like road infrastructure, traffic management, driver conduct, law enforcement, and vehicle safety features, say IIT Jodhpur researchers.

Aligning

Aligning with the same research, the IIT Jodhpur researchers have also developed a Federated learning-based driver recommendation for the next-generation transportation system.

Driving a vehicle under stress poses a danger not only to the driver but also to others on the road. There are many factors which put drivers under stress.

In this work we are concerned about driving-induced stress. This system gathers vehicle telematics data to identify different driving types and stress levels.

Once the system detects that a person is driving under stress, it can be addressed through various interventions, including taking breaks between consecutive rides, displaying alert messages, and imposing penalties for stressed driving, say IIT Jodhpur researchers.

Development

IIT Jodhpur researchers have developed a testbed called DD-Monitor (Driver’s driving monitor) which is able to collect real-time driving data and identify stressed and abnormal driving behaviour.

A run of DD-Monitor is already conducted on the roads of Jodhpur City which was successful.

The uniqueness of DD-Monitor is that it is useful for every individual. Parents can use this for monitoring their children.

Car rental companies can collect the rent based on how vehicles were driven, say IIT Jodhpur researchers.

Importance

Talking about the importance of both these research to reduce the occurrence of accidents on Indian Road, Dr. Debasis Das, Associate Professor, Department of Computer Science & Engineering, IIT Jodhpur, said they are excited to introduce the NoMAS (MAC-based authentication scheme) as a groundbreaking solution to enhance the security and efficiency of the Internet of Vehicles.

With NoMAS, we have strived to address critical challenges in data protection, communication overhead, and security vulnerabilities, he said.

Also, Our Federated learning-based driver recommendation for the next-generation transportation system helps detect driver stress and do the behavioural analysis.

These technologies will reduce pollution, traffic congestion and will also reduce road accidents, he said.
