A Novel IRS-relay Network for ITS with Nakagami-m Fading Channels
The Department of Electronics and Communication Engineering is proud to announce the publication of a research paper by Dr Sunil Chinnadurai, Assistant Professor and Research scholar Shaik Rajak titled “Novel Energy Efficient IRS-relay Network for ITS with Nakagami-m Fading Channels” in the Q1 journal ICT Express, having an Impact Factor of 5.4. The paper focused on developing an energy-efficient network for ITS that utilises Nakagami-m fading channels to improve communication reliability and efficiency.
In this work, the research duo introduced a cooperative system involving relay technology and an IRS (Intelligent Reflective Surface) with passive elements. Evaluating energy efficiency and achievable rates, they found that the cooperative relay-IRS system outperformed individual relay and IRS setups. The study also compared multi-IRS setups, highlighting their effectiveness in reducing power consumption and deployment costs for improved ITS development.
Abstract
The research paper investigates the performance of energy efficiency (EE) for Intelligent Transportation Systems (ITS) using a cooperative IRS-relay network. The proposed cooperative IRS-relay-aided ITS network integrates an IRS block with a number of passive reflective elements to improve EE. The research analyses the ITS in terms of EE and achievable rate under Nakagami-m fading channel conditions. The research aims to reduce power consumption over long distances and operate the system faster and safer.
Practical implementation/ social implications of the research
The proposed cooperative IRS-relay network for Intelligent Transportation Systems (ITS) has practical implications for improving energy efficiency and achieving higher data rates in ITS networks. Integrating an IRS block with passive reflective elements in the relay model enhances the coverage area and reduces power consumption in ITS. The research highlights the significance of cooperative IRS-relay and multi-IRS-aided networks in the development of ITS, which can contribute to safer and faster transportation.
Dr Chinnadurai and Mr Rajak Future will continue to work on their research focusing on optimizing the design of the cooperative IRS-relay network for ITS to improve energy efficiency and achievable data rates further in real-world scenarios.

Physics Duo Publish in Prestigious Journal
Dr Soumyajyoti Biswas, Assistant Professor in the Department of Physics, along with his Doctoral Scholar, Mr Soumyaditya Das, have presented groundbreaking findings through their research work titled “Critical Scaling through Gini Index”. The research paper was featured in the prestigious Physical Review Letters, which has an impact factor of 9.161.
Abstract
In the systems showing critical behaviour, various response functions have a singularity at the critical point. Therefore, as the driving field is tuned toward its critical value, the response functions change drastically, typically diverging with universal critical exponents. In this Letter, we quantify the inequality of response functions with measures traditionally used in economics, namely by constructing a Lorenz curve and calculating the corresponding Gini index. The scaling of such a response function, when written in terms of the Gini index, shows singularity at a point that is at least as universal as the corresponding critical exponent. The critical scaling, therefore, becomes a single parameter fit, which is a considerable simplification from the usual form where the critical point and critical exponents are independent. We also show that another measure of inequality, the Kolkata index, crosses the Gini index at a point just prior to the critical point. Therefore, monitoring these two inequality indices for a system where the critical point is not known can produce a precursory signal for imminent criticality. This could be useful in many systems, including condensed matter, bio- and geophysics to atmospheric physics. The generality and numerical validity of the calculations are shown with the Monte Carlo simulations of the two-dimensional Ising model, site percolation on the square lattice, and the fibre bundle model of fracture.
Fig.1: Shows the crossing point of the Gini index and the Kolkata index prior to critical point for three different models (from left Ising model in 2d, site percolation in 2d and fiber bundle model of fracture) form both side of critical point.
Collaborations and Future Plans
This work essentially builds a framework for indicating imminent critical points for any system. Therefore, in situations where such knowledge is vital, for example, in the fracture of solids, the method is going to be highly useful in forecasting the failure point. We are in the process of working with our collaborators at the University of Barcelona to experimentally verifying our methods for the compressive failure of porous samples. This is a significant first step towards opening new pathways in forecasting fracture points in disordered materials that could have an impact on laboratory-scale fractures to large constructions and eventually to earthquakes.
We wish the teacher-student duo many more fulfilling and enriching research endeavours in future!

Utilising Social Media Platforms for Crisis Management
Dr Vimal Babu, Associate Professor and Mr Selvakumar R, Research Scholar from the Department of Management, Paari School of Business has published a fascinating book chapter titled “Crisis Management and Social Media Platforms: A Review and Future Research Agenda” in the book Social Capital in the Age of Online Networking: Genesis, Manifestations, and Implications examining their perspectives on the ever-changing digital ecosystem and its repercussions.
In this chapter, we research duo has made a concerted effort to advance the understanding of crisis management using social media platforms (Social networking sites). Crisis management encompasses a broader spectrum of crisis leadership, and utilising social media platforms (SMPs) for crisis management (CM) has become the modern approach to handling crisis events. Recognising the importance of exploring and advancing crisis leadership concepts to enhance the existing body of knowledge, his work is the first to employ a bibliometric approach to investigate this area, contributing to the nascent literature on the subject. The unique insights garnered from this analysis are expected to provide valuable guidance to researchers and scholars interested in this emerging field.
The book “Social Capital in the Age of Online Networking” digs into the fascinating growth of relationships and connections in the virtual sphere in a digital era when clicks matter as much as handshakes. This edited volume reveals the pattern of our modern networked society, linking theoretical ideas and real-world implementations. The book’s objective is to provide a comprehensive understanding of the current and prospective state of theory and applications of this phenomenon, and it will benefit researchers, government and private research institutions, business corporations, and students in various fields such as business, economics, information technology, psychology, medicine, and humanities.
