WiCom Research Group at IIT Indore is conducting fundamental and applied research to cater to the emerging needs of the next generation wireless communication systems. The research at WiCom leverages tools from statistics, random processes, convex optimization, signal processing, and a few simulation packages. The group has currently developed and analyzed various spectral‐efficient algorithms and spatial diversity schemes by exploiting the emerging wireless techniques like MIMO, cooperative communication, and cognitive radio. These theoretical developments and findings will help the design of future wireless systems that can accommodate the increasing data traffic demands over a limited spectrum. They have found useful applications in the deployment of wireless cellular, ad-hoc and sensor networks. The group has contributed to a significant number of publications in IEEE journals and conferences over the last couple of years. The research at WiCom is partially supported by the Department of Science & Technology (DST) under fast-track scheme for young scientists

Research Area: Performance Analysis of Two-Way
Relaying with MIMO and D2D Communications
Wireless communication is the fastest growing area of the Communications Engineering, as it employs such attributes which were beyond to the imagination of humanity. We have seen four different generations of wireless communication system till now, having certain boon features with some impairment. Now a day’s, various challenges pertaining to the throughput, reliability, and spectrum scarcity under wireless environment are emerging to enable future applications. Over the past few years, MIMO technology has been developed as a promising technology for achieving high data rate, spatial diversity, spectral efficiency, etc. However, combining such techniques with cooperative communication protocols can lead to a benevolent means for enhancing the performance of future generation of wireless systems. With this motivation, I am working at the WiCom group to explore the advantages of MIMO techniques in practical wireless relay systems, where channel impairments play a crucial role.
Research Area: Estimation and Optimization of Design Parameters in Diffusive Molecular Nanonetworks
Advancements in the field of nanotechnology require an efficient and reliable communication between nanomachines, especially for realization of applications such as targeted drug delivery, health and environment monitoring. The existing electromagnetic wireless communication may not be applicable at nanoscale due to issues such as antenna size, power consumption, computational complexity, and signal attenuation in fluidic environments. Molecular communication is a promising and attractive technique for nanoscale communications due to its biocompatibility (where chemical signals are used as information carriers). Currently, diffusion-based molecular communication (DMC) is the most simple and energy-efficient scheme for exchanging information among nanomachines. I am working towards the performance improvement of DMC system in realistic environments.
Research Area: Performance Analysis of Cognitive Relay Networks Using Spectral- and Energy-Efficient Schemes
In today’s world, we cannot imagine our life without information technology, and in the years to come, the demands and needs for this technology are expected to proliferate even more. Such proliferation put forth the challenges for researchers to design the systems with high performance specifically concerning high-speed, full coverage and spectral efficiency.
My research interest is in the area of physical layer security of wireless communications system. Physical layer security has recently become an emerging technique to complement and significantly improve the communication security of wireless networks. Physical layer security is fundamentally different approach where secrecy is achieved by exploiting the properties of physical layer of the system, such as noise, time-varying nature of fading channels and interference. Because of such unexpected nature of fading channels, security of wireless communication network has been the subject of exploration.

Research Area: Performance Analysis of Cognitive Hybrid Satellite-Terrestrial Networks for Futuristic Wireless Communications.
The explosion of mobile applications, wireless data traffic and their increasing integration in various aspects of everyday life have increased the need of deploying modern wireless telecommunication system, that can handle such exponentially increasing traffic. The radio spectrum scarcity, seamless data connectivity and wide coverage are the most important characteristics to consider while deploying modern wireless systems. In this context, hybrid satellite terrestrial systems have been envisioned to enhance the radio spectrum utilization by enabling spectrum sharing between the satellite and terrestrial systems.

Research Area: Performance Analysis of Next Generation Wireless Communication Systems
The global IP traffic in 2024 is expected to triple from 2020 levels, reaching around 600 exabytes (EB) per month. It is due to using a high definition (HD) real-time video streaming, ultra-fast data download and teleconferencing. The drastically increase in the network traffic on a radio link has required a high speed and high capacity transmission link technology with unlined connectivity. Bandwidth scarcity in the microwave region has led to the standardization of new unlicensed bands in the millimeter-wave (mm-wave) range, particularly around the 60 GHz frequency and terahertz frequency (THz) range. Due to the continuous growth of mobile devices and the rapid development of the Internet of things (IoT), the next wireless communication networks impose an explosive demand on low latency and massive connectivity over limited radio resources. Non-orthogonal multiple access (NOMA), which has shown the potential to improve spectral efficiency, balance user fairness, enlarge connections, and reduce access latency, has been envisioned as a promising technology for next-generation wireless communication. In contrast to the conventional orthogonal multiple access (OMA), NOMA simultaneously serves a multiple users with the same radio resource via superposition coding, where different users are distinguished with different power levels and the successive interference cancellation (SIC) is applied to cancel the multiuser interference.
I am working at the WiCom group to designing and modelling such systems. My research interest is in the area of next-generation wireless communication, Internet of things (IoT), NOMA technique, millimeter-wave, physical layer security, cognitive radio, cooperative relaying, and energy harvesting.
