With a strong telecommunications background, I work on a range of topics/areas in wireless and networking domains. My research broadly focuses on design, optimization, and performance evaluation of wireless networks. With an emphasis on protocol and architectural aspects, my work spans a number of networking technologies. I enjoy working on fundamental/theoretical as well as application-oriented problems. I particularly like problems of cross-disciplinary nature where co-design and systems research techniques can be applied. I am also engaged in various innovation activities.
[current] This research revolves around enabling technologies and protocol stack optimizations for private (local) 5G networks targeting vertical industries. It also involves integration of local 5G with time-sensitive networking (TSN) and multi-access edge-computing (MEC) technologies.
[current] The objective of this research is to develop novel wireless solutions, providing high-performance connectivity (in terms of latency, reliability, and scalability), for meeting the requirements of industrial control applications. Prominent wireless solutions (IP owned by Toshiba) developed as part of this activity include GALLOP, ENCLOSE, and HAR2D-Fi.
[current] I am engaged in 6G (beyond 5G) networks research with emphasis on non-terrestrial networks (NTNs), joint radar-communication techniques, and new AI-driven control paradigms for industrial as well as consumer applications.
[current] This research focuses on challenges lying at the intersection of robotics and networking domains. I am involved in development of novel solutions for cooperative mobile robotic systems targeting logistics and warehousing industry.
[past] I started working on Tactile Internet during my post-doc at KCL when it was still an emerging area of research. I contributed toward characterizing system-level architectural and technology requirements, and radio resource allocation techniques for haptic communications over 5G networks. I have also contributed to the IEEE P1918.1 standard on Tactile Internet.
[past] This research focused on design and evaluation of wireless networks with nodes equipped with full-duplex radios. In mobile/cellular context, performance aspects of HetNets with full-duplex small cells were investigated. For non-cellular technologies, novel MAC layer and cross-layer protocols were developed to maximize system-level performance gains of full-duplex operation.
[past] As one of the main topics of my PhD research, I developed novel MAC and routing protocols for M2M networks, underpinned by cognitive radio capabilities, with a particular focus on smart grid applications.
[past] I worked on molecular communication (for nanonetworks) during my PhD. My work focused on performance evaluation of diffusion-based molecular communication as well as design of (simple) protocols for multi-hop communication.
Some of my other areas of research include IEEE 802.11 WLANs (ongoing), distributed ledger technologies (ongoing), stochastic geometry (past), and wireless sensor networks (past).
