Work Area: Indoor Positioning using Visible Light Communication

Brief: I work in the area of indoor visible light communication. In this work, we analyze the performance of an indoor VLC system in the presence of obstacles, both static (like, furniture) and dynamic (like a human). In order to improve the performance of an indoor VLC system, we optimize the VLC parameters like LED irradiance angle, receive field of view, power to the LEDs, which will result in better BER, uniform illumination, and saved power.

Name: Gurinder Singh

Work Area: Optical Communication and Wireless Communication

Brief: I work in area of vehicular-visible light communication (V-VLC). V-VLC can be envisioned as a complementary solution to the existing vehicular radio frequency (V-RF) technologies by utilizing deployed vehicle headlamp’s light emitting diode (LED) lights as transmitter and photodetector (PD) or camera as the receivers, thereby facilitating dual utility of light: illumination and communication. In particular, our proposed hybrid V-VLC/V-RF solution may serve as a preferred alternative for future intelligent transportation system (ITS) to meet ultra-high reliable and ultra-low latency communication for beyond 5G (B5G) vehicular networks.

Work Area: LiFi4IoT, advanced modulation schemes for VLC, and coexistence of heterogeneous users (LiFi and VLC)

Brief: I have worked on enhancing the performance of light communication in resource, power and hardware constrained systems such as low complex probabilistically shaped color shift keying (CSK) for IoT, constellation design and optimization for low-cost CSK, green communication-based coexistence schemes for heterogeneous users (LiFi users and LC enabled IoT devices) under a common LiFi AP. Recently, I have worked on enhancing coverage and illumination with the 3D deployment of VLC enabled UAV for mobile users.

Name: Rizwana Ahmad

Work Area: Hybrid LiFi-WiFi

Brief: My Ph.D. focused on improving the Light Fidelity (LiFi) physical layer and its coexistence with WiFi using advanced modulations such as Optical-OFDM, Optical-GFDM, CAP, DFT precoded OFDM for solving the problem of high peak-to-average-power ratio (PAPR) of optical-OFDM and machine learning-reinforcement learning (RL) based methods for ensuring optimum load balancing in heterogeneous LiFi WiFi network (HLWN). Specifically, the problem of load balancing in HLWN is a non-convex mixed integer non-linear programmable problem, therefore, we explored the RL to solve this issue. From our research, we discovered that RL based load balancing technique for HLWN can provide near-optimal performance at fairly low complexity.

Work Area: Physical and MAC layer of LiFi network, Coexistence of WiFi and LiFi Networks for indoor communication

Brief: In the LiFi network, the user requests the data from LiFi AP using an access technique based on Medium Access Control (MAC) protocol. The protocol decides the performance of the multi-user LiFi network based on the average data rate received by the users or average network throughput, the probability of getting the channel busy or free, the collision between the nodes, etc. Majorly, the design of effective MAC protocol decides above performance metrics.

In a hybrid LiFi WiFi network, LiFi provides a higher data rate and lower coverage whether WiFi provides a lower data rate with a higher coverage area in an indoor scenario. Therefore, the coexistence of LiFi and WiFi networks provides a high data rate and more coverage to the user in indoor communication. In addition, this is also mitigating the issue of a loaded WiFi network.

Work Area: Elastic Optical Networks in Multi-band Scenario

Brief: Multi-band optical transmission is becoming a cutting-edge area of research. This technology enhances the utility of already deployed standard Single-Mode Fibers (SMF) beyond the conventional C band (1530 - 1565 nm) by applying new amplification techniques and innovative mitigation strategies of several physical layer impairments. To overcome the expected capacity crunch, our objective is to utilize the additional spectrum, O, E, S, and L band of already deployed SMF fiber along with the conventional C band. This research will give an idea to the operator about the pros and cons of deploying a Multi-band fiber infrastructure according to the specific network's property.
