RUMORS
RUMORS (Resilience Utilizing Mirrors for Operation of Radio Systems):: Proposed an architecture for using the concept of Digital Twins for managing spectrum access in a distributed and dynamic infrastructure. RUMORS will mirror the real-world spectrum entities (radio, non-radio, and environment) onto virtual worlds, allowing systems to observe, structure, learn, and reconfigure the attributes of real-world devices to improve resiliency.
SPREADING
SPREADING (Security, Privacy, and Resilience Enabled Adaptive Design for Innovating Next Generation) Spectrum: Identified and evaluated existing approaches, new technologies, and methods, for spectrum stakeholders to incorporate adaptive and reconfigurable design while maintaining resiliency. Proposed frameworks that are sufficiently adaptive, trustworthy, and resilient to predict and/or manage cyber risks proactively and reactively.
Spectrum Rights
Understanding and evaluating the current regime of spectrum property rights and proposed a use rights model that leverages the adaptive and reconfigurable nature of wireless spectrum systems.
IRS aided THz
Intelligent reflective surfaces (IRS) aided THz communication: Proposed approaches to improve connectivity in the THz using distributed IRS in indoor and outdoor environments. Used reinforcement learning strategies to reduce outages induced by small-scale mobility and blockage in MATLAB.
MOTH
Indoor Mobility Management and Efficient Deployment in the THz: To analyze and identify challenges and solutions in THz communication. Proposed solutions using machine learning strategies (such, supervised and reinforcement learning) to predict small-scale mobility and improve antenna beamforming, eventually reducing outage and improving user coverage, in MATLAB/Python.
Enhanced ID
Improving Spectrum Efficiency in Heterogeneous Networks Using Granular Identification: Proposed an enhanced identification structure that monitors the physical and logical parameters associated with a device/antenna, to improve efficiency, enforcement and etiquette management.
Spectrum Observatory
Observing the RF Spectrum from WiNCom Spectrum Observatory: Objective was to develop a deep understanding of RF spectrum utilization in Chicago. Spectrum occupancy data was collected using Tektronix units from multiple sites and analyzed on MATLAB.
EARS
Enhancing Access to Radio Spectrum (EARS): To analyze and identify coexistence strategies for LTE and Radar Altimeter in 4.2-4.4 GHz band. Spectrum occupancy, ADS-B, and LTE antenna placement data in the Chicago area was used to simulate and propose coexistence models in MATLAB.
Capacity Modeling VoLTE
To build a tool in Python for Capacity Modeling followed by Traffic Migration for VoLTE. Identifying the components interfaces, protocols and messages that make up the EPC and the IMS cores. Analyze the SIP and Diameter PCAPS to get the Call Flows using Wireshark. Prepare a Troubleshooting document of VoLTE for NOC (Network Operations Center).
Vertical Soft Handoff
Evaluated the effective resource allocation for base-station and access-point to enable seamless vertical soft handoff (VHO). The simulation was done in C, where the objective was to propose a greedy algorithm for user to choose a connection Cellular or Wi-Fi or combined, such that the coverage of the network can be increased.
Secure On-Demand Routing in MANET
To develop a light-weight, energy efficient and secure on-demand routing protocol for MANETs. The models were simulated in C, where the ad-hoc nodes used fidelity, battery power and neighbor recommendation to make on-demand routing decisions.
