Time Sensitive Networking (TSN) switch

• µTAS - Designed a P4-MicroC-based SmartNIC that offloaded Time-Aware Shaper and achieved 20µs latency between hosts across two switches.
• Implemented packet de-duplication algorithms that ensured 100% and 99.83% packet delivery for two and tweleve streams respectively across two links each with 10% loss.
• EdgeP4 - Embedding intelligence for pose correction and tremor suppression in P4-programmable edge switches, reducing control loop latency (<100µs) and network load (99% reduction) and demonstrating versatility in algorithm-switching for distinct tasks via P4's match-actions.

Acoustics Based Localization

• Developed an application to locate multiple wireless edge devices with embedded microphones by using audio signals from speakers.
• Simulated a few localization algorithms using MATLAB. Implemented KNN fingerprinting based localization of the receivers and achieved an accuracy of 98%.
• Novelty - Unlike the usual source localization, here, the receivers (mics) are localized when the locations of speakers are known.

Airplane IoT data analytics and management

• Developed machine learning algorithms to classify anomalies and take corrective actions using real-time data generated from sensors from a MATLAB/Simulink model of an aircraft environmental control system.
• Novelty - Developed an algorithm that does linear interpolation between non-consecutive data points from time series data to adaptively store data based on a cost function which balances storage space savings and error in reconstruction of data. Achieved 96% savings in storage space.

Video casting

• As 2.4 & 5 GHz Wi-Fi is congested in an aircraft cabin in which 400+ passengers cast media onto seat back displays in close proximity, using IEEE 802.11ad, 60GHz Wi-Fi (Wi-Gig) & 802.11ax (Wi-Fi 6E) was explored.
• MATLAB WLAN Toolbox was used to simulate the physical behavior of Wi-Fi transmissions in a dense environment.
• Novelty - Developed an algorithm that dynamically allocates different channels to 400 transmitters such that the packet error ratio is zero (PER = 0).
