🔬 Research Areas

Illustration of a Wi-Fi 7 multi-link device communicating over 2.4, 5, and 6 GHz links

NEXT-GENERATION WLAN

Wi-Fi 7 Multi-Link Networking

Analysis and design of IEEE 802.11 multi-link operation, including cross-link self-interference, fair channel access, and behavior under saturated traffic. The objective is predictable, standards-compatible performance across multiple links.

Representative work J1 J3

Illustration of coordinated Wi-Fi and Bluetooth Low Energy operation in a dual-stack device

HETEROGENEOUS WIRELESS

Bluetooth–Wi-Fi Coexistence and Cooperative Discovery

Cross-stack coordination between Wi-Fi and Bluetooth/BLE is used to reuse otherwise idle airtime and share scan information. These mechanisms improve throughput and reduce the time and energy cost of discovering nearby access points.

Representative work J5 C3

Illustration of an underlay IoT network adapting packet length around overlay wireless traffic

ENERGY-EFFICIENT IOT

Interference-Aware IoT Networking

Statistical modeling and parameter adaptation for low-power CSMA/CA networks operating beneath higher-power overlay traffic. Packet sizes are tuned to maximize bit-per-joule efficiency in shared unlicensed spectrum.

Representative work J4

Illustration of update and inference task scheduling between a physical twin and a cyber twin

REAL-TIME CYBER–PHYSICAL SYSTEMS

Digital Twin Scheduling and Synchronization

Joint scheduling of update and inference tasks, fairness across cyber twins, synchronization-error control, and optimization of update and inference timing for responsive digital twin services.
