We analyze, design, and prototype Next-G networks that power future connected applications. Our work bridges rigorous theory with real-world implementation, creating innovative networking solutions that meet the demands of mission-critical applications.

Networks for Mission-Critical Applications: Theory Focus

Design of network control (e.g., routing and scheduling) algorithms with performance guarantees (in terms of throughput, latency, and/or information freshness) for wireless networks that support mission-critical applications. To develop such algorithms, we model the networked application and its objective function, use rigorous theory to develop algorithms, and derive bounds on their performance.

Selected Results:
– Estimation-based algorithm at IEEE INFOCOM 2025
– Learning algorithm at WiOpt 2021 (video)
– Theory-driven algorithms at IFIP WiOpt 2025, ACM MobiHoc 2019 (Best Paper Award Finalist) and IEEE INFOCOM 2018 (Best Paper Award)

Networks for Mission-Critical Applications: System Focus

Implementation, evaluation, and validation of our networking solutions using servers, FPGA-enabled Software-Defined Radios (SDRs), Multi-Drone Systems, Raspberry Pis, RF Integrated Circuits (RFICs), and Millimeter-Wave (mmWave) radars.

Selected Results:
– Networking solutions using 5G cellular (ongoing)
– Drone network at IEEE INFOCOM 2023
(flight test video and article from MIT News)
– Contention-free SDR network at IEEE ICCCN 2021 (experiment)
– Contention-based WiFi-like network at IEEE INFOCOM 2021  (experiment)

AI Embodied Radios

Design and implementation of AI-driven network control algorithms for fair, efficient, and adaptive resource allocation in dynamic wireless networks.

Selected Results:
– Dynamic routing in mmWave networks subject to weather-induced attenuation in ACM SIGMETRCS 2023.
– Adaptive selection of time-frequency blocks (see figure) in the presence of jammers and in ad-hoc wireless networks . Reinforcement learning (RL) was used in IFIP WiOpt 2025 (Best Paper Award).  Spiking Neural Networks are being used in NeurIPS’25 AI4NextG.
– Implementation of the RL-base algorithm in resource-constrained SDRs (ongoing).

Algorithms for Advanced Wireless Systems

Advanced wireless technology such as millimeter-wave (mmWave) and full-duplex will enhance beyond-5G networks. However, as wireless systems evolve and become more capable, they can also become more complex, requiring advanced algorithm solutions to control these systems in dynamic environments.

Selected Results:
– Adaptive control of Full-Duplex RF Integrated Circuits (RFICs) at GRCon 2024, IEEE RFIC 2023, and IEEE ISSCC 2021 (presentation)
– Dynamic spectrum access at TPRC 2025, IFIP WiOpt 2024 (Best Student Paper Award), TPRC 2024, and IEEE WCNC 2023
– AI-driven algorithm for opportunistic weather sensing using mmWave radars (ongoing)
