Prof. Suresh Subramaniam and his colleagues Profs. Guru Venkataramani and Omur Ozel received a $584K award from NSF for the project titled, "Expedient computing: A framework for energy-efficient and timely computing at the edge". The project period is Oct. 2022 - Sep. 2025. A summary of the project is given below:

Emerging and future cyber-physical system applications demand timely processing at the network edge of large volumes of fresh data from sensor nodes, which may have limited processing ability and energy budgets. The sheer variety of envisioned applications and their requirements call for new performance metrics and strategies for balancing freshness of information, timeliness and accuracy of results, and the energy consumed in producing those results. This project proposes and develops a new holistic framework called Expedient Computing, in which results are produced as quickly as needed, with as much precision/accuracy as needed, using information that is as fresh as needed. The specific research objectives of the project include: (i) characterizing fundamental tradeoffs in expedient computing, (ii) exploration of emerging hardware designs in edge servers for expedient computing, (iii) developing an integrated optimization framework for expedient computing, and (iv) demonstrating expedient computing principles. This cross-disciplinary project will draw upon expertise in hardware architecture, network optimization and performance analysis, algorithms, and fundamental limits.

Prof. Suresh Subramaniam received a $236K award from NSF for the project titled, "JUNO3: End-to-end network slicing and orchestration in future programmable converged wireless-optical networks". The project period is Sep. 2022 - Aug. 2025. The project is a collaboration with Prof. Shih-Chun Lin of North Carolina State University, Prof. Hiroshi Hasegawa of Nagoya University, and Prof. Motoharu Matsuura of University of Electrocommunications, Tokyo. A summary of the project is given below:

Beyond 5G/6G and next-generation core networks promise a wide range of new applications and industrial verticals such as digital enterprise, Industry 4.0, and smart cities. Revolutionary technological breakthroughs in all domains, including access fronthaul, edge clouds, and core networks, are necessary to realize this unprecedented opportunity through timely end-to-end performance guarantees. Several challenges must be overcome in order to achieve this. The objective of this project is to meet these challenges and develop critical enablers to realize the full spectrum of beyond 5G/6G applications. The specific aims are to: (a) design resilient fronthaul architectures based on novel power-over-fiber technology to provide wireless access survivability; (b) Design automatic edge cloud management and service chain deployment by leveraging machine learning techniques and Markov decision processes; (c) design multi-petabit optical core networks and efficient access-edge-core orchestration and slicing for stringent service-level agreements; and (d) prototype a wireless-optical network testbed and evaluate end-to-end harmonization performance.

Dr. Subramaniam was interviewed and quoted in a Washington Post article published on June 29, 2021, about unusual phone calls from the collapsed condo complex in Florida. https://www.washingtonpost.com/nation/2021/06/29/florida-condo-collapse-phone-calls/
