Research

We at NWSL conduct research studies on the cutting-edge networking technologies supported by our very kind funding agencies such as National Science Foundation (NSF), National Institute of Standard and Technology (NIST), Defence Advanced Research Projects Agency (DARPA), NASA, AT&T, and many more. NWSLians study both theoretical and experimental aspects of networked systems. NWSL always supports and hosts inter-disciplinary research activities. Our ongoing collaborations with experts from economics, management, math, policy making, and physics is an example. Following are some of the key projects, we are involved in:

  • Modeling and Development of Resilient Communication for First Responders in Disaster Management (with UC Riverside, UIC, and Rutgers)
  • US Ignite: Rapid and Resilient Critical Data Sourcing for Public Safety and Emergency Response (with VCU): This project enhances the current systems by integrating a cloud-based rapid processing of collected data and augmenting the system by device-to-device (D2D) communications and network slicing. The project's integrated research and education plan investigates (i) large-scale critical data collection via a mobile app and management process to be used in the investigation of an emergency incident, (ii) near-real-time processing of the gathered heterogeneous data in a cloud computing environment for critical information extraction such as faces of people in the videos and photos, (iii) adoption of D2D-based communication as a complementary component to improve system resilience in case of congestion's and failures in network infrastructure, and (iv) utilization of Global Environment for Network Innovations (GENI) network slices as dedicated bandwidth for time-sensitive communication in emergency response as well as to enhance wide area resilience of the system. The project paves the way towards emergency preparedness which is a national priority and supports progress toward smart and connected communities. The anticipated enhancements expedite the response to emergency cases, save people's lives and reduce public safety operation costs.
  • Multi-Element Illuminication for Mobile Free-Space-Optical Networks (with FIU, NCSU): This project is developing a framework to design, optimize and test illumination-communication technologies considering needs and requirements for both functionalities. To attain mobile illuminication with high spatial reuse and throughput, and uniformly high illuminance; the project designs (i) multi-element illuminication modules which uses spherical structures for spatial reuse and uniform illumination, (ii) adaptive intensity control for energy saving and chromaticity control over red-green-blue LEDs, (iii) transceivers with varying field-of-view and divergence angle, (iv) automatic realignment protocols using electronic steering and focusing for mobility, (v) cognitive algorithms for transceiver selection, and (vi) optical wireless localization with high accuracy. This project is supported by National Science Foundation awards CNS-1422354 and CNS-1422062.
  • Pervasive Spectrum Sharing for Public Safety Communications (with NCSU and VTech): The overarching scientific merit of this research is to initiate the much-needed leap towards a more open, highly participatory, and pervasive sharing of the wireless spectrum for PSC. This project offers an array of spectrum sharing innovations: 1) new economic approaches and PSC mechanisms that provide incentives for government agencies, providers, and end-users, to effectively subsidize the scarce radio spectrum and facilitate novel public safety and spectrum allocation policies; 2) a foundational framework that tightly integrates tools from game theory and auction theory for enabling a dynamic operation of co-existing spectrum sharing markets with multi-hop capabilities; 3) novel realistic models for characterizing wireless channels, traffic, topology, user behavior, and mobility in PSC; and 4) effective and accelerated transition of theoretical results to practice via a new PSC testbed for extensive validation and close collaboration with several major industry partners and local public safety agencies. In a nutshell, the project provides a new generation of PSC systems and protocols that expedite the response to disasters, save lives, and reduce economic costs.
  • OMEGA: Online Management, Experimentation, and GAme of Large-Scale Networks: The project develops tools for automated management of a running network by framing heuristic optimization, empirical learning, experimental design, and network management with a “game” interface. The project will develop an online management and experimentation system for large-scale networks in a game-like environment for trainee administrators to play with and explore what-if scenarios, without having to risk the network operation. The project will also develop algorithms for empirical characterization of network dynamics, and tools for quick and close-to-optimal configuration of numerous network parameters in response to failures or customer traffic trends. Such a framework will automate the process of configuring a large-scale network, and thus reduce the dependency of ISPs to human network operators.The project integrates behavioral scientific concepts into the practice of operational network management. The automated management using online optimization may establish a foundation for managing multi-owner systems, e.g., power grid, transportation, and water infrastructure networks. The project’s heuristic optimization and experiment design methods, as well as the game-based approach to operator training, are applicable to training in safety and mission critical industries where mistakes of ill-trained administrators are intolerable, e.g., airline pilot and nuclear reactor administrator training.
