Recently, the National Science Foundation awarded Professor Yingying Chen with a grant to research, "Securing Spectrum Usage in Future Radio Systems."

Since the future wireless devices will be highly-programmable with the exposure of the protocol stacks to the public, adversaries can easily purchase low-cost wireless devices to launch a variety of attacks with little effort. There is an urgent need to regulate and monitor future radio operations to ensure the spectrum is properly used. This project aims to design efficient mechanisms and develop effective frameworks to detect anomalous spectrum activities and secure spectrum usage in future radio systems.

This project represents a significant contribution to future radio systems because it departs from traditional cryptographic-based security solutions, and utilizes properties that are unique to wireless communications to secure spectrum usage. This work can provide a foundation in exploring various properties related to wireless communications that can augment traditional security mechanisms.

The National Science Foundation (NSF) newly awarded Stevens Professor Yi Guo with a grant to research the "Control of Atomic-Scale Friction by Normal Surface Oscillation."

The goal of the NSF project is to develop control methodologies to reduce friction at the atomic-scale by surface vibration. Professor Guo plans to pursue a rigorous mathematical understanding of the effect of normal surface oscillation on friction, and to develop control methods to quantitatively adjust vibration parameters. She also plans to validate the analytic results through atomic force microscopy (AFM) experiments. To achieve the research goal, she will hire a graduate research assistant, and work closely with collaborators at Oak Ridge National Laboratory, who have extensive experience on atomic-scale friction and AFM.

Dr. Chandramouli has been awarded grant by the Office of Justice Programs of the Department of Justice for his Project titled "Cognitive radio protocols and platform for dynamic spectrum access in public safety bands."

Project Description

Recent studies (e.g., Project SAFECOM) have shown that radio spectrum is fragmented over space and time leading to inefficient use of radio resources. Dynamic spectrum access using cognitive radios allow users to dynamically share the available spectrum to maximize spectral efficiency. The project proposes to research and develop software defined radio based cognitive radio technologies that facilitates public safety radios to dynamically occupy and release spectrum whenever and wherever they are available in the public safety bands. Protocols for spectrum aggregation to create a broadband connection for supporting quality of service for voice and data applications will be developed. The proposed protocols will be implemented, tested and demonstrated in a software defined radio platform. Catastrophic loss of wireless links and graceful degradation will be emulated in the test bed to demonstrate the gains that can be achieved using the proposed technology.

Finally, this study will facilitate a better understanding of the pros and cons of FCC's spectrum policy reform.
