Wireless @ VirginiaTech Student Sudeep Bhattarai Contributes in the Design and Deployment of the First Prototype ESC


Sudeep Bhattarai, a PhD student advised by Professor Jerry Park in the Department of Electrical and Computer Engineering, actively contributed in the design, development and deployment of the first prototype Environmental Sensing Capability (ESC) in San Francisco during his summer research at Google. This deployment is the first step towards enabling shared usage of 150 MHz of the radio spectrum in the 3.5 GHz band, also known as the Citizens Broadband Radio Service (CBRS) band.

The U.S. Federal Communications Commission (FCC) has recently opened the 3.5 GHz band for sharing between the Navy’s shipborne radars (incumbent users) and broadband communication systems (CBRS devices). A fundamental requirement for shared use of this band is that a dedicated network of sensors called ESCs must detect incumbent operations and alert the spectrum manager. The spectrum manager for the CBRS band is called the Spectrum Access System (SAS). SAS maintains orderly use of the band while protecting incumbents and coordinating spectrum use among CBRS devices. Upon receiving an alert from the ESC, the SAS reconfigures CBRS devices under its control to avoid harmful interference to the Navy radar.

Google, among others, has applied to the FCC to operate both a SAS and an ESC, and has been actively developing software and hardware capabilities to detect incumbent radars. The goal is to deploy a network of ESCs along the U.S. coastline and allow CBRS devices to operate in the coastal areas provided that they do not cause harmful interference to the incumbent users.

Papers from Dr. Jerry Park’s Group Featured in IEEE Communications Society (ComSoc) Best Readings in Cognitive Radio (CR)

 

Dr. ParkThe IEEE Communications Society (ComSoc) has selected two papers from Dr. Jerry Park’s ARIAS (Advanced Research in Information Assurance and Security) research group for inclusion in the ComSoc’s Best Readings in Cognitive Radio (CR) list. The first paper entitled “Defense against primary user emulation attacks in cognitive radio,” written by R. Chen, J. Park and J. H. Reed was originally published in January 2008 in the IEEE Journal on Selected Areas in Communications. This paper systematically shows that “primary user emulation” attacks can result in severe interference and significantly reduce spectrum utilization. To address the problem, the authors propose a transmitter verification scheme that is able to identify whether a signal is being transmitted from primary users or not by using an estimate of the transmitter’s location and the characteristics of the signal itself.

The second paper entitled “Toward secure distributed spectrum sensing in cognitive radio networks,” was coauthored by R. Chen, J. Park, Y. T. Hou, and J. H. Reed, and was originally published in April, 2008 in the IEEE Communications Magazine. This paper introduced pioneering work on mitigating security threats such as incumbent emulation and spectrum sensing data falsification threats in cognitive radio networks. The paper also described countermeasures for addressing those threats. The IEEE ComSoc’s Best Readings in Cognitive Radio (CR) list is a recommended reading list of books, articles and papers on Cognitive Radio Communications and Networking that are of interest to the IEEE ComSoc readership. IEEE ComSoc’s Best Readings in Cognitive Radio (CR) list is available here.

Jerry Park Awarded Major NSF Grant To Address Dynamic Exclusion Zones in Radio Spectrum

 

Dr. ParkThe Federal Communications Commission is opening up bands of spectrum that were previously restricted to a few priority users, including the military. Virginia Tech College of Engineering professor Jung-Min “Jerry” Park is leading a $730,000 National Science Foundation grant collaboration with William Lehr from the Massachusetts Institute of Technology, to find ways to make this transition as smooth as possible. The FCC’s plans to provide incumbent users with a wide, insulating boundary, often called an exclusion zone, separating them from new users. In this type of environment, incumbent users have first dibs on the spectrum, and the secondary users can access what’s left over. 

Park, of the Bradley Department of Electrical and Computer Engineering, and his collaborators intend to develop a new strategy supporting blueprints for flexible exclusion zones, or an adjustable boundary, that can respond dynamically to the incumbent protection requirements and the interference environment. In this way, incumbent users will still have safe, clear access to their frequencies, but secondary users will be able to make efficient use of the spectrum when it’s free. Read more

 

Jerry Park Elected to Serve on Executive Committee of the National Spectrum Consortium


Dr. ParkJerry Park, professor in the Department of Electrical and Computer Engineering, has been elected to a three-year term serving as an academia representative on the Executive Committee of the National Spectrum Consortium (NSC).

The NSC is a non-profit organization formed in 2014, whose mission is to improve collaboration between industry, government, and academia to advance research and development of technologies to better use the electromagnetic spectrum. The Executive Committee is the NSC leadership and governance body authorized to oversee the activities of the Consortium.

New wireless technologies and applications have skyrocketed the demand for spectrum, which is a finite natural resource. The ability to efficiently manage that resource is critical to the national economy and the military’s ability to secure wireless communications. The NSC has signed a $1.25 billion, five-year contract with the Office of the Deputy Assistant Secretary of Defense, Emerging Capabilities and Prototyping Office, to develop a research and development program designed to maximize utilization of the spectrum by broadening the commercial use of available spectrum while protecting the U.S. military’s access to select radio frequencies.

As an Executive Committee member of the NSC, Park will work with the other members of the committee to develop policy to govern the development of research and business opportunities that will meet the Consortium’s goal. Over $500 million dollars will be available to help Consortium members finance and advance the research and development, and transfer the resulting technology to the marketplace.

Jerry Park is the associate director for affiliate relations of Wireless @ Virginia Tech, a research group within the Bradley Department of Electrical and Computer Engineering, dedicated to the development of wireless technology, as well as the site director of the Broadband Wireless Access and Applications Center (BWAC), an NSF-funded Industry-University Cooperative Research Center (I-UCRC) whose primary mission is to advance research collaboration between researchers in academia and industry partners and promote the transfer of technology from universities to the industry.

Dr. Jerry Park Receives CISCO Grant

Dr. ParkJerry Park recently received a Cisco Faculty Research Award.  The title of the project is “Anonymity-Preserving Authentication for Large Networks”.   Cisco Research Awards are one-year awards structured as unrestricted gifts to universities to support the work of faculty members that are working on innovative solution approaches to challenging problems in networking,  programmable networks, and cybersecurity.

In many network applications, we need to be able to authenticate the data while, at the same time, protect the anonymity or privacy of the data source—in other words, anonymity-preserving authentication (APA) is needed.  Existing approaches for APA have limited utility in large networks due to their high computational complexity and/or high communication overhead.  Park and his team will investigate novel approaches for APA and study the performance and security requirements of a number of important applications which require APA.
