Virginia Tech Tackles the DARPA Spectrum Collaboration Challenge

DARPA logoA team of researchers from Virginia Tech has been awarded a $2,000,000 grant from the Defense Advanced Research Projects Agency (DARPA) to participate in the Spectrum Collaboration Challenge. This grand challenge focuses on developing new techniques for collaboration between radios (using machine-learning) to overcome scarcity in the radio frequency spectrum. In this program, teams from around the world will compete to reimagine a new, more efficient wireless paradigm in which radio networks autonomously collaborate to dynamically determine how the spectrum should be used moment to moment.

The team, led by R. Michael Buehrer, professor of electrical and computer engineering (ECE) and director of Wireless @ Virginia Tech and Robert McGwier, chief scientist at the Hume Center for National Security and Technology, will participate in several rounds of competition through this program, developing unique technologies at each phase. Professors Jeffrey Reed and Jung-Min “Jerry” Park (both professors in ECE and well-known researchers in the area of spectrum sharing) are also part of the Virginia Tech team.

Buehrer noted that “Our team is very excited to be a part of this program. The contest has the potential to completely change the way wireless networks are designed and spectrum is utilized. Just as autonomous vehicles have the potential to fundamentally change the way transportation is done, machine intelligence and collaboration innovations have the potential to change the way communication networks are deployed.” While the radio spectrum itself is finite, the increase of wireless products, such as smart phones, that are using the radio spectrum has increased dramatically in recent years and is projected to continue to increase in the foreseeable future. The ability to manage the radio spectrum efficiently is one of the greatest challenges of our time.

The Virginia Tech team is also sponsored by Lockheed Martin's Advanced Technology Laboratories. The winning team from this multi-year effort could win as much as $3.5M.

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
