Spectrum Challenge

Radios are used for a wide range of tasks, from the most mundane to the most critical of communications, from garage door openers to military operations. As the use of wireless technology proliferates, radios and communication devices often interfere with and disrupt other wireless devices. First responder radios need to be able to communicate reliably in such congested and contested environments and to share radio spectrum without direct coordination or spectrum preplanning.

The DARPA Spectrum Challenge aims to stimulate the development of innovative approaches to adaptive, software-based radio communications in such multi-user environments. Teams will compete to create protocols for software-defined radios that best use communication channels in the presence of other dynamic users and interfering signals. The Challenge is not focused on developing new radio hardware, but instead seeks algorithmic strategies for guaranteeing successful communication in the presence of other radios without explicit coordination.

The Spectrum Challenge will conduct a sequence of head-to-head competitions between each team's software radio protocols on a standardized software-defined radio hardware platform. The team whose software most reliably achieves successful communication in the presence of other competing radios could win as much as $150,000. For more information, visit the DARPA Spectrum Challenge webpage at www.darpa.mil/spectrumchallenge.


If you follow that 2nd link, you get this:

SPECTRUM CHALLENGE

The final event took place at DARPA's offices in Arlington, VA. Ninety teams registered from around the world as entrants to the Spectrum Challenge and eighteen teams were selected to participate as finalists. Academic institutions from around the country comprised 14 of the 18 teams, with the remaining 4 teams composed of individual radio hobbyists and practitioners working on their own time.

We would like to thank all the participants for their hard work and dedication. Congratulations to all the teams that made it to the finals and a special congratulation to the teams that won.

More information on the event and winners can be found under News and Updates
What is the DARPA Spectrum Challenge?

The DARPA Spectrum Challenge was a competition to demonstrate a radio protocol that can best use a given communication channel in the presence of other dynamic users and interfering signals. The Challenge was not focused on developing new radio hardware, but instead was targeted at finding strategies for guaranteeing successful communication in the presence of other radios that may have conflicting co-existence objectives. The Spectrum Challenge entailed head-to-head competitions between each team’s radio protocol and an opponent’s in a structured testbed environment. The Challenge awarded first place teams in the preliminary event, and first and second place teams in the final event with cash prizes totaling $200,000.
Why is DARPA interested in spectrum usage?

Radios are used for a wide range of tasks, from the most mundane to the most critical of communications, from garage door openers to military operations. As the use of wireless technology proliferates, radios can often compete with, interfere with, and disrupt the operations of other radios. DARPA seeks innovative approaches that ensure robust communications in such congested and contested environments. Other factors that motivate the need for intelligent use of spectrum include:

High priority radios in the military and civilian sectors must be able to operate regardless of the ambient electromagnetic environment, to avoid disruption of communications and potential loss of life.

Response operations, such as disaster relief, further motivate the desire for multiple radio networks to effectively and efficiently share the spectrum without requiring direct coordination or spectrum preplanning

Cyber Grand Challenge Announces 1st Group of Teams, Final Event at DEF CON

Computer security experts from academia, industry and the larger security community have organized themselves into more than 30 teams to compete in DARPA’s Cyber Grand Challenge—a first-of-its-kind tournament designed to speed the development of automated security systems able to defend against cyberattacks as fast as they are launched. DARPA also announced today that it has reached an agreement to hold the 2016 Cyber Grand Challenge final competition in conjunction with DEF CON, one of the largest computer security conferences in the world.

DARPA’s Cyber Grand Challenge takes aim at an increasingly serious problem: the inadequacy of current network security systems, which require expert programmers to identify and repair system weaknesses—typically after attackers have taken advantage of those weaknesses to steal data or disrupt processes. Such disruptions pose greater risks than ever as more and more devices, including vehicles and homes, get networked in what has become known as “the Internet of things.”

“Today’s security methods involve experts working with computerized systems to identify attacks, craft corrective patches and signatures and distribute those correctives to users everywhere—a process that can take months from the time an attack is first launched,” said Mike Walker, DARPA program manager. “The only effective approach to defending against today’s ever-increasing volume and diversity of attacks is to shift to fully automated systems capable of discovering and neutralizing attacks instantly.”

Unlike the previous DARPA project I was not directly involved with this project; but it resembles the spectral challenge, because I only documented the measurable results. In the spectrum challenge, Chinese satellites were discovered disrupting more types of communications than radios. Now intelligence agencies of many nations will participate on computers involved in this network of illegal eavesdroppers, although these volunteers do not realize their computers are disabling enemies who disrupt inernational computer activity. Finally, this activity resembles the spectral challenge initiated, on an international basis by Jeffersons Ghost at 7:13 on 11/19/14.
