Query: Quantum Game Application to Spectrum Scarcity Problems   Recent spectrum-sharing research has produced a strategy to address spectrum
scarcity problems. This novel idea, named cognitive radio, considers that
secondary users can opportunistically exploit spectrum holes left temporarily
unused by primary users. This presents a competitive scenario among cognitive
users, making it suitable for game theory treatment. In this work, we show that
the spectrum-sharing benefits of cognitive radio can be increased by designing
a medium access control based on quantum game theory. In this context, we
propose a model to manage spectrum fairly and effectively, based on a
multiple-users multiple-choice quantum minority game. By taking advantage of
quantum entanglement and quantum interference, it is possible to reduce the
probability of collision problems commonly associated with classic algorithms.
Collision avoidance is an essential property for classic and quantum
communications systems. In our model, two different scenarios are considered,
to meet the requirements of different user strategies. The first considers
sensor networks where the rational use of energy is a cornerstone; the second
focuses on installations where the quality of service of the entire network is
a priority.
