Spectrum auction is an emerging economic scheme to stimulate both primary spectrum
operators (POs) and secondary users (SUs) to be involved in spectrum sharing. Previous …

Under-utilization of wireless spectrum by the licensed owners creates spectrum holes which
can be opportunistically exploited by secondary users (SUs). By incorporating dynamic …

Auction is often applied in cognitive radio networks due to its efficiency and fairness
properties. An important issue in designing an auction mechanism is how to utilize the …

Cognitive radio (CR) is applied to solve spectrum scarcity. Although the auction theory and
learning algorithm have been discussed in previous works, their combination is not yet …

Fair allocation of unused licensed spectrum among preferable secondary users (SUs) is an
important feature to be supported by Cognitive Radio (CR) for its successful deployment …

In order to fully utilize spectrum, auction-based dynamic spectrum allocation has become a
promising approach which allows unlicensed wireless users to lease unused bands from …

Spectrum auction has been considered as an economically incentive way to motivate both
primary spectrum owners (POs) and secondary users (SUs) to participate in dynamic …

With the increasing number of handheld and mobile devices, the demand for available
spectrum resource is experiencing a rapid growth. Auction has been widely used for …

In this paper, we tackle the spectrum allocation problem in cognitive radio (CR) networks
with time-frequency flexibility consideration using combinatorial auction. Different from all …

For the recent decade, cognitive radio networks have received much attention as an
alternative to the traditional static spectrum allocation policy since the licensed spectrum …
