In this paper, we apply the combinatorial auction scheme to solve the spectrum allocation
problem under heterogeneous supply and demand in cognitive radio networks. The …

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 …

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 …

Recently, many dynamic spectrum allocation schemes based on economics are proposed to
improve spectrum utilization in cognitive radio networks (CRNs). However, existing …

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 this paper, we investigate spectrum trading via auction approach for exclusive usage
spectrum access model in cognitive radio networks. We consider a realistic valuation …

Cognitive radio (CR) has evolved as a novel technology for overcoming the spectrum-
scarcity problem in wireless communication networks. With its opportunistic behaviour for …

Cognitive Radio (CR) is a promising concept to improve spectrum utilization of the existing
spectrum bands. In this paper, spectrum sharing problem between primary users (licensed) …

Cognitive radio is a novel communication paradigm that can significantly improve spectrum
utilization by allowing the cognitive radio users to dynamically utilize the licensed spectrum …

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 …
