Security Spectrum Auction Framework for Cognitive Radio Networks

Spectrum auction is an effective way to improve spectrum efficiency in cognitive networks. All traditional auction framework such as VCG price auction framework and second price auction framework face security risks. Collusion is the most important risk in multi-user cognitive networks. In this paper, we propose a security mechanism for the multi-user cognitive spectrum auction networks. This s...

Auction and Game-Based Spectrum Sharing in Cognitive Radio Networks

One of the main reasons behind the concurrent increase in the demand for and congestion of Radio Frequency (RF) spectrum is the rapid development of radio networks of all kinds in our world, which has defiantly changed the public feeling about radio. Nowadays, almost everybody has a mobile phone and radio stations are literary everywhere. Someone can argue that our world is becoming a radio wor...

Optimal Auction Mechanism for Spectrum Allocation in Cognitive Radio Networks under Uncertain Spectrum Availability

In this paper, we consider the problem of dynamic spectrum allocation in cognitive radio (CR) networks and propose a new sealed-bid auction framework to address the spectrum allocation problem when the spectrum is not available with certainty. In our model, we assume that the moderator plays the dual role of being a fusion center (FC) for spectrum sensing and an auctioneer for spectrum allocati...

Spectrum Sharing Games of Infrastructure-Based Cognitive Radio Networks

The IEEE 802.22 standard is the first proposed standard for the cognitive radio networks in which a set of base stations (BSs) make opportunistic spectrum access to provide wireless access to the customer-premise equipments (CPE) within their cells in wireless regional area networks (WRAN). The channel assignment and power control must be carried out in BSs and CPEs, such that no excessive inte...
