Spectrum auction with interference constraint for cognitive radio networks with multiple primary and secondary users
Extensive research in recent years has shown the benefits of cognitive radio technologies to improve the flexibility and efficiency of spectrum utilization. This new communication paradigm, however, requires a welldesigned spectrum allocation mechanism. In this paper, we propose an auction framework for cognitive radio networks to allow unlicensed secondary users (SUs) to share the available sp...
متن کاملAuction 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...
متن کاملDistributed Algorithm for Multiple Antenna Cooperative Cognitive Radio Networks with Multiple Primary and Secondary Users
We propose a distributed spectrum access algorithm for cognitive radio relay networks with multiple primary users (PU) and multiple secondary users (SU) utilizing multiple antennas at their transmitter. The overlay model is considered, where the PUs allow spectrum access opportunities for the SUs, in exchange for the SUs cooperatively relaying the PUs’ data in exchange for both spectrum access ...
متن کاملSecurity 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...
متن کاملCooperative Cognitive Radio for Multiple Primary and Secondary Users
We propose a distributed spectrum access algorithm for cognitive radio relay networks with multiple primary users (PU) and multiple secondary users (SU). The key idea behind the proposed algorithm is that the PUs negotiate with the SUs on both the amount of monetary compensation, and the amount of time the SUs are either (i) allowed spectrum access, or (ii) cooperatively relaying the PU’s data,...
