Cooperative 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,...
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 کاملOptimal Channel and Power Allocation for Secondary Users in Cooperative Cognitive Radio Networks - (Invited Paper)
Cognitive radios are a natural evolution of Software Defined Radios (SDRs) that are supposed to be equipped with the ability to learn their RF environment and reconfigurability. A cognitive radio can communicate over a primary user’s channel as long as the introduced interference does not degrade the primary Single-to-Interference-plusNoise-Ratio (SINR) below its minimum Quality of Service (QoS...

متن کاملOn Network Selection for Secondary Users in Cognitive Radio Networks
In this paper, we present a network flow based approach for network selection for secondary users in cognitive radio networks. Most approaches in the current literature on cognitive radio do not consider network selection. We present a network flow framework for network selection. We show that our approach can enable re-assignment of networks to secondary users and also re-assignment of channel...
