Main Reference PapereDSA: Energy-Efficient Dynamic Spectrum Access Protocols for Cognitive Radio Network, IEEE Transactions on Mobile Computing, 2016 [NS2].
  • An energy efficient dynamic spectrum access (eDSA) protocol is proposed for the cognitive radio (CR) networks. The proposed approach accounts for the realistic traffic and primary transmission characteristics, and the protocols are aimed at maximizing the (secondary user) SU channel utilization without degrading the PU performance below a predefined threshold. Via rigorous Markov modeling, protocol performance, as well as PU collision ratio have been captured. A simple PU channel activity parameter estimation technique has also been presented, which is used for dynamic adjustment of SU operating parameters according to the PU traffic.
