Cognitive radio (CR) technology offers a promising solution to the spectrum scarcity problem via dynamic spectrum access (DSA). Due to the nature of cooperative cognitive radio networks (CRNs), where two distinct networks are active simultaneously, a significant amount of control messaging is required in order to coordinate channel access, schedule sensing, and establish and release connections. Efficient control plane messaging can be achieved by the selection of an appropriate control channel… CONTINUE READING

Key Quantitative Results

  • In order to compare the performance of all of the studied selection strategies, Tables 2 and 3 expand on the findings that were presented in Section IV. A. Robustness Against PUs’ Activity From the simulations, we notice that both underlay and SP selection strategies are robust against PUs’ activity and can achieve a success rate of 95% and 92%, respectively, in the airport environment when λPU is either 0.1 or 0.9, λSU = 0.1 and number of SUs = 100.
  • For the outdoor stadium environment, the same comment applies, with a success rate of 100 and 99% for the underlay and SP selection strategies, respectively, with an achieved throughput of 4 Mbps and 6 Mbps, respectively.
