Spectrum pooling and unlicensed spectrum access by cognitive radios can compensate for spectrum scarcity, caused by static licensing policies, by utilizing spectrum opportunities. In this work we modify CSMA/CA MAC protocol for operation over a spectrum pooling environment and for secondary, overlay, distributed cognitive radio networks. New performance limits and design - tradeoffs are discovered. Moreover, a new MAC protocol is proposed to improve CSMA/CA throughput over spectrum pooling. All… CONTINUE READING
