heal.abstract	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 work1 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 MAC protocols are evaluated through extensive simulations. © 2007 IEEE.	en
