Wireless networks and devices have rapidly been gaining popularity over their wired counterparts. This popularity, in turn, has been generating an explosive and ever-increasing dem...
We consider opportunistic spectrum access (OSA) strategies for a transmitter in a multichannel wireless system, where a channel may or may not be available and the transmitter must...
Abstract—In decentralized cognitive radio (CR) networks, enabling the radios to establish a control channel (i.e., “rendezvous” to establish a link) is a challenging problem....
