Abstract— We consider a scenario in which frequency agile radios opportunistically share a fixed spectrum resource with a set of primary nodes. We develop a collaborative scheme...
A key feature of wireless communications is the spatial reuse. However, the spatial aspect is not yet well understood for the purpose of designing efficient spectrum sharing mecha...
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...
