—Cognitive radio presents a new approach to wireless spectrum utilization and management. In this work, the potential performance improvement gained by applying cognitive radio t...
In this paper, the problem about power control in multiuser cognitive networks is addressed. The scenario we study is a heterogeneous network, where multiple cognitive (without the...
—The cognitive radio based IEEE 802.22 wireless regional area network (WRAN) is designed to operate in the under–utilized TV bands by detecting and avoiding primary TV transmis...

Abstract— Transporting video over wireless networks has twofold constraints. Not only should it satisfy delay requirements but power minimization and QoS issues should be handled...
Higher layer protocols in wireless networks need to dynamically adapt to observed network response. The common approach is that each session employs end-to-end monitoring to estim...
