This paper proposes a new paradigm for spectrum sharing between cellular wireless
communications (CWC) and radio astronomy systems (RAS). In contrast to the existing …

Rapid progress in software, hardware, mobile networks, and the potential of interactive
media poses many questions for researchers, manufacturers, and operators of wireless …

Although the Moore's law is slowing down in terms of technology node scaling, researchers
are inventing new methods to keep the design productivity on the rising trend. As a …

Cognitive Radio becomes a new technology for increasing the spectrum efficiency by means
of creating opportunistic transmission links. Maintaining the routing information to …

A conflict of the spectrum rights and needs between active wireless communication systems
and passive radio astronomy systems (RASs) has become substantially greater due to the …

The link failure due to the secondary users exiting the licensed channels when primary
users reoccupy the licensed channels is very important in cognitive wireless mesh networks …

Cognitive radio networks are becoming popular day by day as the need for spectrum is
increasing. Its ability to use and reuse the underutilized spectrum makes it a very impressive …

In this thesis, we present a new architecture for application-aware cognitive multihop
wireless networks (AC-MWN) with testbed implementations and experiments. Cognitive …
