A cognitive wireless sensor network is considered, where a cluster of secondary sensors
utilize channel vacancies of a primary network and transmit their measurement samples to a …

Cognitive radio networks (CRNs) are an emerging paradigm for next generation wireless
communication systems allowing for more efficient radio spectrum utilization. In order to …

Cognitive radio networks (CRNs) rely on sensing of the licensed spectrum of a primary
network to dynamically ascertain underutilized portion of the spectrum, thus affording …

With the advent of various emerging wireless products, the usage of limited spectrum has
grown exponentially in the recent years. In the next few years, that mobile data traffic …

Rapid development in wireless networks has largely raised the demand for spectrum
bandwidth. However, current static spectrum allocation policy is unable to meet this ever …

Handoff in a cognitive radio networks (CRNs) is a situation that arises whenever a
secondary user (SU) has to switch from its current channel to a new target channel in case …

The advancements in wireless communication go in leaps and bounds ushering in due
attention to spectrum sharing. Spectrum scarcity is one of the major limitations causing …

This paper proposes a network tomography scheme for information-centric networking
(ICN), which we call ICN tomography. When content is received over a conventional IP …

In this paper, we consider the transmission needs of communication networks for two
classes of secondary users (SUs), named SU1 and SU2 (lowest priority) in cognitive radio …

Spectrum handoff in cognitive radio networks is to have a seamless switch between
channels consequently, a high quality of service for the secondary users. This paper …
