Abstract The Fifth Generation (5G) of wireless communication systems is expected to meet a
large demand for mobile traffic and provide higher data rates, supporting bandwidth-hungry …

With channel assembling strategies (CAS), more capacity and spectrum utilization can be
achieved. However, blocking and forced termination occurs whenever the primary user (PU) …

Integrating cognitive radio into the current power grid is designed to enable smart
communication and decisions within the grid. Communication within the grid is not feasible …

Unlike in overlay cognitive radio networks, secondary users in underlay cognitive radio
networks can access licensed spectrum even at the presence of a primary user, given that …

To maximize the spectrum hole (TV white space), a robust channel allocation policy
featuring aggregation of several primary user idle resources (TVWS) into groups of useable …

The demand for licensed spectrum resources is rapidly on the rise. This is due to the
proliferation of bandwidth consuming wireless services and multimedia applications which …

In this paper, the performance of spectrum adaptation in cognitive radio networks (CRNs)
with elastic traffic is analytically evaluated. Contrary to most of the previously published …

Queuing regime is one outstanding approach in improving channel aggregation. If well
designed and incorporated with carefully selected parameters, it enhances the smooth …

According to the facts and figures published by the international telecommunication union
(ITU) regarding information and communication technology (ICT) industry, it is estimated that …

Channel aggregation (CA) is one of the newest concept which cognitive radio network is
bringing to bear for the smooth role out of fifth/next generation wireless networks. This is the …
