The rapid progression in wireless networking has raised the demand of extra spectrum
bands. The current fixed spectrum allocation policy used by the government agencies is …

Spectrum bands are the backbone of wireless networks. Every user is allocated a fraction of
the spectrum from available fixed spectrum band. But, the fixed available spectrum band …

Long-Term Evolution (LTE) communication systems feature advanced frequency reuse and
interference coordination techniques providing faster and more secured mobile services …

TV White Spaces constitutes the major portion of the VHF and UHF TV and which is
geographically unused after digital switchover. The most important regulatory trend in the …

This paper focuses on the problem of spectrum sharing between secondary networks that
access spectrum opportunistically in TV spectrum. Compared to the coexistence problem in …

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 …

We investigate the coexistence issue between 802.22 and 802.11 af networks over the TV
White Space (TVWS). The coexistence scheme is vulnerable to selfish attacks. In this paper …

The operation of small cells in TV white spaces (TVWSs) represents a coexistence
challenge due to their unplanned deployment, their heterogeneous transmission …

When white space radio systems of the same type are operating in the same geographic
location, coexistence problem can be solved by self-coexistence mechanisms embedded in …
