With the rapid proliferation of wireless services, the frequency spectrum has become
increasingly crowded, and the interferences and composite signals will be ubiquitous in the …

Offloading assists in overcoming the resource constraints of specific elements, making it one
of the primary technical enablers of the Internet of Things (IoT). IoT devices with low battery …

The explosive increase in number of smart devices hosting sophisticated applications is
rapidly affecting the landscape of information communication technology industry. Mobile …

Due to the ever-increasing wireless service requirements, the issues of a limited frequency
resource and underutilized frequency allocation scheme as well as frequency crowd have …

Cognitive radio (CR) is a wireless technology for increasing the bandwidth usage. Spectrum
sensing (SS) is the first step in CR. There are three basic techniques in SS, energy detection …

As multiple signal classification (MUSIC) algorithm is unable to estimate the direction of
arrival (DOA) of highly correlated or coherent signal, based on array processing and …

In any cognitive radio sensor networks (CRSNs), the secondary users (SUs) and primary
users (PUs) share the opportunity to use the authorized frequency band. Here, the SU nodes …

This Letter addresses the problem of dynamic power allocation based on spectrum sensing
outputs for non-ergodic systems. On such type of systems, the power allocation for each …

Energy detector is the simplest spectrum sensing technique in cognitive radio in terms of
computation complexity as it is developed assuming only channel noises for the detection of …

Spectrum sensing is one of the main parts in cognitive radio. The performance of the
adopted spectrum sensing method is very important. When the primary user and the …
