Spectrum sharing is a key technology to relieve the ever-increasing spectrum demand and
realize the full potential of radio spectrum. In this paper, we study spectrum sharing between …

The authors apply the preemptive priority queueing analysis to cognitive radio networks.
Using the proposed analytical model, the authors can quantify the delay, throughput and …

In multi-hop inter-vehicle communications (MHIVC) for cognitive radio (CR), high mobility of
vehicles causes the situation change of the primary user (PU) near the secondary user (SU) …

We consider a channel state acquisition scheme in the cognitive radio (CR) ad hoc system.
Unlike cellular CR systems, the channel state acquisition scheme, which uses a geolocation …

In this paper, we study time spectrum block (TSB) assignment in cognitive radio networks.
We consider a community cognitive radio network with a set of access points (APs), and …

The quality of energy detector is quite challenging when the system parameters are not
stable. On the other hand, in a cognitive radio network, primary users are licensed to use the …

In this paper, throughput analysis is presented for random allocation of channels in a
cognitive radio network. In random allocation, each primary user dynamically and randomly …

In this paper, we propose a resource assignment scheme of a secondary user (SU) for a
multi-hop cognitive radio network. In multi-hop networks, since each link has different SNR …

In recent decades, cognitive radio has been introduced as a practical solution to solve the
frequency scarcity problem by setting up a secondary network besides the primary one …

Cognitive Radio (CR) innovation helps in contriving remote framework for satisfactory
sending of radio range with it's foresee procedure, self-adjustment and range allotment …
