Cognitive radio networks (CRNs) have emerged as an essential technology to enable
dynamic and opportunistic spectrum access which aims to exploit underutilized licensed …

New wireless network paradigms will demand higher spectrum use and availability to cope
with emerging data-hungry devices. Traditional static spectrum allocation policies cause …

In this paper, we focus on a dynamic spectrum access strategy for Internet of Things (IoT)
applications in two types of radio systems: cellular networks and cognitive radio-enabled low …

It is envisaged that in future Cognitive Radio (CR) networks deployment, multiple radio
access networks may coexist. The networks may have different characteristics in terms of …

The recent strides in vehicular networks have emerged as a convergence of multi radio
access networks having different user preferences, multiple application requirements and …

In the cognitive radio ad hoc networks (CRAHNs), the spectrum availability may change from
time to time and hop by hop. Thereby, the performance analysis and optimization for …

In future cognitive radio (CR) vehicular networks deployment, multiple radio access
networks may coexist in overlapping areas. These networks may have with largely different …

Quality of service parameters of cognitive radio, like, bandwidth, throughput and spectral
efficiency are optimized using adaptive and demand based genetic algorithm. Simulation …

Channel handoff is a crucial function for Cognitive radio ad hoc networks (CRAHNs). The
absence of centralized infrastructures and the limited power make the handoff design more …
