A Major concern in the past years was the traditional static spectrum allocation which gave rise to spectrum underutilization and scarcity in wireless networks. In an attempt to solve this problem, cognitive radios technology ...

The Wireless Mesh Networks (WMNs) technology has recently emerged as a promising high-speed broadband communication. In a multi hop ad hoc cognitive radio network(CRN)environment, the performance of the network is degraded ...

Cognitive radio network, which enables dynamic spectrum access, addresses the shortage of radio spectrum caused by ever-increasing wireless technology. This allows efficient utilisation of underutilised licenced spectrum ...
