Abstract The Recurrent Transmission Ratio (RTR), considered as confine for Cognitive
Radio Ad-hoc Networks (CRAN), has attracted several researchers' in the recent past …

In multi-channel ad-hoc cognitive radio networks, each channel has different wireless
channel gain and primary activity so that achievable data rate to secondary users (SUs) and …

In cluster-based cognitive radio networks, secondary system uses available channels that
are not used temporally by primary systems. In multi-channel operational environments …

Cognitive radio networks (CRN) has been depicted as one of the most important driving
forces in achieving next generation wireless communication capabilities. To this end …

Though various works have been done for handling end-to-end congestion control in
traditional wireless adhoc networks, they lead to abnormal delay in Cognitive Radio …
