An improved fair channel hopping protocol for dynamic environments in cognitive radio networks

Rendezvous is a fundamental challenge in cognitive radio networks where users can find each other on a specific channel and hence establish a communication link. Most previous works are based on the strong assumption that users are able to find a set of available channels after the spectrum sensing stage and the status of these channels are stable all the time, which, however, may be unrealistic in some scenarios. As a solution, we design a fair...
