The problem of spectrum scarcity and inefficiency in spectrum usage will be addressed by the newly emerging cognitive radio paradigm that allows radios to opportunistically transmit in the vacant portions of the spectrum already assigned to licensed users. For this, the ability for spectrum sensing, spectrum sharing, choosing the best spectrum among the available options, and dynamically adapting transmission parameters based on the activity of the licensed spectrum owners must be integrated…

Spectrum management in cognitive radio networks
In this talk, an overview of the cognitive radio technology is provided and the network architecture is introduced, and the cognitive network functions such as spectrum management, spectrum mobility and spectrum sharing are explained in detail.
Optimization of spectrum management in cognitive radio networks.
The author presents a sequential sensing based spectrum handoff policy for multiple users in CRNs, and proposes a cluster-based adaptive multi-spectrum sensing and access strategy, in which the SUs seeking to access the channel can select a set of channels to sense and access with adaptive sensing time.
Spectrum hand off in Cognitive Radio Network using Dynamic Threshold
A suitable hand off scheme has been proposed whose objective is to help cognitive user to find suitable channel to resume the unfinished transmission as quickly as possible and simulation results of the proposed scheme show that the model works well in increasing the throughput and packet delivery ratio in Cognitive Radio Networks.
