Abstract |
|
Cognitive radio is emerging wireless technology which offers reallocation and reutilization of the unused spectrum. Not all the network runs with highest load at all the time. Therefore part of spectrum always remains unused. In a multi radio environment cognitive radio allows the user to request for spectrum from another service provider while roaming. In case the service provider has free spectrum, it can reallocate the spectrum to the demanding user. In this work we provide a mechanism for managing both intra cell as well as inter cell mobility management for efficient spectrum sensing technique. We propose a pool based spectrum management where the spectrums are managed in a group called pool such that the base stations can appropriately chose the pool depending upon network load and perform spectrum switching. |
