Mobility Management in Cellular Network Based On Cognitive Radio

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 while roaming from another service provider. 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 cells as well as inter cell mobility management for efficient spectrum sharing technique. I proposed a pool based spectrum management where the spectrums are managed in a group called pool such that the base stations can appropriately choose the pool depending upon network load and perform spectrum switching. I use frequency domain sensing technique to effectively sense the free spectrum. Simulation result shows high accuracy in free spectrum detection and handoff.
