Handover based spectrum allocation in cognitive radio networks

There is a rapid development in wireless technologies with the increase of congestible frequency spectrums, research study reveals that there is a problem in spectrum management and spectrum allocation. To overcome this problem there is a new technology known as cognitive radio technology in wireless sensor networks called as CWSNs. The first standard for cognitive radio networks is IEEE 802.22, but this standard cannot overcome the problem of spectrum management and spectrum allocation. In this paper we propose a novel protocol in which spectrum allocation can be done by increasing the transmission range and communication quality, lowering the energy consumption and delays.
