resource allocation cognitive radio network orthogonal frequency division multiple access(OFDMA) quality of user experience mean opinion score
A resource allocation protocol is presented in an orthogonal frequency division multiple access(OFDMA)cognitive radio(CR)network with a hybrid model which combines overlay and underlay models. Without disrupting the primary user(PU)transmissions, the overlay model allows the secondary user(SU)to utilize opportunistically the idle sub-channels; the underlay model allows the SU to occupy the same sub-channels with PU. The proposed protocols are designed for maximizing the quality of experience(QoE)of CR users and switching dynamically between the overlay and underlay models. QoE is measured by the mean opinion score(MOS)rather than simply fulfilling the physical and medium access control(MAC)layer requirements. The simulations considering the file transfer and video stream services show that the proposed resource allocation strategy is spectrum efficient.
