Quality of experience based scheduling algorithm in LTE network with various traffics

Quality of experience (QoE) based scheduling algorithm of long term evalution (LTE) network with various traffics is studied. Utility functions are adopted to estimate mean opinion score (MOS) for different traffics and a new MOS metric called normalized MOS is defined. A scheduling algorithm based on normalized MOS and greedy algorithm is proposed, aiming at maximizing the entirety MOS level of the whole users in the cell. We compare the performance of the proposed algorithm with other typical scheduling algorithms and the simulation results show that the algorithm proposed outperform other ones in term of QoE and fairness.
