| Abstract: | The existing problems of the QoS multimedia services in IEEE802.16 are discussed and the disadvantage and advantage of current bandwidth scheduling strategy based IEEE802.16 are analyzed.An improvement strategy of IEEE802.16 PMP network model is proposed based on existing strict priority scheduling strategy.Finally,through the simulation data,it is proved that the strategy can ensure the QoS performance and fairness of bandwidth allocation between various multimedia communication services. |
