In legacy 802.11e, It proposed polling for transmitting allocated TXOP for real-time traffic and proposed multi-polling to reduce overhead and transmit similar data type which exist different frame, together. In existing multi-polling method, they first allocate CBR traffic that became admission control, and then allocate VBR traffic. However, this method may not transmit the data because of delay although TXOP through admission control is allocated in End-to End network. Therefore, we are the novel multi polling method that first allocates the VBR traffic which has low delay rather than the CBR traffic which has high delay. Our method allocate delay-sensitive traffic in advance, so that it can increase the efficiency of transmitting traffic and QoS(Quality of Service). To validate our method, we carried out a simulation study, so that we observed that our proposed method is higher than legacy method at the aspect of throughput and utilization.
