In this paper, we considered the performances of PMIPv6 and DMM in the viewpoints of traffic load change and packet delivery latency time, where a new buffering in the previous MAAR is proposed to reduce packet loss during handover. To show the superiority of the DMM and to validate the operation of the buffering scheme, we accomplished its simulation under the typical handover. Our performance comparison results show that the DMM is better than the performance of traffic load change and packet delivery latency time of PMIPv6. We can see that the proposed buffering scheme is better than the existing one in terms of packet loss.
