Adaptive Video Streaming Transmission Mechanism Based on Wireless NDN
Xiaojie Ding, Wang Yang, Fan Wu · 2020
With the increase of the video Quality of Experience (QoE), the demand for effective video distribution increases sharply. As the wireless environment changes, it will significantly impact the user's QoE in video streaming. The characteristics of Named Data Networking (NDN), such as multicast and Interest aggregation, which can improve the distribution efficiency of video streaming. However, the current video streaming transmission solution requires a large number of Interest request packets for video segments, which will increase the consumer channel competition in wireless NDN. In this paper, we propose an adaptive video streaming transmission mechanism for wireless NDN, which includes Data Batch Processing Scheme (DBPS) and Adaptive Transmission Scheme (ATS). To reduce the channel competition, we propose the DBPS to reduce the number of Interest sending. In addition, we propose the ATS to adaptively select the transmission mode under the different network conditions, which can improve the user's QoE. Evaluation results show that the proposed scheme of the NDN video streaming transmission mechanism can effectively improve the user's QoE.
