High performance adaptive video streaming using NDN WLAN multicast

Abstract

Multicast is a promising technology for rapidly-increasing video streaming in Wireless Local Area Networks (WLAN). NDN's implicit multicast and caching capabilities provide strong benefits in multicast transmission and can significantly improve network transmission efficiency. However, existing WLAN multicast schemes use the basic data rate to transmit the multicast data. The basic data rate cannot support high-quality video transmission, which significantly reduces the user's Quality of Experience (QoE). In addition, the NDN architecture follows the One-Interest-One-Data transmission principle, so that the uplink will have to face fierce competition, especially when the number of stations has increased significantly. In this paper, we propose HPNM, a High Performance adaptive video streaming scheme by using NDN WLAN Multicast. To improve the Interest sending efficiency in the NDN Live video scenario, we propose an AP(Access Point)-based Interest proxy mechanism that mitigates WLAN channel competition as the number of Interest sending packets increases. In addition, we propose a layer-based NDN WLAN multicast data rate selection mechanism for the adaptive Scalable Video Coding (SVC) video streaming, which can further improve the video bitrate. We use ndnSIM to evaluate the performance of HPNM in terms of video bitrate, startup time, and stalling time. The evaluation results show that the average video bitrate of HPNM has increased significantly compared with the existing scheme in the background traffic scenario.
