This paper proposes an extension to high throughput WLANs such as IEEE 802.11n and IEEE 802.11ac for efficient streaming of H264/AVC encoded videos. The main idea is to fragment IP packets containing several TS packets into smaller IP packets containing fewer TS packets which leads to higher transmission success rate and TS level prioritization of H264/AVC frames. Unlike existing fragmentation schemes, it is done without any modification to the MAC layer at the receiver side. Evaluation results show that the proposed scheme achieves up to 5 dB gain on PSNR and 3.5 times higher goodput than legacy WLANs.
