Abstract(in English) | In this report, we assess the effect of reliable groupcast schemes on QoE of audio and video IP transmission over a wireless LAN. As reliable groupcast schemes, we use GCR (GroupCast with Retries) Unsolicited Retry and GCR Block Ack; they are standardized by IEEE 802.11aa. We assume that a wireless access point transmits audio and video streams to several terminals connected to the access point by groupcast. We compare three schemes: groupcast with EDCA (Enhanced Distributed Channel Access), GCR Unsolicited Retry and GCR Block Ack. We perform a computer simulation under various network conditions to assess application-level QoS and evaluate QoE by a subjective experiment. As a result, we find that GCR Block Ack shows higher QoE than the other two schemes under various network conditions. |
