State of the Art
• Jumbo Frames
– Proprietary solutions for frame aggregations [Atheros
Super G, TI frame concatenation]
– 802.11n frame aggregation standard
• Require specific hardware support
• Entire packet needs to be retransmitted
• Partial Packet Recovery
– Require specific hardware support [MRD, SOFT, PPR]
– Leverage PHY layer information [SOFT, PPR]
• if PHY layer information is available, FRJ can benefit to
provide higher gain
• Rate Adaptation
– SampleRate, ONOE (madwifi), RRAA
– Over-estimates the actual loss rate
• Adapt rate according to frame loss rate
• Over-estimates the actual loss rate
Holistic Approach is missing !
