Abstract

In this paper, we propose a network-adaptive transport error control (TEC) mechanism over the IEEE 802.11b wireless LAN (WLAN). The proposed TEC mechanism adaptively combines packet-level FEC (forward error correction) and interleaving based on the monitored network status. The FEC component is designed to combat the varying packet loss (i.e., erasure) rate while the interleaving is addressing the burstiness of packet losses. By using end-to-end monitoring combined with the packet transport, the receiver sends feedbacks about the measured packet loss rate and delay. The proposed TEC mechanism adjusts the level of error protection according to the latest status of underlying IEEE 802.11b WLAN. To verify the feasibility of the proposed TEC mechanism, we have evaluated the transport performance over the real IEEE 802.11b WLAN testbed as well as over the emulated WLAN environment. The experimental results show that the proposed mechanism can enhance the reliability of video streaming.
