“…Although the concept of combining FEC and ARQ is by no means new, our proposed protocol is significantly different from existing hybrid FEC-ARQ literatures (e.g. [1,2,3,4]). These works are concerned with throughput and power for wireless transmission, quality management for real-time media, feedback complexity for scalable multicast, etc.…”

“…That is, each time a channel packet is received, the receiver acknowledges positively and each time a loss is detected, the receiver acknowledges negatively. 2 Let P, N , U respectively be the positively, negatively, and not yet acknowledged channel packets.

Emerging applications with high data rates will need to transport bulk data reliably in wireless sensor networks. ARQ (Automatic Repeat request) or Forward Error Correction (FEC) code schemes can be used to provide reliable transmission in a sensor network. However, the naive ARQ approach drops the whole frame, even though there is a bit error in the frame and the FEC at the bit level scheme may require a highly complex method to adjust the amount of FEC redundancy. We propose a bulk data transmission scheme based on erasure-resilient code in this paper to overcome these inefficiencies. The sender fragments bulk data into many small blocks, encodes the blocks with LT codes and packages several such blocks into a frame. The receiver only drops the corrupted blocks (compared to the entire frame) and the original data can be reconstructed if sufficient error-free blocks are received. An incidental benefit is that the frame error rate (FER) becomes irrelevant to frame size (error recovery). A frame can therefore be sufficiently large to provide high utilization of the wireless channel bandwidth without sacrificing the effectiveness of error recovery. The scheme has been implemented as a new data link layer in TinyOS, and evaluated through experiments in a testbed of Zigbex motes. Results show single hop transmission throughput can be improved by at least 20% under typical wireless channel conditions. It also reduces the transmission time of a reasonable range of size files by more than 30%, compared to a frame ARQ scheme. The total number of bytes sent by all nodes in the multi-hop communication is reduced by more than 60% compared to the frame ARQ scheme.

“…RELATED WORK The QoS guarantee of wireless real-time media streaming has been fairly well studied in the literature [1,[3][4][5][6][7]. Z. MEI et al analyzed the structure of video stream, and presented a frame decoding model that takes into account the frame types and the dependence among frames in [1].…”

“…Q. Zhang et al discussed the combination of the application layer, the transport layer and the data link layer based on a cross-layer design [4]. In [5,6,7], hybrid FEC/ARQ method was adopted. The number of data retransmission is limited to restraint the delay for improving the quality of transmission.…”

This paper proposes a link-level hybrid FEC/ARQ based on an adaptive forward error correction (adaptive FEC) algorithm for wireless media streaming, in the hope that the media could be played on receivers with high quality. This model, which uses adaptive forward error correction mechanism at the application layer to adjust to the current network condition, can maximize the performance of wireless multimedia communication. Our simulation results and mathematical analysis show that the hybrid FEC/ARQ achieves better quality of media streaming comparing with FEC alone and ARQ alone, in terms of playable frame rate, reliability and real-time performance on the receiving side.
