Reduced-Delay Selective ARQ for Low Bit-Rate Image and Multimedia Data Transmission
Tuyet-Trang Lam, Lina J. Karam, Rida A. Bazzi, Glen P. Abousleman · 2006
The paper presents a reduced-delay selective-ARQ scheme based on a similarity check function that measures the degree of corruption in transmitted multimedia data packets. Accordingly, if the packet is found to be badly corrupted based on a specified similarity criterion, it can be considered as a lost packet and retransmitted. The degree of corruption contributed by a particular packet is measured by the proposed similarity check function at the receiver without explicit knowledge of the original source data. Simulation results and comparisons with a conventional ARQ scheme are provided to illustrate the performance of the proposed method.
