In this paper, we propose an Automatic Repeat reQuest (ARQ) technique for enhancing the reliability anti throughput of broadband wireless Internet access applications, and provide examples of its performance. ARQ is a method for making a link anti How more robust to errors. Other than enhancing link quality ARQ provides early error recovery, so that the transport layer does not lower the data throughput. T he cost of these enhancements is additional overhead. In this work, we have extensively analyzed our proposed ARQ scheme along with realistic wireless channel anti protocol stack models. We have quantified the performance gains of our ARQ scheme as reduced end-to-end delay, increased throughput, SNR gain anti fade margin, also providing the overhead costs. We have proposed anti analyzed enhanced features, namely Segmentation anti Reassembly (SAR) anti Bitmap Compression. We showed that these features reduce the overhead, the extent of which depends on the nature of the errors.
