Apabila TCP beroperasi dalam rangkaian wayarles berbilang hop, ia mengalami kemerosotan prestasi yang teruk. Ini kerana TCP bertindak balas terhadap kehilangan paket tanpa wayar dengan mengurangkan kadar penghantarannya secara tidak perlu. Walaupun algoritma pembezaan kerugian sebelumnya (LDA) boleh mengenal pasti beberapa kehilangan paket akibat ralat penghantaran tanpa wayar sebagai kerugian tanpa wayar, ketepatannya tidak tinggi seperti yang kita jangkakan, dan skim ini tidak dapat mengelak daripada mengorbankan ketepatan diskriminasi kehilangan kesesakan dengan salah mengklasifikasikan kesesakan. kerugian sebagai kerugian tanpa wayar. Dalam makalah ini, kami mencadangkan skim pembezaan kerugian hujung ke hujung baharu yang mempunyai ketepatan tinggi dalam diskriminasi kehilangan wayarles dan diskriminasi kehilangan kesesakan. Skim kami menganggarkan kadar penggunaan baris gilir menggunakan maklumat yang tersedia untuk TCP. Jika anggaran penggunaan baris gilir adalah lebih besar daripada 50% apabila satu paket hilang, skim kami mendiagnosis kehilangan paket sebagai kehilangan kesesakan. Jika tidak, ia mendiagnosis kehilangan paket sebagai kerugian tanpa wayar. Oleh kerana anggaran penggunaan baris gilir sangat berkaitan dengan kesesakan, skim kami mempunyai kelebihan untuk mengenal pasti kehilangan paket yang berkaitan dengan kesesakan dan yang tidak berkaitan dengan kesesakan dengan lebih tepat. Melalui simulasi yang meluas, kami membandingkan dan menilai skema kami dengan LDA sebelumnya dari segi korelasi, ketepatan dan kestabilan. Dan keputusan menunjukkan bahawa skim kami mempunyai ketepatan tertinggi serta ketepatannya lebih dipercayai daripada LDA yang lain.

Abstract: When TCP operates in multi-hop wireless networks, it suffers from severe performance degradation. This is because TCP reacts to wireless packet losses by unnecessarily decreasing its sending rate. Although previous loss differentiation algorithms (LDAs) can identify some of the packet losses due to wireless transmission errors as wireless losses, their accuracy is not high as much as we expect, and these schemes cannot avoid sacrificing the accuracy of congestion loss discrimination by misclassifying congestion losses as wireless losses. In this paper, we suggest a new end-to-end loss differentiation scheme which has high accuracy in both wireless loss discrimination and congestion loss discrimination. Our scheme estimates the rate of queue usage using information available to TCP. If the estimated queue usage is larger than 50% when a packet is lost, our scheme diagnoses the packet loss as congestion losses. Otherwise, it diagnoses the packet loss as wireless losses. Because the estimated queue usage is highly correlated to congestion, our scheme has an advantage to more exactly identify packet losses related to congestion and those unrelated to congestion. Through extensive simulations, we compare and evaluate our scheme with previous LDAs in terms of correlation, accuracy, and stability. And the results show that our scheme has the highest accuracy as well as its accuracy is more reliable than the other LDAs.
