Dalam persekitaran pengkomputeran mudah alih, masalah mungkin wujud antara mekanisme pemulihan kerugian yang digunakan oleh TCP (protokol kawalan penghantaran) dan RLP (protokol pautan radio). Ini kerana penghantaran semula tempatan yang dilakukan oleh RLP boleh mengganggu pemulihan ralat hujung ke hujung TCP apabila terdapat kehilangan paket yang panjang dan berkorelasi akibat ralat saluran pecah. Iaitu, tamat masa palsu akan berlaku pada lapisan pengangkutan. Dalam makalah ini, kaedah baharu dicadangkan untuk menyekat berlakunya tamat masa palsu TCP dengan berkesan. Dalam kaedah baharu ini, sebilangan kecil ACK (pengiktirafan) ditimbal di stesen pangkalan sebelum kemunculan setiap tempoh keadaan buruk dalam saluran wayarles, dan ACK ini seterusnya dikeluarkan oleh stesen pangkalan satu demi satu untuk menetapkan semula TCP pemasa penghantaran semula penghantar. Perbandingan menyeluruh antara kaedah yang dicadangkan dan kaedah garis dasar dijalankan melalui simulasi untuk menunjukkan bahawa peningkatan dalam prestasi pemprosesan boleh mencapai sebanyak 22%.

Abstract: In mobile computing environments, a problem may exist between loss recovery mechanisms employed by the TCP (transmission control protocol) and RLP (radio link protocol). It is because that local retransmissions performed by the RLP could interfere with the TCP end-to-end error recovery when there are long and correlated packet losses due to bursty channel errors. That is, a spurious timeout would occur at the transport layer. In this paper, a new method is proposed to effectively suppress the occurrence of TCP spurious timeouts. In this new method a small number of ACKs (acknowledgements) is buffered at the base station prior to the emergence of every bad state period in the wireless channel, and these ACKs are henceforth released by the base station one at a time to reset the TCP sender's retransmission timer. Comprehensive comparisons between the proposed method and a baseline method are conducted through simulations to show that the improvement in throughput performance can be as large as 22%.
