Untuk meningkatkan kecekapan pemprosesan protokol ARQ melalui saluran ralat paket rawak yang tinggi, strategi penghantaran salinan berbilang (CMCT) bersebelahan yang mana setiap paket dihantar (semula) dengan menghantar berbilang salinannya dalam slot bersebelahan telah digunakan setakat ini. Walau bagaimanapun, dalam persekitaran ralat pecah, semua salinan mungkin rosak dalam pecah ralat yang mengakibatkan kemerosotan prestasi CMCT. Untuk menghadapi situasi ini, kami mencadangkan, dalam kertas ini, strategi baharu yang dipanggil intermittent multiple copy-transmission (IMCT) di mana berbilang salinan dihantar pada selang masa yang tetap. Kecekapan pemprosesan go-back-N ARQ menggunakan CMCT atau IMCT dianalisis dan dipertimbangkan di bawah model saluran Markov dua keadaan yang menyatakan sifat ralat pecah saluran. Hasilnya, ditunjukkan bahawa (i) tahap peningkatan kecekapan pemprosesan oleh CMCT atau IMCT bergantung pada tahap pecah ralat dan (ii) IMCT yang dicadangkan boleh meningkatkan kecekapan pemprosesan go-back-N ARQ untuk tinggi. dan saluran ralat pecah.

Abstract: To improve the throughput efficiencies of ARQ protocols over a high random packet-error channel, contiguous multiple copy-transmission (CMCT) strategy for which each packet is (re-)transmitted by sending its multiple copies in contiguous slots has been used so far. However, in burst error environments, all copies may be damaged in an error burst resultting the performance degradation of CMCT. To cope with this situation, we propose, in this paper, a new strategy called intermittent multiple copy-transmission (IMCT) whereby multiple copies are sent at a fixed interval. The throughput efficiency of go-back-N ARQ using CMCT or IMCT is analyzed and considered under a two-state Markov channel model expressing burst error property of a channel. As a result, it is shown that (i) the degree of improvement of throughput efficiency by CMCT or IMCT depends on the degree of error burst and (ii) the proposed IMCT can improve the throughput efficiency of go-back-N ARQ for high and burst error channels.
