Sebilangan hos mudah alih mungkin tinggal padat di kawasan yang disebabkan oleh kesesakan lalu lintas. Sebahagian besar hos mudah alih akan memerlukan data yang biasa berguna, seperti maklumat trafik, maklumat tempat letak kereta dan maklumat berkaitan pemanduan lain dalam persekitaran sedemikian. Siaran penghantaran data serentak menggunakan pautan biasa dianggap sebagai cara yang sesuai untuk mengedarkan maklumat yang bergantung kepada lokasi ini. Walau bagaimanapun, tiada jaminan bahawa hos mudah alih boleh selesai menerima maklumat sepenuhnya dalam masa yang terhad. Dalam kertas ini, kami mencadangkan kaedah penghantaran semula data untuk komunikasi antara stesen pangkalan dan hos mudah alih dan kaedah pemprosesan pemulihan data untuk digunakan antara stesen pangkalan. Kaedah penghantaran semula data yang dipanggil "TOA" (The Order of Arrival) menjadualkan data penghantaran semula yang dinyatakan dalam permintaan NACK pertama yang diterima selepas pemprosesan penghantaran semula. Kami telah mencadangkan sistem Sertai "Lanjutan" di mana stesen pangkalan membuat permintaan gabungan disatukan kepada kumpulan berbilang siaran bagi pihak hos mudah alih. Menggunakan kaedah TOA untuk menghantar semula dalam sistem Advanced Join, kecekapan penerimaan data adalah lebih tinggi berbanding dengan sistem Advanced Join yang ringkas dan bilangan mutlak penerimaan data hos mudah alih yang lengkap adalah lebih tinggi. Menggunakan kaedah TOA, walaupun dengan kadar pelupusan stesen pangkalan sebanyak 50%, bilangan penerimaan yang lengkap adalah lebih tinggi daripada dengan sistem Advanced Join pada 80%. Sistem multicasting yang dicadangkan kepada rangkaian ITS berasaskan DSRC boleh merealisasikan susunan stesen pangkalan yang cekap dalam infrastruktur rangkaian ITS dan menyumbang kepada penggunaan ITS yang unggul.

Abstract: A number of mobile hosts might be densely staying in an area caused by traffic congestions. The greater part of the mobile hosts will require commonly useful data, such as traffic information, parking information and other driving related information in such environment. Simultaneous data transmission broadcasts using a common link are regarded as a suitable means to distribute this location-dependent information. However, there is no guarantee that mobile hosts can finish receiving the information completely within a limited time. In this paper, we propose a data retransmission method for communications between a base station and mobile hosts and a data recovery processing method for use between base stations. The data retransmission method called "TOA" (The Order of Arrival) schedules retransmission data specified in the first NACK request received after retransmission processing. We have proposed "Advanced" Join system in which a base station makes consolidated join requests to a multicast group on behalf of mobile hosts. Applying the TOA method to resending in the Advanced Join system, data-receiving efficiency is higher than with the simple Advanced Join system and the absolute number of completed mobile host data reception is higher. Using the TOA method, even with the base station disposition rate of 50% the number of completed reception is higher than with the Advanced Join system at 80%. The proposed reliable multicasting system to the DSRC-based ITS network can realize an efficient base station arrangement in the ITS network infrastructure and contribute to the deployment of a superior ITS.
