Real-Time Transmission Scheme for Ad Hoc Self-Organizing (ASO) TDMA in Multi-Hop Maritime Communication Network

In this paper, we first analyze the delay performance of Dynamic Space-time Subframe (DSTS)-based frame structure which has been proposed to support the real-time service as well as non real-time service, using Ad hoc Self-Organizing Time Division Multiple Access (ASO-TDMA) MAC protocol, especially when transmitting a MAC SDU with two or more MAC PDUs, in a multi-hop ad-hoc maritime communication network. We propose two key transmission schemes: contiguous DSTS reservation which guarantees the end-to-end delay for the multiple PDUs, and adaptive transmission probability control schemes to maximize the system throughput. Our simulation results show that the proposed schemes outperform the system throughput of the existing transmission schemes, while supporting the real-time requirement. 논문 14-39B-05-02 The Journal of Korea Information and Communications Society '14-05 Vol.39B No.05 http://dx.doi.org/10.7840/kics.2014.39B.5.260 260 ※ 본 연구결과는 국토해양부의 “U기반 해운 물류 체계 구축을 위한 기반기술 연구” 과제에서 수행된 연구결과 중 일부임을 밝히며, 연구비 지원에 감사드립니다. ° First Author and Corresponding Author : Korea University School of Electrical Engineering, kumin84@korea.ac.kr, 학생회원 * 한국해양과학기술원, {sgn0178, yklim}@kiost.ac, 정회원 ** 고려대학교 전기전자전파공학부, ccgkang@korea.ac.kr, 종신회원 논문번호:KICS2014-04-110, Received April 1, 2014; Revised April 21, 2014; Accepted May 12, 2014 논문 / Ad Hoc Self-Organizing (ASO) TDMA 방식 다중-홉 해양통신망에서의 실시간 전송 기법
