Abstract
A wireless bridge is essential to transmit control and managing information to sensors or instruments from a central integrated ship area network station. In this paper, a WiMedia Distributed-MAC(D-MAC) protocol is adopted for development of a seamless N-Screen wireless service in Indoor and Ship Area Networks. Furthermore, to provide the OSMU(One Source Multi Use) N-screen service through P2P streaming in the seamless D-MAC protocol, a Dynamic Threshold-based Multicast(DTM) technology is proposed and analyzed. For this technology, a new Hard/Soft Vertical Region(HVR-SVR) based time slot allocation and a multicast resource reservation scheme are combined. From simulation results, proposed DTM scheme expands the number of time slots available for unicast and multicast realtime N-Screen reservations with various service time interval requests. Furthermore, it enhances performances in vewpoints of realtime N-Screen data reservation conflict and throughput. 논문 15-40-07-18 The Journal of Korean Institute of Communications and Information Sciences '15-07 Vol.40 No.07 http://dx.doi.org/10.7840/kics.2015.40.7.1369 1369 ※ 본 논문은 2014년도 정부(교육부)의 재원으로 한국연구재단의 지원을 받아 수행된 기초연구사업의 결과임(NRF-2014R1A1A205362 1) 및 2014년도 정부(교육부)의 재원으로 한국연구재단의 지원을 받아 수행된 기초연구사업(NRF-2009-0093828)과 미래창조과학부 및 정보통신기술진흥센터의 ICT 융합고급인력 과정지원사업(IITP-2015-H8601-15-1006)의 연구결과로 수행되었음 First Author : Gyeongin National University of Education Department of Computer Education, khur@ginue.ac.kr, 종신회원 ° Corresponding Author : Mokpo National University Department of Electronics Engineering, srlee@mokpo.ac.kr, 정회원 논문번호:KICS2015-04-104, Received April 2, 2015; Revised July 9, 2015; Accepted July 9, 2015 The Journal of Korean Institute of Communications and Information Sciences '15-07 Vol.40 No.07
