Abstract

In this paper, WiMedia Distributed-MAC protocol is adopted for development of an OSMU (One Source Multi Use) N-screen wireless multicast service. But, when considering wireless communication environment where channel error rate is time-variant, N-screen high-speed data is vulnerable to be lost. For this problem, a multicast relay scheme is proposed by analyzing Distributed-MAC protocol. In proposed multicast relay scheme, Multicast-free DRP Availability IE is combined and the relay node suitable for N-screen multicast transmissions is selected. Through this operation, it can avoid wireless channel with high errors and can transmit N-screen high-speed data. In simulation results, the proposed multicast relay scheme is compared with conventional Distributed-MAC multicast scheme in view points of throughput and energy consumption according to various numbers of multicast nodes and BER (Bit Error Rate) values in wireless channel. Through simulation results, it is explained that proposed multicast relay scheme should be adopted in WiMedia Distributed-MAC protocol to realize OSMU N-screen wireless multicast services.

본 논문에서는 OSMU (One Source Multi Use) N-스크린 멀티캐스트 서비스를 위한 무선 통신 MAC 구조로서, WiMedia Distributed-MAC 프로토콜을 적용하였다. 그러나, 채널 에러율이 가변적인 무선 통신환경을 고려하면, N-스크린 고속 데이터가 손실될 가능성이 높다고 할 수 있다. 이러한 문제에 대해, WiMedia Distributed-MAC 프로토콜을 분석하여, 멀티캐스트 릴레이 기술을 제안하였다. 제안하는 멀티캐스트 릴레이 기술은 Multicast-free DRP Availability IE 기술과 결합되어, 멀티캐스트 통신에 대해 릴레이노드를 선정하고 에러율이 높은 채널을 회피하여 통신할 수 있다. 시뮬레이션을 통해 제안하는 멀티캐스트 릴레이 기술과 기존 WiMedia Distributed-MAC 멀티캐스트 기술을 멀티캐스트 노드 수에 따라 수율과 에너지 소모량을 비교 하였고, 다양한 BER (Bit Error Rate) 채널 환경에서 수율 성능을 비교하였다. 이를 통해, OSMU N-스크린 멀티캐스트 서비스에서 멀티캐스트 릴레이 기술이 적용되어야 함을 설명하였다.
