Abstract

In this paper, we propose a transmission scheme of MAC protocol that enables secure voice communications by exploiting the wide spectrum and low signal strength characteristics of the ultra wide band technology. In addition, it also supports high level of terminal mobility by deploying mobile ad hoc network schemes. While most of existing UWB MAC protocols are operated as a synchronous mode, the proposed scheme operates in an asynchronous mode for supporting high mobility and sends voice packets without RTS/CTS control packets for efficient voice traffic transmission without retransmission. With simulation program, we prove that the proposed scheme satisfies the required voice quality and packet delivery time.

본 논문에서는 UWB의 광대역 주파수와 낮은 신호세기의 특성을 이용해서 기밀한 음성 통신이 가능하고, 이동 ad hoc 네트워크로 동작하도록 하여 단말의 이동이 가능한 전술망용 MAC 프로토콜의 효과적인 음성 데이터 전송 기법을 제안하였다. 기존의 UWB MAC 프로토콜은 대부분 단말 간 동기화를 지원하여 전력 소모, 대역폭과 같은 자원 활용에 중점을 두었으나, 본 논문의 UWB MAC 프로토콜은 단말의 이동성에 중점을 두어 비동기 방식으로 구동된다. 또한 효과적인 음성 데이터 전송을 위해서 RTS/CTS 패킷을 사용하지 않고, 재전송 과정이 없다. 해당 음성 데이터 전송 방식의 시뮬레이션을 통하여 성능을 측정하였다.
