본 논문에서는 가입자망의 고속화를 실현하는 방안으로 개발되고 있는 B-WLL 시스템의 MAC 프로토콜을 설계하고 검증하였다. MAC 프로토콜의 설계는 DAVIC에서 제시하는 MAC 메시지를 사용하여 SDL로 설계했으며, 동적인 경쟁/예약 타임 슬롯할당 알고리즘을 적용했다. 또한 설계한 MAC 프로토콜의 유효성을 검증하기 위하여 ObjectGeode의 Simulation Builder를 이용하여 문법적인 오류를 검사하고, MSC(Message Sequence Chart)를 생성하여 프로토콜의 동작절차에 대해 검증하였다. 검증의 결과, 설계한 MAC 프로토콜이 절차에 따라 정확하게 동작했으며, B-WLL 시스템이 지원하는 모든 서비스에 대해 유효함을 확인했다.
