Abstract

In this paper, we propose stabilized MAC protocol to resolve the bistable problem of the slotted ALOHA. The proposed protocol controls the random access rates according to the characteristics of traffic classes. The mathematical model and the experimental results show that the proposed protocol can guarantee the stable operation of random access procedure.

본 논문에서는 경쟁채널에서 시스템 부하가 큰 경우 수율이 불안정해지는 slotted ALOHA의 문제점을 해결하기 위해 실시간 및 비실시간 서비스 클래스의 특성을 기준으로 액세스 패킷 전송률을 조절하는 안정화된 매체접근제어 프로토콜을 제안한다. 수학적 모델 및 시뮬레이션 결과는 제안하는 프로토콜이 랜덤 액세스 절차에서의 안정적인 수율을 보장함을 보인다.
