VoIP(Voice over IP)는 무선 LAN 시스템이 일반적으로 지연 시간, 지터 및 패킷 손실과 관련된 엄격한 품질 요구 사항을 충족하도록 요구하는 실시간 애플리케이션 중 하나입니다. 그러나 음성과 데이터 트래픽이 공존하는 경우 CSMA/CA(Carrier Sense Multiple Access with Collision 회피)는 VoIP가 요구하는 서비스 품질을 달성하기 어렵기 때문에 일종의 우선순위 제어가 필요합니다. 본 논문에서는 무선랜이 VoIP 요구사항을 만족시킬 수 있는 자율분산제어 기반의 새로운 다중접속 프로토콜을 제안한다. 이 새로운 프로토콜은 VoIP와 데이터 트래픽 모두에 적합하며 VoIP 패킷이 데이터 패킷 또는 다른 VoIP 패킷과 충돌하는지 여부에 따라 동적으로 우선 순위 제어를 실행합니다. 이론적인 분석과 컴퓨터 시뮬레이션 결과, 우수한 성능을 보여줍니다. 본 제안 프로토콜은 패킷 손실 확률이 54% 미만이면 트래픽 부하가 증가하더라도 기존 CSMA/CA에 비해 VoIP 패킷의 지연 시간을 70~3% 감소시킨다.

Abstract: VoIP (Voice over IP) is one of the real time applications that demand wireless LAN systems meet severe quality requirements which commonly involve delay time, jitter, and packet loss. However, it is difficult for CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to achieve the service quality demanded by VoIP if voice and data traffic coexist, so some form of priority control is needed. This paper proposes a novel multiple access protocol based on autonomous distributed control that allows wireless LANs to satisfy the VoIP requirements. This new protocol suits both VoIP and data traffic and executes priority control dynamically according to whether the VoIP packet collides with a data packet or another VoIP packet. The results of a theoretical analysis and computer simulations indicate its excellent performance. This proposed protocol reduces the delay time of VoIP packets by 54 to 70% compared with conventional CSMA/CA even if the traffic load increases provided that the packet loss probability is less than 3%.
