Abstract

This paper proposes a discriminative collision resolution scheme for the wireless Medium Access Control (MAC) protocols to support the Quality of Service (QoS) requirements of real-time applications. Our scheme deals with access requests in different ways depending on their delay requirements. In our scheme, a Collision Resolution Period (CRP) is used to quickly resolve collisions for the delay sensitive traffic in order to support their delay requirements. Performance analysis and simulation results show that our algorithm may successfully meet the delay requirements of real time applications by reducing access delays and collisions.

본 논문에서는 무선 MAC 프로토콜상에서 실시간 응용의 QoS를 보장할 수 있는 지연 민감도를 고려한 차별적인 충돌해결 기법을 제안한다. 제안된 기법은 충돌해결을 위해 접근 요구 메시지들을 지연에 따라 서로 다르게 다루며, 이를 위해 본 논문에서는 지연 민감도가 높은 트래픽의 충돌해결을 보다 빠르게 해결하기 위해 CRP (Collision Resolution Period) 구간을 사용한다. 성능분석과 시뮬레이션 결과 제안된 프로토콜이 접근지연과 충돌의 정도를 줄임으로서 실시간 응용의 지연요구조건을 성공적으로 보장함을 보여준다
