Abstract

The IEEE 802.11 based wireless local area networks are candidates to lead the broadband connectivity in the home and office scenarios. Recently IEEE proposed the 802.11e as a new standard to provide appropriate Quality of Services to a plethora of emerging real-time multimedia and high demanding applications such as high definition movie and audio distribution, video-conference and voice over IP. This paper studies the IEEE 802.11e/IEEE 802.11b interactions focusing on potential unfairness problems that might appear in networks with heterogeneous wireless LAN technologies as well as in the IEEE 802.11e deployment phase.

IEEE 802.11기반 무선 랜은 가정과 사무실 환경에서 무선 연결 서비스를 제공하는 대표적인 기술이다. 최근 들어 HDTV나 화상회의 또는 VoIP와 같은 실시간 멀티미디어 서비스들에 대한 요구가 증가함에 따라 이를 뒷받침하기 위한 QoS (Quality of Service) 지원 메커니즘인 IEEE 802.11e가 제안되었다. 본 논문에서는 IEEE 802.11e 기술이 확산되면서 발생할 수 있는 IEEE 802.11e와 IEEE 802.11b 기술의 혼재 상황에서의 불공평 문제에 대하여 다룬다.
