M-DCF：在单区网中实现QoS的媒体访问协议

摘要

M-DCF is proposed based on the characteristic of IP packetnetwork，which is apply to Ad Hocnetwork in WLAN.The computer simulation shows that M-DCF can decrease the system drop packet rate，voice service drop packet rate，voice packet contention latency，as well as data packet contention latency.%本文结合IP通信的特点，提出了一种适用于WLAN单区网的改进型媒体访问控制协议M-DCF，并进行了计算机仿真。仿真结果表明，M-DCF可以降低系统总的丢包率，话音业务的丢包率，降低话音帧的时延，从而保证话音业务的服务质量。同时也降低了数据帧的时延。
