M-DCF:在单区网中实现QoS的媒体访问协议

M DCF:a MAC protocol implementing QoS in Ad Hoc network

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。

M DCF is proposed based on the characteristic of IP packet network,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
