【摘要】 针对速率信息的交换、预约时长设置以及相关网络分配矢量的更新和计算,基于碰撞检测的载波侦听多址协议,提出了一种交换速率信息的多速率传输协议RIEMS协议.基于802.11a协议中DCF方式来实现无线局域网RIEMS协议多速率传输的模型,分析得到了影响多速率传输协议性能的参数,完成该模型的仿真.仿真结果表明多速率传输可以大幅度提高网络性能.此模型可以应用于支持非对称信道、ad_hoc网络、高速移动、速率可变宽带无线移动网络的媒体接入控制.更多还原

【Abstract】 For rate information,duration and network allocation vector,the rate information exchanging multispeed supported(RIEMS) protocol is suggested based on CSMA.The model of RIEMS protocol is realized by DCF based on 802.11.The parameters of function are analysed,and simulation of this system is completed.The function of network can be raised greatly by multispeed transmission.This research result can be used in media insert control of WLAN of HV transmission and variable speed,dissymmetric channel and ad_hoc network.更多还原
