摘要
通过探讨G.107标准的E模型,结合IETF工作组制定的无线Ad Hoc网性能评价参数,提出一种基于E扩展模型的语音通信性能评价模型,将网络性能评价与传统的主观MOS评判法进行参数映射,从而获得一种Ad Hoc网语音通信Qo S性能评价方法。该方法不仅可以通过外部主动探测获得网络通信性能,还可用作网络内部链路质量衡量,为路由优化提供参考。
The paper discusses the E model of G.107 standard and proposes a voice communication performance evaluation model based on the E extension model combining the performance evaluation parameters of wireless Ad Hoc network formulated by the IETF working group. The network performance evaluation is mapped with the traditional subjective MOS evaluation,and thus a voice communication performance evaluation method for Ad Hoc networks is achieved. This method not only obtains the network communication performance through external active detection,but also is used as a measure of the network internal link quality,providing a reference for the route optimization.
