层次分析法在ZigBee网络语音通信中的应用研究

在自组织网络语音通信中,针对音频传输中存在的延时、丢包等主要问题,在ZigBee网络路由的基础上建立层次分析法评价模型,设计了一种音频传输路由算法AHP-RP。通过分析路径链路质量、音频负载值、路径存活时间和路径长度等因素对音频质量的影响,构建以网络的4个因素为因子的比较矩阵,选择最优传输路径。仿真及实际通信平台验证表明,该算法能有效地适应网络状态,明显改善了语音通话质量。

Application of AHP in ZigBee Network Voice Communication

Aiming at the main problems of voice communication in the audio transmission of Ad Hoc network, such as delay, packet loss and so on, AHP(Analytic Hierarchy Process) evaluation model based on the ZigBee network routing is established,and a routing algorithm, AHP-RP for audio transmission is designed. By analyzing the influence of path link quality, audio load value,path survival time, path length and other factors on quality of the audio, the four-factor comparison matrix of network based on selection of the optimal transmission path is constructed. Simulation and actual communication platform validation indicate that the proposed algorithm can effectively adapt to the network status, significantly improve the quality of voice communication.
