随着无线Mesh网络应用的日益广泛,无线Mesh网络的服务提供和性能保证逐渐成为研究者和使用者关心的主题,本文根据无线Mesh网络中流量的到达具有自相似特性,基于当前流行的随机网络演算提出具有分形布朗运动的自相似到达流的无线Mesh网络流量模型.利用中心极限定理构造聚合流和单流的随机到达曲线.数值结果表明本文提出的流量模型能反映出无线Mesh网络流量的实际特征.本文结论在基于随机网络演算的高质量、高可靠性的无线Mesh网络服务质量保证研究中具有重要的理论价值,对无线Mesh网络的性能评价具有重要意义.
With the increasing popularity of wireless Mesh networks, the service provision and performance guarantee of Wireless Mesh Networks (WMN) have gradually become the topics of interest to researchers and users. Based on the self-similar characteristics of the arrival of wireless Mesh networks, based on the currently popular random networks The proposed wireless Mesh network traffic model with self-similar arrival flow of fractal Brownian motion is proposed.The center-bound theorem is used to construct the random arrival curve of aggregate flow and single flow.The numerical results show that the proposed traffic model can reflect the actual flow of wireless Mesh network Features.The conclusion of this paper is of great theoretical value in the research of QoS guarantee of high quality and reliability wireless mesh networks based on stochastic network calculus, which is of great significance for the performance evaluation of wireless Mesh networks.
