活跃节点相关性考虑下的多跳无线网络性能分析

摘要

In recent years , classical information theory and Queuing theory have been successfully studying point-to-multipoint links in wireless network .However , they are not enough to characterize the intricacies of multihop wireless networks(MHWN) for inherent interactions between nodes .In this paper, we focus on the modeling and analysis of multihop wireless networks .To make the model present strong correlations inter-de-pendencies between the active nodes in MHWN , we use exiting theory from stochastic geometry and statistical physics to analyze performance for MHWN .Numerical results show that our model can allow a clean , yet ac-curate analysis , and provide scalability with nodes in the network .%对于无线网络性能分析的研究多是采取信息论和排队论的方法，这些方法虽然可以较好得对点到多点的无线网络进行建模分析，但是对于多跳无线网络（ MHWN ），由于其固有的分布式及相关性特点，已有方法存在建模复杂和可扩展性差等问题。为了更好的反映多跳网络中的活跃节点相关性特点，提出了一种结合随机几何理论和统计物理学理论的分析方法。数值分析结果表明，本文的模型不仅易于建模和分析，也更加准确和具有可扩展性。
