具有相关阴影的室内无线网络三维空间模型

Junse Lee, Xinchen Zhang, Francois Baccelli

摘要:

考虑三维空间中的正交平面,表示大型建筑物中的地板和墙壁。这些平面将空间划分为部署无线基础设施的房间。本文的重点是通过一组墙壁和地板的无线基础设施创建的相关阴影场的分析。当飞机和无线节点的位置是由泊松过程,我们得到一个简单的随机模型,捕捉节点部署和房间大小的非均匀性。这个模型,我们建议称之为泊松建设,捕捉复杂的建筑物内阴影的相关性,是可扩展的维度的数量,是易于处理的网络性能分析。它允许在无限和有限建筑物中的干扰分布的精确数学表征,这进一步导致建筑物内蜂窝网络中的覆盖概率和建筑物内CD2D传输的成功概率的封闭形式的表达式。

英文摘要:

Consider orthogonal planes in the 3-D space representing floors and walls in a large building. These planes divide the space into rooms where a wireless infrastructure is deployed. This paper is focused on the analysis of the correlated shadowing field created by this wireless infrastructure through the set of walls and floors. When the locations of the planes and of the wireless nodes are governed by Poisson processes, we obtain a simple stochastic model which captures the non-uniform nature of node deployment and room sizes. This model, which we propose to call the Poisson building, captures the complex in-building shadowing correlations, is scalable in the number of dimensions and is tractable for network performance analysis. It allows an exact mathematical characterization of the interference distribution in both infinite and finite buildings, which further leads to closed-form expressions for the coverage probabilities in in-building cellular networks and the success probability of in-building underlay D2D transmissions.
