论文摘要
本文的结果是有关移动药物多层网络中全球生存和灭绝的结果。在[CHJW22]中首先提出的模型上,我们考虑了一个城市环境,该环境由平面中的线条分析表示,在该环境中,代理根据基于Poisson点过程的随机路点模型移动。每当两个代理在足够长的时间内足够接近近距离时,就可以通过相同的规则从典型的设备开始传播感染,然后根据相同的规则传播到系统中。受到无线网络体系结构的启发,该网络还配备了第二类代理,该代理能够将补丁传输到相邻的受感染剂,进而可以进一步分发贴片,从而导致Chase-escape Dynamics。我们为参数配置提供了条件,这些条件取决于设备的速度,可以保证和不存在全局生存以及生存方案的范围。我们还为Chase-Escape动力学定义为连接图上的独立过程的设置提供了互补的结果。这些证明主要取决于通过离散化和多尺度分析的渗透论证。
The present paper features results on global survival and extinction of an infection in a multi-layer network of mobile agents. Expanding on a model first presented in [CHJW22], we consider an urban environment, represented by line-segments in the plane, in which agents move according to a random waypoint model based on a Poisson point process. Whenever two agents are at sufficiently close proximity for a sufficiently long time the infection can be transmitted and then propagates into the system according to the same rule starting from a typical device. Inspired by wireless network architectures, the network is additionally equipped with a second class of agents that is able to transmit a patch to neighboring infected agents that in turn can further distribute the patch, leading to a chase-escape dynamics. We give conditions for parameter configurations that guarantee existence and absence of global survival as well as an in-and-out of the survival regime, depending on the speed of the devices. We also provide complementary results for the setting in which the chase-escape dynamics is defined as an independent process on the connectivity graph. The proofs mainly rest on percolation arguments via discretization and multiscale analysis.
