Dynamic Random Geometric Graphs
摘要:
在这项工作中,我们引入动态随机几何图形作为移动无线传感器网络的基本粗糙模型,其中通信距离被设置为静态随机几何图形的连通性的已知阈值。我们提供精确的渐近结果的预期长度的连通性和不连通的网络期间。我们相信,在这项工作中开发的正式工具可以在更具体的设置在未来的研究中使用。此外,对于静态随机几何图在阈值的连通性,我们提供了渐近表达式的组件存在的概率,根据其大小。
英文摘要:
In this work we introduce Dynamic Random Geometric Graphs as a basic rough model for mobile wireless sensor networks, where communication distances are set to the known threshold for connectivity of static random geometric graphs. We provide precise asymptotic results for the expected length of the connectivity and disconnectivity periods of the network. We believe the formal tools developed in this work could be of use in future studies in more concrete settings. In addition, for static random geometric graphs at the threshold for connectivity, we provide asymptotic expressions on the probability of existence of components according to their sizes.
