论文摘要

在本文中,我们考虑具有集成传感和通信功能的静态传感器网络。传感器的目的是将收集的信息传播给网络中的每个其他代理商以及可能是人类操作员。这样的任务需要在所有代理之间进行持续的通信,这可能会导致无线通信的碰撞和交通拥堵。为了减轻此问题,我们施加了本地非互助连接约束,每个代理必须尊重这些约束。我们表明,这些约束以及在网络中传播信息的要求可以通过线性时间逻辑(LTL)框架捕获。现有的时间逻辑控制合成算法可用于设计满足所考虑的LTL公式的正确构造通信时间表。然而,这种方法的集中式集中,并且随着网络规模的规模缩小。我们提出了一种基于层次LTL的算法,该算法设计了确定哪些代理在最大化网络使用时应通信的通信时间表。我们表明,所提出的算法是完整的,并通过分析和数值实验证明了其效率和可伸缩性。

In this paper, we consider networks of static sensors with integrated sensing and communication capabilities. The goal of the sensors is to propagate their collected information to every other agent in the network and possibly a human operator. Such a task requires constant communication among all agents which may result in collisions and congestion in wireless communication. To mitigate this issue, we impose locally non-interfering connectivity constraints that must be respected by every agent. We show that these constraints along with the requirement of propagating information in the network can be captured by a Linear Temporal Logic (LTL) framework. Existing temporal logic control synthesis algorithms can be used to design correct-by-construction communication schedules that satisfy the considered LTL formula. Nevertheless, such approaches are centralized and scale poorly with the size of the network. We propose a hierarchical LTL-based algorithm that designs communication schedules that determine which agents should communicate while maximizing network usage. We show that the proposed algorithm is complete and demonstrate its efficiency and scalability through analysis and numerical experiments.
