移动机器人TSCH网络的主动连接基础

Active Connectivity Fundamentals for TSCH Networks of Mobile Robots

Charalampos Orfanidis, Paul Pop, Xenofon Fafoutis

摘要:

时隙信道跳变(TSCH)是IEEE 802.15.4标准中定义的介质访问协议,其已被证明是工业应用中最可靠的选择之一。TSCH被设计用于静态网络拓扑。因此,如果应用场景需要移动网络拓扑,则TSCH不能可靠地执行。在本文中,我们介绍了主动连接的移动应用场景,如移动机器人。这是一个功能,使选项能够调节物理特性,如节点移动时的速度,以便保持连接到TSCH网络。我们通过一个基本的例子,其中两个节点正朝着同一方向移动,推断所介绍的方法的主要原则,主动连接的方法建模。我们通过模拟评估主动连接功能,并量化连接和应用层性能之间的权衡。

英文摘要:

Time Slotted Channel Hopping (TSCH) is a medium access protocol defined in the IEEE 802.15.4 standard which have been proven to be one of the most reliable options when it comes to industrial applications. TSCH has been designed to be utilized in static network topologies. Thus, if an application scenario requires a mobile network topology, TSCH does not perform reliably. In this paper we introduce active connectivity for mobile application scenarios, such as mobile robots. This is a feature that enables the option to regulate physical characteristics such as the speed of a node as it moves, in order to keep being connected to the TSCH network. We model the active connectivity approach through a basic example where two nodes are moving towards the same direction to infer the main principles of the introduced approach. We evaluate the active connectivity feature through simulations and quantify trade-off between connectivity and application-layer performance.
