论文摘要
时间开槽的频道跳跃（TSCH）是IEEE 802.15.4标准中定义的中型访问协议，在工业应用方面已被证明是最可靠的选择之一。 TSCH已设计为用于静态网络拓扑中。因此，如果应用程序方案需要移动网络拓扑，则TSCH不会可靠地执行。在本文中，我们为移动应用程序方案（例如移动机器人）介绍了主动连接性。这是一项功能，它使选项可以调节物理特性，例如节点移动时的速度，以便继续连接到TSCH网络。我们通过一个基本示例对主动连接方法进行建模，其中两个节点朝着相同方向移动，以推断引入方法的主要原理。我们通过模拟评估主动连接功能，并量化连接性和应用程序层性能之间的权衡。
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.
