Many industrial automation solutions use wireless communication and rely on the availability and quality of the wireless channel. At the same time the wireless medium is highly congested and guaranteeing the availability of wireless channels is becoming increasingly difficult. In this work we show, that ad-hoc networking solutions can be used to provide new communication channels and improve the performance of mobile automation systems. These ad-hoc networking solutions describe different communication strategies, but avoid relying on network infrastructure by utilizing the Peer-toPeer (P2P) channel between communicating entities. This work is a step towards the effective implementation of low-range communication technologies (e.g. Visible Light Communication (VLC), radar communication, mmWave communication) to the industrial application. Implementing infrastructure networks with these technologies is unrealistic, since the low communication range would necessitate a high number of Access Points (APs) to yield full coverage. However, ad-hoc networks do not require any network infrastructure. In this work different ad-hoc networking solutions for the industrial use case are presented and tools and models for their examination are proposed.The main use case investigated in this work are Automated Guided Vehicles (AGVs) for industrial applications. These mobile devices drive throughout the factory transporting crates, goods or tools or assisting workers. In most implementations they must exchange data with a Central Control Unit (CCU) and between one another. Predicting if a certain communication technology is suitable for an application is very challenging since the applications and the resulting requirements are very heterogeneous. The proposed models and simulation tools enable the simulation of the complex interaction of mobile robotic clients and a wireless communication network. The goal is to predict the characteristics of a networked AGV fleet.The proposed tools were used to implement, test and examine different ad-hoc networking solutions for industrial applications using AGVs. These communication solutions handle time-critical and delay-tolerant communication. Additionally a control method for the AGVs is proposed, which optimizes the communication and in turn increases the transport performance of the AGV fleet. Therefore, this work provides not only tools for the further research of industrial ad-hoc system, but also first implementations of ad-hoc systems which address many of the most pressing issues in industrial applications.

520 $a Viele industrielle Automatisierungslosungen verwenden drahtlose Kommunikationssysteme und sind daher auf die Verfugbarkeit und Qualitat des drahtlosen Kanals angewiesen. Gleichzeitig ist das drahtlose Medium stark belastet und die Gewahrleistung der Verfugbarkeit der drahtlosen Kanale wird zunehmends herrausfordernder. In dieser Arbeit wird gezeigt, dass Ad-hoc-Netzwerklosungen genutzt werden konnen, um neue Kommunikationskanale bereitzustellen und die Leistung von mobilen Automatisierungssystemen zu verbessern. Diese Ad-hoc-Netzwerklosungen konnen unterschiedliche Kommunikationsstrategien bezeichnen. In all diesen Strategien wird der Peer-to-Peer (P2P)-Kanal zwischen zwei kommunizierenden Systemen verwendet statt Netzwerk-Infrastruktur.Diese Arbeit ist ein Schritt hin zur effektiven Implementierung von Kommunikationstechnologien mit geringer Reichweite (z.B. Visible Light Communication (VLC), Radarkommunikation, mmWave-Kommunikation) in der industriellen Anwendung. Die Implementierung von Infrastrukturnetzen mit diesen Technologien ist unrealistisch, da die geringe Kommunikationsreichweite eine hohe Anzahl von Access Points (APs) erfordern wurde um eine flachendeckende Bereitstellung von Kommunikationskanalen zu gewahrleisten. Ad-hoc-Netzwerke hingegen benotigen keine Netzwerkinfrastruktur. In dieser Arbeit werden verschiedene Ad-hoc-Netzwerklosungen fur den industriellen Anwendungsfall vorgestellt und Werkzeuge und Modelle fur deren Untersuchung vorgeschlagen.Der Hauptanwendungsfall, der in dieser Arbeit untersucht wird, sind Fahrerlose TransportSysteme (FTS) (fortfuhrend als Automated Guided Vehicles (AGVs)) fur industrielle Anwendungen. Diese FTS fahren durch die Produktionsanlage um Kisten, Waren oder Werkzeuge zu transportieren oder um Mitarbeitern zu assistieren. In den meisten Implementierungen mussen sie Daten mit einer Central Control Unit (CCU) und untereinander austauschen. Die Vorhersage, ob eine bestimmte Kommunikationstechnologie fur eine Anwendung geeignet ist, ist sehr anspruchsvoll, da sowohl Anwendungen als auch Anforderungen sehr heterogen sind.Die prasentierten Modelle und Simulationswerkzeuge ermoglichen die Simulation der komplexen Interaktion von mobilen Robotern und drahtlosen Kommunikationsnetzwerken. Das Ziel ist die Vorhersage der Eigenschaften einer vernetzten FTS-Flotte. Mit den vorgestellten Werkzeugen wurden verschiedene Ad-hoc-Netzwerklosungen fur industrielle Anwendungen mit FTS implementiert, getestet und untersucht. Diese Kommunikationssysteme ubertragen zeitkritische und verzogerungstolerante Nachrichten. Zusatzlich wird eine Steuerungsmethode fur die FTS vorgeschlagen, die die Kommunikation optimiert und damit einhergehend die Transportleistung der FTS-Flotte erhoht. Dieses Werk fuhrt also nicht nur neue Werkzeuge ein um die Entwicklung industrieller Ad-hoc Systeme zu ermoglichen, sondern schlagt auch einige Systeme fur die kritischsten Kommunikationsprobleme industrieller Anwendungen vor.
