Dependable communication for mobile robots in industrialwireless mesh networks
In: Cooperative Robots and Sensor Networks 2015. - Cham [u.a.] : Springer International Publ., S. 207-227 - (Studies in Computational Intelligence; 604) ; ISBN: 978-3-319-18299-5 DOI: 10.1007/978-3-319-18299-5_10
http://www.springerprofessional.de/010---dependable-communication-for-mobile-robots-in-industrial-wireless-mesh-networks/5739414.html
Mobile robots inevitably require a wireless network for communication. Wireless mesh networks (WMNs) allow for increased flexibility and an easy integration of mobile robots. Hence, they are well suited for present and future cyber-physical industrial applications. The high dependability requirements of that application domain, however, issue particular challenges to the communication network, especially regarding the mobility of stations. In this chapter, we present various approaches and mechanisms to provide dependable communication for mobile robots in industrial WMNs. These comprise different cross-layer techniques to allow for seamless mobility and an admission control that explicitly considers station mobility to avoid network overload. Evaluation results are gathered by both simulation and real-world experiments while case-studies supplement the results. The outcome is a network architecture that allows for seamless communication even for mission-critical applications on mobile robots.

Dependable Admission Control for Mission-Critical Mobile Applications in Wireless Mesh Networks
Proceedings of the 33rd IEEE Symposium on Reliable Distributed Systems
Wireless Mesh Networks (WMNs) provide a promising foundation for a flexible
and reliable communication infrastructure in industrial environments. Meeting
the QoS demands of industrial applications, though, requires the deployment of
an admission control to avoid network overload. The presence of mobile
stations, however, causes dynamics within the network that severely impacts
the available capacity. For instance, if a communication route switches from
one to two hops, twice the resources are consumed due to self-interference. To
neither jeopardize QoS guarantees nor having to cancel present flows, our
dependable admission control scheme foresees and considers those dynamics
during resource reservation to handle station mobility.
We describe a highly dependable approach and further propose an estimation
method that improves network efficiency. The evaluation results show that our
novel approach allows for a dependable admission control even in presence of
mobile stations and thus enables the network to provide a new class of
guarantee for mission-critical mobile applications.

Uniform Approach of Risk Communication in Distributed IT Environments Combining Safety and Security Aspects
Kongressband, Computer Safety, Reliability, and Security - SAFECOMP 2014 Workshop-Proceedings, s. 298-300, September 8-12, 2014, Florence, Italy
The trend to compose real time systems with standard IT known from conventional office domains results in heterogeneous technical environments. Examples are modern industrial process automation networks. It is a challenging task, because of potential impacts of security incidents to the system safety. For example, robot control units could be manipulated by malicious codes. The term “risk communication” is introduced, to describe alarm communication in human-machine
interaction scenarios. User adapted risk communication between humans and industrial automation systems, including home robotics, can prevent hazards and/or threats to the entire system safety and security. Current safety and security risk communication standards are compared to examine the adequacy for our uniform approach. This paper focuses on alarm
system standards in the industrial process automation domain and intrusion detection systems from the conventional desktop IT domain. A uniform model based approach for risk communication in distributed IT environments is introduced.

Towards an Isochronous Wireless Communication System for Industrial Automation
18th IEEE International Conference on Emerging Technologies and Factory Automation, September 10-13, 2013 Cagliary, Italy
Deploying wireless technologies in industrial automation becomes more and more common. It is an enabler for many innovative applications where moving system components are involved, e. g. rotating parts of machines. However, many of such applications impose high temporal requirements on the wireless system, for instance isochronous data communication. Today, these requirements can not be met by existing solutions, such as IEEE 802.11 Wireless Local Area Networks (WLANs). In this paper, an isochronous wireless communication system is investigated. It mainly consists of a deterministic medium access control, based on IEEE 802.11, which is extended with additional features for isochronous communication. The presented preliminary analysis shows the system’s feasibility for the targeted industrial applications and presents promising performance improvements in comparison with standard mechanisms.

Wireless Mesh Network Infrastructure for Industrial Applications - A Case Study of Tele-operated Mobile Robots
18th IEEE International Conference on Emerging Technologies and Factory Automation, September 10-13, 2013 Cagliary, Italy
The deployment of wireless communication networks in industrial facilities allows for increased flexibility and seamless integration of mobile participants. Time-critical control applications are generally realized with dedicated wireless sensor networks while common WLAN infrastructure networks allow high-throughput best-effort communication. To provide high-capacity communication as well as real-time service quality, we developed and implemented a Wireless Mesh Network (WMN) infrastructure for industrial applications. An example application that requires these properties is the video-based tele-operation of a mobile robot, which we present as case study in this work. It shows the applicability of our infrastructure as well as the necessity of its comprised components.

Tolerating Packet Losses in Wireless Mesh Networks
2013 IEEE 27th International Symposium on Parallel & Distributed Processing Workshops and PhD Forum, 20-24 May 2013, Boston (MA) USA
Wireless Mesh Networks (WMNs) provide a promising foundation for a flexible and reliable communication infrastructure in industrial environments. Meeting the QoS demands of real-time applications, though, requires the deployment of various advanced mechanisms. Compared to wired networks, applications face higher packet loss rates in wireless networks due to the inherent unreliability of wireless communication. Furthermore, if mobile stations are involved, links that fail due to node movement frequently cause packet losses. In this paper, we present an approach to tolerate those specific losses by locally recovering lost packets and transiently re-routing them over an alternative path. The evaluation in real-world experiments shows that we can completely prevent packet loss without significantly increasing the end-to-end latency. This allows the deployment of WMNs for real-time applications without explicitly considering the increased error-proneness of wireless communication and station mobility.

Data-mining-based Link Failure Detection for Wireless Mesh Networks
In Proceedings of the 29th IEEE International Symposium on Reliable Distributed Systems, 31 October - 4 November, 2010, New Delhi, India
Mobile robot applications operating in wireless environments require fast detection of link failures in order to enable fast repair. In previous work, we have shown that cross-layer failure detection can reduce failure detection latency significantly. In particular, we monitor the behavior of the WLAN MAC layer to predict failures on the link layer. In this paper, we investigate data mining techniques to determine which parameters, i.e., the events, or combination and timing of events, occurring on the MAC layer most probably lead to link failures. Our results show, that the parameters revealed with the data mining approach produce similar or even more accurate failure predictions than achieved so far.

Modeling Fast Link Failure Detection for Dependable Wireless Mesh Networks
In Proceedings of the 9th IEEE International Symposium on Network Computing and Applications, 15 - 17 July, 2010, Cambridge, MA, USA
Wireless Mesh Networks (WMN) provide a flexible and inexpensive way to expand network applications to mobile entities. However, high communication reliability demands can not be met by regular WMNs due to mobility and inherent properties of wireless communication. Failing links are common events which impose a major challenge for providing a dependable communication service. By the use of suitable cross-layer models, we provide a timely detection of failed links without compromising the network stability. It is shown that the packet loss caused by a link failure can be reduced from a time-dependent value to at most four consecutive packets. For a typical control application this means an improvement by a factor of 100. In addition to an empirical evaluation we demonstrate the applicability of the mechanism by utilizing it in a real-world WMN to allow the tele-operation of a mobile robot.

Dependable Wireless Mesh Networks: An integrated approach
International Journal of parallel, Emergent and Distributed Systems, April 2, 2009
Volume 24, Issue 2 April 2009, pages 151-169
Wireless Mesh Networks (WMNs) are gaining popularity in many application areas because of their low cost and high flexibility. Technically, a WMN forms a distributed network-centric system which aims to provide communication services to the application layer, but has no built-in dependability provisions. To make the network dependable, many problems have to be solved on different layers. With this paper, we describe our ongoing work to provide an integrated solution to increase the dependability of WMNs. Our approach combines network coverage planning on the physical layer, bandwidth management on the link layer and live network monitoring to improve the reliability, availability and maintainability of a WMN. We provide fine-grained means to improve the predictability of the network components, thus making the WMN more dependable. In this paper, we present first results of our work, and describe how they are interleaved.
