Abstract and Figures

Redundancy techniques based on the combination of multiple diverse communication channels are an established countermeasure to improve performance characteristics of wireless communication systems. Besides parallel redundancy in the space and frequency domain, serial redundancy in the time domain can be utilized. It is known that the parallel approaches can significantly improve performance characteristics like jitter and reliability, when applied for wireless packet-based data transmission. In this work, an investigation on the performance impact of additional time diversity on top of the parallel redundancy approaches is performed. An OPNET simulation model is created and analysed for its performance characteristics.

Requirements and current solutions of wireless communication in industrial automation
Conference Paper
Full-text available
  • Jun 2014
The industrial wireless automation sector exhibits a huge market growth in the last years. Today, many appli-cations already use wireless technologies. However, the existing wireless solutions do not yet offer sufficient performance with respect to real-time and reliability requirements, particularly for closed-loop control applications. As a result, low latency wireless communication technologies will bridge the gap and can become a key factor for the wide-spread penetration of wireless in industrial communication systems. It is therefore the main goal of this paper to provide a comprehensive overview on requirements, current solutions, and challenges as well as opportunities for future wireless industrial systems. Thereby, presented requirement figures, analysis results, and performance evaluations are based on numerous practical examples from industry.

Experimental validation of the usability of Wi-Fi over redundant paths for streaming phasor data
Conference Paper
  • Nov 2016
Applications performing streaming of phasor-measurement data require low latency and losses from the communication network. Traditionally, such requirements are realized through wired infrastructure. Recently, wireless infrastructure has gained attention due to its low-cost and ease of deployment, but its poor quality-of-service is a strong deterrent for use in mission-critical applications. Recent studies have used measurements to explore the use of packet replication over redundant Wi-Fi paths, for obtaining the desired loss performance without hampering the end-to-end latency. However, these studies are done in a controlled, laboratory environment and do not reflect the real, in-field performance. In this paper, we perform extensive measurements using two co-located directional Wi-Fi links in a real-life setting, to experimentally validate the use of packet replication over Wi-Fi for streaming phasor data. In the setting that we evaluated, we find that the two channels are not fail-independent but the performance achieved with replication is very close to what it would be if they were to be independent. From the loss and latency statistics after replication, we conclude that replicating the phasor data over redundant Wi-Fi paths is a viable option for achieving the desired quality-of-service.

Towards a reliable parallel redundant WLAN black channel
Conference Paper
Full-text available
  • May 2012
WLAN according to standard IEEE 802.11 is widely regarded unsuitable as communication channel for real-time and safety applications. Non-determinism and interference liability leads to packet loss, exceeded and variable latency times due to retransmissions. This work proposes a method that compensates such consequences of stochastic channel fading by the parallel operation of diverse wireless channels, applying frequency and space diversity techniques. A fault-tolerant wireless “black channel” is achieved that is able to fulfill soft real-time availability plus providing redundancy. This is realized with standard WLAN components and the “Parallel Redundancy Protocol” (PRP) according to IEC 62439-3. Reliability and performance characteristics are derived from measurements on an experimental setup with SafetyNET p nodes.

GeoSwarm: A Multi-Source Download Scheme for Peer-to-Peer Location-based Services
Conference Paper
Full-text available
  • Sep 2013
Existing peer-to-peer (p2p) overlays for location-based services suffer from two major drawbacks: (i) they do not store data persistently under peer churn and (ii) they do not allow for the fast retrieval of large files, especially under asymmetric link conditions. This tremendously limits the use of current and future p2p location-based services as users are not able to share larger files such as high resolution pictures or video snippets. To overcome these two problems, we present GeoSwarm: a reliable multi-source download scheme for p2p location-based services. GeoSwarm combines the strengths of a BitTorrent-like download scheme with the locality awareness of an overlay for location-based search and its built-in replication mechanism. Thereby, a robust and fast download as well as a reliable storage of location-related multimedia content is achieved. Through extensive evaluation, we show that 95% of all downloads in GeoSwarm are carried out successfully even under churn, while downloads benefit from a 100% increased throughput in comparison to traditional single-source downloads.

IEC 62439 PRP: Bumpless recovery for highly available, hard real-time industrial networks
Conference Paper
Full-text available
  • Oct 2007
Availability of automation networks can be increased by providing redundant links and nodes. Although many specifications of industrial Ethernet have been submitted to the International Electrotechnical Committee (IEC), they do not disclose methods to implement network redundancy. The IEC SC65C worked out a standard for implementing redundancy in switched Ethernet networks applicable to a variety of industrial networks, with different solutions depending on the grace time of the plant and on the level of redundancy desired. This paper describes IEC 62439's parallel redundancy protocol (PRP), a redundancy method applicable to hard real time systems, based on full duplication and parallel operation of two redundant networks. PRP nodes send on both networks at the same time, and receive from both, providing bumpless recovery. Duplicate discarding and management functions complement the standard.

  • Aug 2011
Since P2P systems have become popular in the late nineties, simulation of these systems has always been a preferable method of performance evaluation. Simulations facilitate the development and evaluation of 'newprotocols and mechanisms, while enabling a comparison of existing solutions. In this paper, we present PeerfactSim.KOM, a discrete-event P2P simulator that is suitable for a wide range of varying scenarios in the area of P2P. It consists of a layered architecture, provides a broad selection of P2P protocols for the modeled layers, and eases the implementation of new components through its modular design. In addition, the simulator provides helpful tools to configure and evaluate a simulation scenario.

Sensor/Actuator mobility in noisy Wi-Fi based Networked Control System
Conference Paper
  • Feb 2013
The increase in the application of Wireless Networked Control Systems (WNCS) in industrial automation motivates the study of the effect of mobility of WNCS nodes in the presence of noise. A WNCS system should satisfy certain end-to-end delay constraints, with all types of propagation, queuing, encapsulation/decapsulation and processing delays. Also, no data packets should be lost. These requirements should be met in the existence of 2.4GHz Industrial, Scientific and Medical (ISM) band interference. In this paper, an enhanced WNCS system is studied based on previous publications using unmodified Wi-Fi and Ethernet. The system is modified to include Sensor/Actuator mobility. A comparison between network and medium congesting interference in the presence of mobility is also presented and analyzed. Simulations are conducted on OPNET Network Modeler and all simulation results are subjected to a 95% confidence analysis. The system presented is shown to meet all control system requirements.

Geodemlia: A Robust Peer-to-Peer Overlay Supporting Location-Based Search
Conference Paper
  • Sep 2012
Abstract—Existing peer-to-peer overlay approaches for location-based search have proven to be a valid alternative to client-server-based schemes. One of the key issues of the peer-to-peer approach is the high churn rate caused by joining and leaving peers. To address this problem, this paper proposes a new location-aware peer-to-peer overlay termed Geodemlia to achieve a robust and efficient location-based search. To evaluate Geodemlia, a real world workload model for peer-to-peer location-based services is derived from traces of Twitter. Using the workload model, a system parameter analysis of Geodemlia is conducted with the goal of finding a suitable parameter configuration. In addition, the scalability and robustness of Geodemlia is compared to a state-of-the-art tree-based approach by investigating the performance and costs of both overlays under an increasing number of peers, an increasing radius of area searches, an increasing level of churn as well as for different peer placement and search request schemes. The evaluation results reveal that in contrast to the tree-based approach, Geodemlia provides on average a 46% better success ratio as well as a 18% better recall at a moderate higher traffic overhead of 13 bytes/s and an increased average response time of 0.2 s.

Multicasting for Cascaded Fault-Tolerant Wireless Networked Control Systems in Noisy Industrial Environments,
Conference Paper
  • Sep 2012
This paper studies a Wireless Networked Control System based on IEEE's 802.11b Wi-Fi standard protocol consisting of two identical workcells with zero meter inter-cell distance. It is first shown how to improve system performance and increase the amount of noise that the system can tolerate without violating delay requirements or dropping control packets. Different noise models were studied. It was proved that increasing the short retry threshold increases system tolerance to noise. It was then shown through OPNET simulations that the two cell model is fault-tolerant at the controller level when either unicasting or multicasting is used. However, for the system to operate correctly in the presence of noise, multicasting had to be used.

On the Effect of Interference on Wi-Fi-Based Wireless Networked Control Systems
Conference Paper
  • Jul 2012
This study investigates a Wi-Fi-based Wireless Networked Control System. This system is first modified in order to enhance resistance to interference. Then, it is subjected to different types of interference. The system consists of a workcell containing 30 sensors, 30 actuators and 1 controller. All forms of interference modeled focus on the operating frequency band used by the control nodes. All simulations are conducted on OPNET Network Modeler and system performance is measured in terms of packet end-to-end delay and correct packet transmission/reception. All results are subjected to a 95% confidence analysis. The results show that intentional jamming is more damaging than medium congestion, which in turn is more damaging than network congestion.
