Opportunistic vehicular networking: Large-scale bus movement traces as base for network analysis

Opportunistic vehicular networking: Large-scale bus movement...

International Conference on High Performance Computing & Simulation (HPCS)

作者： Michael Doering Lars Wolf Institute of Operating Systems and Computer Networks Technische Universitat Braunschweig Braunschweig Germany

In many road traffic scenarios the ability to communicate among traffic participants is very helpful. Therefore, research and development in academia and industry in that field exists already for many years and is ongoing in several directions. Some examples are Vehicular Ad-hoc networks (VANETs), e.g., using technologies like IEEE 802.11p, and vehicles communicating with backend systems, e.g., using 2/3/4G cellular networks. In opportunistic vehicular networks, vehicles may not only exchange data for the immediate use such as Cooperative Awareness Messages (CAMs) in the ETSI Intelligent Transport systems (ITS). Instead, a more general type of network might be set up, also for application scenarios beyond direct road traffic related aspects. For instance, buses of public transportation systems could collect data from the field or distribute data among several buses. Thus, buses could become an important part of smart cities or Internet of Things (IoT) application scenarios. Important questions are then, e.g., how much data could be distributed in such a bus-based opportunistic network or how often is it possible to exchange data between buses. Usually, buses in urban public transport systems follow well planned but nevertheless highly dynamic schedules and trajectories. Thus, traffic conditions have a significant and complex influence on bus mobility, causing very characteristic movement properties that are considerably distinct from other road vehicles. Understanding these special characteristics is essential for the design and evaluation of opportunistic vehicular communication networks. For this purpose we inspect two large-scale bus movement traces and describe the available data and metadata. Moreover, we analyze and compare vehicle density, speed, update intervals, and characteristics that are specific to public transport. Especially for large cities, but even for smaller ones if many devices like vehicles, sensors, and various other IoT things are part of suc

Towards Improving Realism of Perception in Artery

Towards Improving Realism of Perception in Artery

IEEE Conference on Vehicular Technology (VTC)

作者： Alexander Willecke Cengiz Yazici Keno Garlichs Lars C. Wolf Institute of Operating Systems and Computer Networks Technische Universität Braunschweig Germany

Simulation tools are frequently used to analyze vehicular networks. However, these tools are not ready yet to model the world in the necessary level of detail for Collective Perception. The network load generated by the Collective Perception Service highly depends on the sender's sensors, which are modeled insufficiently by current vehicular network simulators. This paper presents an Environment Model extension to Artery, a popular simulation framework for the ETSI C-ITS communication stack. It enables sensor-equipped vehicles to perceive objects from their perspective individually to improve the realism of perception. Furthermore, it adds new sensors that produce synthetic object data for detected objects based on the characteristics of various automotive sensors. A performance evaluation shows that the computational overhead for the extension is limited, so it is suitable even for large-scale simulation studies using Artery.

Energy-efficient voltage scheduling of peripheral components on wireless sensor nodes

IEEE International Conference on Communications Workshops, ICC

作者： Stephan Friedrichs Ulf Kulau Lars Wolf Technische Universität Braunschweig Institute of Operating Systems and Computer Networks Braunschweig

Much effort has been put into optimizing the energy-efficiency of wireless sensor nodes, but existing work exclusively focuses on the transceiver and the processing unit. Nevertheless, the peripheral energy consumption may dominate that of the entire node. We introduce the concept of a dynamically scalable peripheral voltage supply: Even for peripheral devices, a lower voltage level leads to a lower energy consumption. Each peripheral requires a different minimum operating voltage, but switching the voltage level consumes energy as well. We combine theory and practice to present an algorithm weighing off the benefits of a downscaled voltage level against the switching overhead, i. e., for calculating an optimal peripheral voltage schedule. Our approach is capable of self-parameterization and has been implemented and tested on a prototype, saving up to 47% of peripheral energy as compared to existing solutions.

FraST: Frankfurter Kreuz SUMO Traffic Scenario

FraST: Frankfurter Kreuz SUMO Traffic Scenario

IEEE Vehicular Networking Conference (VNC)

作者： Alexander Willecke Keno Garlichs Fynn Schulze Lars C. Wolf Institute of Operating Systems and Computer Networks Technische Universität Braunschweig Germany

Various traffic scenarios, whether synthetic or realistic, have been published for the traffic simulator SUMO. Many realistic scenarios containing various traffic situations were used in simulation studies on Cooperative-Intelligent Transportation systems applications, such as Cooperative Awareness and Collective Perception. However, new applications like Maneuver Coordination (MC) are used in different traffic situations, like on-ramp merging and high-speed overtaking, which are not the focus of present realistic scenarios. To facilitate research in the field of MC, we present and showcase the Frankfurter Kreuz SUMO Traffic (FraST) scenario in this paper. This scenario models highway intersections according to actual usage statistics, presenting a challenging environment for MC.

International Zurich Seminar on Broadband Communications

作者： O. Kunert Institute of Operating Systems and Computer Networks Technical University of Braunschweig Brunswick Germany

Field buses have been developed to fulfil real-time requirements of applications related to factory automation. However, they can only cover geographical areas such as factory halls or buildings which causes the occurrence of many small segments in larger environments unable to communicate among each other. In order to reduce this drawback a possible solution is to connect those field bus segments using interworking devices and a backbone network. A suitable backbone could be an ATM network. An interworking concept based on PROFIBUS/ATM bridges is presented in this paper. Simulations of an example PROFIBUS system were performed in order to study overall system behavior, to evaluate the feasibility of the presented concept and to show its limitations concerning the range of PROFIBUS applications it is suited for.

International Workshop on Web Content Caching and Distribution, WCW

作者： V. Kahmann J. Brandt L. Wolf Institute of Operating Systems and Computer Networks Technische Universitat Braunschweig Brunswick Germany

In scenarios where recorded presentations are streamed to a group of clients, users prefer to control streaming on demand and to get content in an individually adapted fashion. IP multicast, the obvious solution for group streaming, cannot provide such a level of flexibility. End-system multicast approaches alleviate the need for multicast routing, but require more powerful clients and are more complex regarding to reconfiguration and inter-client synchronization. The dynamic reflector we propose supports the latter issues by grouping clients with the same play-time position into one reflector session. Individual play-time position changes can be performed by opening new so-called reflector sessions or dynamically switching between them. We provide measurements to show that the latency introduced by the use of a dynamic reflector is low compared to other solutions. Furthermore, we provide scalability enhancements in terms of more efficient network resource usage and delay reduction.

International Conference on Connected Vehicles and Expo

作者： Tetiana Zinchenko Jan-Niklas Meier Burak Simsek Lars Wolf Volkswagen AG Institute of Operating Systems and Computer Networks Technische Universitat Braunschweig

ISBN: (纸本)9781479967308

In this paper we address prediction of the communication link quality for Vehicle-to-Vehicle (V2V) applications. We focus on the prediction at the receiver vehicle and suggest two novel frameworks, which allow real-time and short-term prediction whether a predefined application-specific QoS will be maintained in the near future. First framework makes use of machine learning approach, and the second one is realized with model-based estimation. Both frameworks are developed based on the measurement data which was gathered over the 5,5 month of the field trials in the sim project. In our paper we also suggest an optimization method to increase prediction accuracy and validate both frameworks through an additional real-world measurement campaign. The main advantages of suggested algorithms comparing to the existing work is their completely generic nature and low to no memory requirements. We demonstrate that in low network density scenarios prediction accuracy can reach up to 97%.

Enhanced transport bindings for efficient SOAP messaging

Enhanced transport bindings for efficient SOAP messaging

2005 IEEE International Conference on Web Services, ICWS 2005

作者： Werner, Christian Buschmann, Garsten Jacket, Tobias Fischer, Stefan Institute of Telematics University Lübeck Ratzeburger Allee 160 D-23538 Lübeck Germany Institute of Operating Systems and Computer Networks TU Braunschweig Mühlenpfordtstr. 23 D-38106 Braunschweig Germany

Within the past years the web service technology emerged into more and more fields of application. In some cases the classical approach of using HTTP as a transport binding for SOAP seems no longer adequate. As a full scale application protocol HTTP causes a high amount of protocol overhead and is too inflexible for many web service scenarios. In this paper we will initially give an in-depth review of existing transport bindings with a strong focus on data rate efficiency. Then we will introduce an advanced UDF binding called PURE that significantly reduces the protocol overhead and enables interesting additional features such as point-to-multipoint communication via IP multicast and broadcast.

International Conference on Mobile Ad-hoc and Sensor networks, MSN

作者： Robert Hartung Jan Käberich Christian Bunzeck Lars Wolf Institute of Operating Systems and Computer Networks Technische Universität Braunschweig Braunschweig Germany

A reliable energy supply is the foundation of many Wireless Sensor networks that can not be powered from mains power permanently. Therefore, batteries have been widely used since many years. However, due to their environmental impact and limited lifetime, costs are high and they should be used most efficiently. Further, predictability is challenging and overprovisioning is common practice, which once again increases costs. Hence, energy harvesting has become very popular and can increase lifetime, reduce cost, but comes with additional challenges. Outdoor Wireless Sensor networks operate in varying temperature ranges which has a noticeable impact on the energy sources. In this paper, we characterize different types of energy sources regarding their behavior under usage patterns and temperature changes,

IEEE Vehicular Networking Conference (VNC)

作者： Tobias Pögel Lars Wolf Institute of Operating Systems and Computer Networks Technische Universität Braunschweig Braunschweig Germany

Vehicular communication using cellular networks is an increasingly important issue and provides additional functionality as well as services with highly topical information. Due to the mobility of vehicles, network coverage or current utilization, frequent changes in the communication properties occur, for example spontaneous significant changes in the available bandwidth. Not all applications can handle such delays or interruptions very well. Moreover, the communication scheduling is not optimal because communication changes come without any prior warning. In many cases it would be helpful if additional knowledge about the future properties is available. In this work we show how to exploit vehicles which go around collecting data about their current communication conditions and transfer the data to a central server database. On the server side we can make predictions about the future connectivity by taking into account various influences and the network dynamic. The vehicles can simultaneously request predictions for their surrounding area and benefit from the historical network data of other vehicles. Finally, the different vehicular applications are provided by such predictions and can be used in different ways. We describe the process of establishing such a Connectivity Map including the necessary steps to collect the data and to predict network properties to support vehicular application with additional context information. Thereby, we also investigate the accuracy of our Connectivity Map in an experimental evaluation scenario.
