It describes the challenges encountered, the managerial approach taken, illustrates the implemented initiatives, and how effective they turned out. The results might be relevant to faculty staff in managerial positions at regional universities all over the world that face the challenge to internationalize their teaching and learning environment for the benefit of their domestic students.

In this paper, we present our work focusing on an Ethernet network which is used as background interconnection technology for a smart home system in large buildings like tenements or an office block. In this case the network is larger and especially the applications are quite heterogeneous as compared to a private smart home system. Therefore, it is hard to supply a fair and quality of service aware network meeting all the demands. This is especially challenging in the case of an Ethernet network because this technology was intended to use it as a transparent connection system without the feature to support hard quality of service. We present how this problem could be solved by a middleware which best meets the special requirement of the mentioned use case. Finally, we discuss possible design improvements of this solution and present the recent Ethernet standards that could help solve this problem in an alternative way.

The fundamental idea is to change the individual behavior of each vehicle by exchanging information among traffic participants to realize a cooperative and more efficient ransportation system. Certainly, the evaluation of such systems is a comprehensive and challenging task in a real world test bed, therefore, simulation frameworks are a key tool to analyze IVC. Several models are needed to emulate the real behavior of a VANET in all aspects as much realistically as necessary. The intention of this survey is to provide a comprehensive overview of publications concerning IVC simulations of the year 2013 and to see how IVC simulation has changed since 2009. Based on this analysis, we will answer the following questions: What simulation techniques are applied to IVC? Which aspects of IVS have been evaluated? What has changed within five years of IVC simulations? We also take a closer look at commonly used software tools and discuss their functionality and drawbacks. Finally, we present open questions concerning IVC simulations.

Nowadays, Virtual Machine Monitor (VMM) - or hypervisor-based virtualization of servers is the de facto standard in data centers and a building block of the cloud hype. In recent years, virtualization has also been adopted to embedded devices such as avionics systems and mobile phones. The first mass deployment of embedded virtualization can probably be seen in video game consoles, though. However, it is still not employed by automotive electronics. This is despite the fact that with the upcoming domain controller architecture, virtualization can yield benefits beyond a mere consolidation of a multitude of Electronic Control Units (ECUs) into a few Domain Controller Units (DCUs). This paper presents merits of automotive virtualization, especially as a foundation for DCUs.

At the same time, the task load as well as the needs for performance increase. To address this problem, the A3Fa research project evaluates scalable distributed concepts for future vehicle system architectures. These can be seen as comparable to cluster-computing systems, which are applied in high-performance or high-availability use-cases. Methods used in such scenarios will also be important features in future vehicle architectures such as horizontal application scalability, application load balancing and reallocation, as well as functionality upgrades triggered by the user. This paper focuses on concepts and methods for the reliability of applications and hardware in future in-vehicle distributed system architectures. It is argued that future automotive computing systems will evolve towards enterprise IT systems similar to today’s data centers. Furthermore, it is stated these vehicle systems can benefit greatly from IT systems. In particular, the safety against failure of functions and hardware in such systems is discussed. For this purpose, various of such mechanisms used in information technology are investigated. A layer-based classification is proposed, representing the different fail-safe levels.

To satisfy that demand, the quantity of electronic control units in cars has increased dramatically. OEMs tackle that trend by consolidating software on powerful multicore hardware platforms. However, current software solutions are mostly static and designed to run on limited platforms. As promising operating system for automotive, Linux comes into consideration, which seems to scale better than already existing solutions. To ease the migration process of older software parts and guarantee freedom from interference according to ISO26262 between single software partitions, embedded hypervisors can achieve that requirements. Up to now, automotive systems are not developed to run within virtualized environments. Within this paper, we present an approach to map communication channels of virtual automotive ECUs and connect them with their already existing CAN interfaces. For our analysis, we use the Xen hypervisor. The focus for interaction between virtual machines is to use SocketCAN and given paravirtualized Ethernet drivers. Our goal is a non-intrusive software integration methodology. We keep the source code within software partitions as unmodified as possible. To benchmark our studies, we evaluate our implementation on the Intel i7 and the.

For a more detailed view we demonstrate a possible implementation of Cellular Communication Technologies in a data acquisition application for the collection of energy indicators in a medium-voltage grid. Furthermore, we show a technical overview of relevant and common mobile communication standards available in Germany. The included theoretical examples, Smart Grid scenarios, presented data and results are based on a research project for intelligent power regulation in medium-voltage grids performed in Regensburg (Germany). It is a joint project' of the University of Applied Sciences Regensburg together with a local energy provider and a manufacturer for distribution network systems.

In the future, the power grid will be smart. Based on different works, this article presents a data collection, analyzing, and monitoring software for a reference smart grid. We discuss two possible architectures for collecting data from energy analyzers and analyze their performance with respect to real-time monitoring, load peak analysis, and automated regulation of the power grid. In the first architecture, we analyze the latency, needed bandwidth, and scalability for collecting data over the Modbus TCP/IP protocol and in the second one over a RESTful web service. The analysis results show that the solution with Modbus is more scalable as the one with RESTful web service. However, the performance and scalability of both architectures are sufficient for our reference smart grid and use cases.
