This paper presents the current state of our research in realtime communication of an IP-based in-car network. The Internet Protocol (IP) will serve as convergence layer of different specific in-car network protocols and IEEE 802.3 Ethernet will be the basic technology to transport IP. In this work, we evaluate a legacy switched Ethernet network without any(More)
In current vehicles, a large number of control units are connected by several automotive specific communication buses, facilitating innovative distributed applications. At the same time, computers and entertainment devices use IP and commodity communications technology like Ethernet to connect to the Internet, allowing for innovative solutions and(More)
As of today Ethernet is used in the in-vehicle network mainly for two use cases: connectivity between the head unit and the rear seat entertainment (RSE) as well as faster onboard diagnostics (OBD). With the increasing bandwidth demand in driver assistance and the wish to easier interconnect the driver assistance and infotainment domains additional usage of(More)
The traditional in-vehicle network is changing due to the increasing number of advanced driver assistance systems (ADAS) and the bandwidth demand of future applications. Instead of using MOST for multimedia applications, there are some efforts of the automotive OEMs to introduce Ethernet for these applications. The legacy switched Ethernet network is not(More)
AIM To identify the factors associated with participation in gastric cancer screening programs. METHODS Using data from the Korea National Health and Nutrition Examination Survey 2005 (KNHANES III), a nationwide health-related survey in Korea, a cross-sectional study was performed to investigate the multiple factors associated with gastric cancer(More)
Ethernet-based in-car communication is currently a hot topic in the automotive industry. Soon Ethernet will start to oust MOST bus in its domain of infoand entertainment applications. However, the full benefit of a technologically integrated in-car network will only become rewarding with the deployment of an Ethernet-based backbone that integrates all(More)
Today's premium vehicles are some of the most complex consumer goods-featuring a large number of different functionalities. These functionalities are being implemented by numerous Electronic Control Units (ECUs), which are often interconnected with CAN, FlexRay, LIN, and MOST. However, some car models already use Ethernet for high bandwidth applications,(More)
Switched Ethernet is widely used for all kinds of applications. However, for demanding multimedia streaming applications in a fully-loaded network, legacy Ethernet is not the best choice due to its limited Quality-of-Service (QoS) support. The new specification of the IEEE 802.1 Audio/Video Bridging (AVB) standard, an extension to legacy Ethernet, provides(More)
This paper presents the concept and preliminary performance evaluation of a stochastic network discovery approach named opportunistic scanning. Therein, a station only pauses its communication for an extremely short time interval to scan for other technologies / systems. The selected scanning duration is short enough not to be noticeable by higher layer(More)
