Rotten bridges and highways, the raised population density and car penetration as well as daily and long-time roadworks are just a few reasons of the modern transportation challenge: the steadily increase of traffic density. This unavoidable trend also comes along with the well-known negative effects such as traffic jams, car accidents and CO2 emissions. Hence, current research approaches aim on generally...
Resilient Smart Grids require very robust communication infrastructures, which allow to support the control of the Smart Grid even and especially in critical situations. Current network quality assurance processes, such as drive tests in wireless systems, typically focus on cell coverage and quality of service parameters (e.g., max. data rate) at a specific geographical position, without considering...
Commonly used unmanned aerial vehicle (UAV) platforms rely on the use of global navigation satellite system (GNSS) receivers for navigation. To enable the autonomous navigation of cooperative UAVs in GNSS-denied environments, the use of an ultra-wideband (UWB) positioning system is proposed. This paper discusses the design and evaluation of a practical and cooperative UWB positioning system using...
The steadily increasing traffic density is causing enormous negative effects such as jams, accidents or CO2 emissions, especially in urban areas. In Europe more than 12% of the traffic network is daily congested. Hereby a reliable and dynamic congestion forecast is the key to avoid and/or compensate such locale bottleneck situations. Hence, this contribution focuses on a cloud-aided, lane-specific...
Positioning techniques based on satellite navigation systems are nowadays standard in most commercial vehicles. But GPS receivers in general are effected by multipath and atmospheric effects and hence their performance may be decreased, especially in challenging environments that directly affects the usage of satellite-based positioning in traffic-relevant and by that safety-critical systems. Therefore,...
