New sensor, communication and software technologies are used to broaden the facilities of tracing and tracing systems for food transports. An embedded assessing unit detects from sensor data collected by a wireless network potential risks for the freight quality. The estimation of the current maturing state of agricultural products will be supported by(More)
In this paper, we investigate possibilities and limitations of temperature change as a method for information display in mobile applications. While some widespread and well-recognized haptic displays such as force-feedback often trigger the user's immediate attention, we will focus on ambient strategies for tactile information display, that is, the display(More)
Scenario setting The previous chapters described the application of autonomous cooperation on embedded systems, in sensor networks, transport planning and communication systems. For practical demonstration of the implications of the described studies the prototype of the intelligent container was linked to an agent system for transport coordination(More)
In this demonstration a research prototype for autonomous local control of logistic processes in the transportation domain is presented. The aim of autonomy in logistics is to gain flexibility and robust-ness in process execution as well as increasing promptness and reducing human efforts in the coordination of a logistic process. This is enabled by(More)
Large-scale recordings of neuronal activity make it possible to gain insights into the collective activity of neural ensembles. It has been hypothesized that neural populations might be optimized to operate at a 'thermodynamic critical point', and that this property has implications for information processing. Support for this notion has come from a series(More)
platform for secure communication in wireless sensor networks for logistic applications. Abstract In this paper we present a new methodology for the integration of security provisions into protocols for wireless sensor networks. There is an ever growing demand for security in communications in general. As wireless sensor networks (WSN) face real-world(More)
In this paper a promising application for wireless sensor networks (WSN) in future logistics is described. We present a hardware infrastructure for the intelligent container that enables real-time transport supervision and dynamic quality forecasts for sensitive and/or perishable goods. This is achieved by employing a WSN system in conjunction with a(More)
RFID and sensor technologies will have a great impact on supply chain logistics in the next years. Linking these technologies is an essential factor for cost reduction. Besides the direct hardware link we present a solution that allows Online-Access to the sensory environment of each transport item and enables automated supervision of surrounding(More)
