Advances in the areas of embedded systems, computing, and networking are leading to an infrastructure composed of millions of heterogeneous devices. These devices will not simply convey information but process it in transit, connect peer to peer, and form advanced collaborations. This ``Internet of Things'' infrastructure will be strongly integrated with(More)
On the one hand, enterprises manufacturing any kinds of goods require agile production technology to be able to fully accommodate their customers' demand for flexibility. On the other hand, Smart Objects, such as networked intelligent machines or tagged raw materials, exhibit ever increasing capabilities, up to the point where they offer their smart(More)
Today manufacturers require efficient reaction to critical events occurring at the shop floor. Therefore, device-level data needs to be integrated into business processes in a standardized and flexible way to avoid time-consuming media breaks. Current approaches are characterized by a late indication of changes in the production environment and a delayed(More)
— Massively deployed wireless sensor and actuator networks (WSAN), co-existing with RFID technology, can bring clear benefits to large-scale enterprise systems, by delegating parts of the business functionality closer to the point of action. However, a major impediment in the integration process is represented by the variety of customized WSAN platforms and(More)
This paper presents an approach for closely coupling enterprise systems and tiny wireless sensor nodes that are embedded into physical items. Coupling is done by implementing services from the enterprise system on the wireless sensor node system and by letting part of the business logic run on the nodes. The paper analyses concrete application scenarios and(More)

— The reliability of wireless sensor networks (WSN) is affected by faults that may occur due to various reasons such as malfunctioning hardware, software glitches, dislocation, or environmental hazards, e.g. fire or flood. A WSN that is not prepared to deal with such situations may suffer a reduction in overall lifetime, or lead to hazardous consequences in(More)
It is expected that millions of embedded devices and machines empowered with Internet technologies will be able to communicate, collaborate and offer their functionality as a service. At the shop floor, this creates new opportunities for more dynamic environments where timely usage of the monitoring information is coupled with control and in full(More)
Smart items are physical objects that are enhanced by information technology. There are a number of different smart item technologies available, all of which have different capabilities, protocols, and management functionality. These devices have become an attractive solution for enterprise scenarios. In such scenarios lifecycle management can become a(More)
