The usage of RFID and sensing technologies in Supply Chain Management applications requires the automatic conversion of large amounts of raw data into manageable business process information. This has led to many performance and scalability issues in existing RFID infrastruc-tures. We present an approach to alleviate these shortcomings based on a flexible(More)
Contemporary BPM systems fit very well with traditional architectures that are based on a pull invocation principle, such as SOA. The proliferation of sensors and streams of events has led to event driven architectures that decouple event producers and consumers. EDAs are push-based and support different control structures. Future BPM systems must therefore(More)
As initial challenges of wireless sensor and actor networks (WSANs) are overcome, their application possibilities evolve. For these applications to move mainstream, efficient programming methods are required which can be used by domain experts. So far, the question of how can WSANs be efficiently programmed remains unanswered. In this paper we examine(More)
—Wireless sensor network protocols and applications typically need to be evaluated and tested not only using sim-ulators but also on testbeds. While simulations allow studying the performance of protocols and applications in a controlled environment, they usually do not provide a sufficient level of realism. On the contrary, testbeds allow exposing(More)
Embedded systems operating on high data workloads are becoming pervasive. ECA rule engines provide a flexible environment to support the management, reconfiguration and execution of business rules. However, modeling the performance of a rule engine is challenging because of its reactive nature. In this work we present the performance analysis of an ECA rule(More)
Comparing experimental results obtained on different wireless sensor network deployments is typically very cumbersome and in most cases unfeasible. This is due to the lack of a methodology to describe the properties of network deployments and the experimental conditions under which experiments have been run. Our work focuses on the design and development of(More)
There exist two major contributions of network technology to reduce CO2 levels: reducing the energy consumption of the network itself, and supporting areas of application to reduce CO2 levels. The impact of the latter is potentially higher. Therefore, we present TUDµNet, a testbed for a metropolitan-scale heterogeneous sensor network with hundreds of nodes(More)
—This paper highlights and characterizes the main obstacle to deploying a robust wireless sensor network testbed: the USB connections that link each of the nodes via ethernet gateways to the central server. Unfortunately, these connections are also the components that, when properly installed, can reduce testbed costs by attaching multiple nodes per(More)
In the last decade, several large-scale wireless sensor networks have been deployed to monitor a variety of environments. The declarative nature of the database approach for accessing sensor data has gained great popularity because of both its simplicity and its energy-efficient implementation. At the same time another declarative abstraction made its way(More)
This paper illustrates both challenges and benefits found in expanding a traditional game concept to a situated environment with a distributed set of wireless sensing modules. Our pervasive game equivalent of the Whac-A-Mole game, Whac-A-Bee, retains the find-and-seek aspects of the original game while extending the location, the number of players, and the(More)
