To address the real-world challenges in sensor network evaluation, testbeds have been proposed to enable experimentation without taking the typical deployment hurdles of robustly mounting the hardware, installing batteries, and instrumenting sensor nodes for data collection. In the recent past, several research institutions across Europe proposed to(More)
Wireless sensor network protocols and applications typically need to be evaluated and tested not only using simulators 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 protocols(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)
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 infrastructures. We present an approach to alleviate these shortcomings based on a flexible(More)
Due to recommendations from government agencies such as the U.S. Department of Defense or the Food and Drug Administration, mandates from private sector companies such as WalMart, Metro or Tesco, and even visions such as that of the Internet of Things, Radio Frequency Identification (RFID) technologies have gained great thrust. The widespread realization of(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)
In this paper we suggest a multiagent based middleware architecture that is particularly suitable for supporting wireless sensor network deployments in industrial environments like mines and chemical processing plants. Our intention is to make the proposed middleware architecture to be as closely aligned to the Foundation for Intelligent Physical Agents(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)
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)
