Wireless sensor networks are increasingly being used to improve business processes. The behavior of such a process is usually captured in models while its implementation is typically created manually. Besides being expensive, this approach entails deviations between the model and the implementation of a business process, thus rendering it less effective. We aim at closing [...]

Abstractions are crucial in order to manage complex systems. In pervasive computing, though, common programming abstractions tend to be too expensive for the employed resource-constrained devices. In recent years, the wireless sensor network community has proposed several solutions to this problem. However, little has been done to also support debugging on the level of the [...]

There is a long-standing dispute on whether and when thread-based programming should be preferred over the event-based paradigm. This dispute has also extended into the wireless sensor networks domain. Many existing operating systems rely on events due to their efficiency, but make code management difficult. Others rely on threads for developer comfort, but at the [...]

As computers get more complex, the task of programming them gets more complex as well. This is especially true for the “Pervasive Computer”, which is a massively distributed system consisting of unreliable embedded devices that communicate with each other over lousy wireless links. A common approach to address the programming problem is to offer programming [...]

Major motes operating systems like TinyOS or Contiki rely on an event-driven programming paradigm. While the use of events allows for limiting memory usage on resource-constrained motes, it may also hamper the development and debugging of applications, especially as their complexity increases [Dunkels2006]. Several authors also investigated the possibility of introducing threads to mote programming [...]
