Wireless sensor networks are currently the subject of intense research and many prototype installations are currently investigated. However, most of the existing sensor network installations have in common that they are not considered time critical. No immediate action has to be undertaken as a response to the received data. In contrast, many envisioned future application areas of wireless sensor networks (such as plant automation and control, traffic management, medical applications, emergency solutions) require immediate and guaranteed actions. In such environments, data has to be transported reliably and in time through the sensor network towards the end user. To make the networking task more complex, in many applications the end user or the controlling intelligence is located remotely (e.g., remote monitoring, supervision and surveillance applications), and the wireless sensor network interworks with other networks (e.g., fixed infrastructure cellular, Internet). Due to the lack of appropriate models, components and protocols, it is currently very difficult to construct and operate a wireless sensor network with performance guarantees. Thus, the commercial success of wireless sensor networks in many application areas is unsure unless this particular problem is understood and solved.

The PWSN workshop will bring together researchers and practitioners working on performance issues within wireless sensor networks. The workshop intends to examine research challenges associated with achieving dependability in WSNs, share experiences from real-life deployment of dependable sensor networks, discuss application-dependent wireless sensor-actuator design methodologies, illustrate dependable MAC, network and transport protocols, and in general, explore issues of reliability in WSNs.
