International Workshop on Sensor Network Architecture (WSNA'07) April 24, 2007 - Cambridge(MIT Campus), Massachusetts, USA. [Overview] Wireless Sensor Networks (WSN) is a new technology with many promising applications, such as military surveillance, infrastructure protection, scientific exploration and smart environments. Researchers in this area have accumulated a large portfolio of components, effectively addressing a wide range of individual research problems. However, because of the limited understanding on how to integrate these components effectively, we are facing an urgent and challenging question on how to build sensor network systems efficiently. To facility the collaboration on and convergence of future sensor network architecture, WSNA is seeking for novel ideas which specify the essential principles that guide sensor network design. In particular, we are interested in architecture-level service and control interfaces, function decomposition and partitioning, composition methodologies of functional components, high-level engineering of sensor network protocols, and integration of wide-area sensor networks. We strongly encourage philosophical position papers that bring out interesting and novel ideas at an early stage in their investigation.
