One of the truly multidisciplinary research efforts involving computer scientists revolves around the topic of sensor networks. It brings together chemists who develop the sensors, engineers focusing on wireless platforms and other hardware components, and the computer scientists who develop the services, knowledge layers and middleware. In many cases, research must also include the knowledge workers associated with the specific domain, many of whom are represented in the articles in this issue of ERCIM News. In almost all cases, some aspect of the research will seek to create a bridge or bidirectional channel between the physical world of the planet, its people and the sensors, and the digital world of computers and their software applications.
