Experts from the Rockwell Science Center in Thousand Oaks, Calif., are developing technology for advanced sensor networks under the supervision of the U.S. Defense Advanced Projects Agency (DARPA) in Arlington, Va. The project, called Distributed Services for Microsensor Networks, is to develop a distributed runtime middleware environment for microsensor networks. The environment is to have domain-specific services, communication abstractions, and application program interfaces to allow plug-in of new applications, users, and systems. This software would allow applications to interact with sensor networks, such as enabling soldiers passing through a sensor network with handheld wireless computers to access intelligence information from the network. — J.K.
