EmStar: Development with High System Visibility Author:

Recently, increasing research attention has been directed toward wireless sensor networks: collections of small low-power nodes, physically situated in the environment, that can intelligently deliver high-level sensing results to the user. As the community has moved into more complex design efforts — large-scale, long-lived systems that truly require self-organization and adaptivity to the environment — a number of important software design issues have arisen. To make software
