A controlled network is a network of nodes that collectively monitor, sense, and control or enable control of an environment for a particular purpose. A home appliance network is a good example of a controlled network. In fact, thousands of controlled networks already exist in everyday life in automobiles, refrigerators, traffic light controls, city lighting systems, and on factory floors. Control networks vary enormously in the number of nodes (from three to thousands) in the network and in their complexity. Controlled networks are an important aspect of what is sometimes called ubiquitous computing.
