Smart Dust Motes in Ubiquitous Computing Scenarios

The ubiquitous computing vision foresees that tiny computers, embedded into the environment and everyday objects are able to interact directly with the environment and each other, maintaining up to date information on the environment. Wireless sensor networks that are networks of tiny embedded computers can be viewed in a sense as a foundation for developing ubiquitous computing. In ubiquitous computing scenarios where the network nodes must realize a distributed application a sink-based data flow model, which is currently prevailing in the sensor networks field, is clearly not desirable. A service-based application model where the computing agents are situation aware is seen as a solution for realizing such applications. The article introduces the situation awareness concept for computing devices and describes some case studies. Ill. 2, bibl. 7 (in English; abstracts in English, Russian and Lithuanian).
