Abstract: Embedded Systems are a crucial technology for competitiveness. The vision of pervasive computing is that objects, buildings and environments may be endowed with software intelligence to improve human interactions both with the individual objects and with the system as a whole. Many intelligent embedded systems move rapidly within a physical environment. While the best complete algorithms are doubly exponential, probabilistic algorithms have emerged that have very good practical performance, and probabilistic guarantees of convergence.
Embedded Systems
'Intelligence' takes account of autonomous reasoning and acting in a co-operative manner. 'Ambient Intelligence' refers to an exciting new paradigm in information technology, "in which people are empowered through a digital environment that is aware of their presence and context and is sensitive, adaptive and responsive to their needs, habits, gestures and emotions." This applies not only for people-centred tasks, which, of course, seems the most exciting, science-fiction-type, aspect, but also for purely technical solutions like smart sensors, actuators and control systems, especially in safety related applications.
Heterogeneity (of environment, applications, protocols, etc.), autonomy (self-awareness, self healing, self-organizing, etc.), nomadic mobility (ad hoc, unreliable, heterogeneous, etc.) and scale-less (number of users, geography, structure, etc.) are the new emerging embedded systems challenges.
Used in everything from consumer electronics to industrial equipment, embedded systems —small, specialized computer systems stored on a single microprocessor — are playing a major role in the growth of the Internet and the boom of wireless communication channels.
Due in part to embedded systems, more and more consumer products and
