UBIQUITOUS COMPUTING: ADVANTAGES AND CHALLENGES

Ubiquitous computing is a relatively newer concept in terms of its actual implementation and further incorporation into everyday devices. It is a concept concerned with everywhere computing and does not live on any individual device but is in the woodwork. Ubiquitous computing (also called pervasive computing) is the growing trend towards embedding microprocessors in everyday objects so they can communicate information and make intelligent actions possible. The sharing of resources between physical and virtual worlds requires a particular kind of interaction to take place. And this makes it difficult to separate digital and physical security. This paper will presents an overview of the ubiquitous computing, the early work done in this field, examples from real life, advantages and challenges.
