Introduction to the special section on pervasive computing

Abstract

After nearly two decades of its introduction, pervasive computing has gained much popularity. The first perspective was to provide services in an anytime/anyplace paradigm [1] . Today, most of the elementary services such as Internet, email, billing, mobile games, etc. are provided via smartphones in this manner, thanks to the ubiquitous infrastructure as well as mobile computational devices. However, the other goal, which is invisibility, is far from today’s reality. The invisibility idea indicates an environment in which services have interweaved so tightly in people’s life that have disappointed from their vision.
