Pervasive computing is emerging as the new paradigm for the XXI century. Although it may be a new concept for many, its first ideas were introduced in 1991, in the seminal paper of Mark Weiser (Weiser, 1991). The primary vision of such a paradigm is that computing becomes part of our lives, being available anytime and anywhere. In other words, it replaced the idea of each person using a single computer at a time (i.e., the personal computer paradigm) to the one where each person can use many computers, which are embedded in everyday life objects (e.g., clothes, phone and automobile).
