Preface

Our research group in the Embedded and Pervasive Computing Laboratory at Shanghai Jiao Tong University began working on various pervasive computing projects in 2006. At that time, smartphones had not been invented, and cloud computing had yet to gain momentum. To realize the focal point of pervasive computing (i.e., computing anywhere and anytime), we mainly used a combination of personal computers, personal digital assistants (PDAs), and small sensors. Because we work and study primarily at the university, the pervasive applications developed over the years focus on a campus environment for providing relevant services, such as a campus map, short message service (SMS), photo sharing, and a campus search.

Looking back, many of the services ...
