The vast diversity of current sensing devices and mechanisms enable the creation of data-rich environments which gives the opportunity to create smart systems. The smartness of systems must transcend individual interests and fulfill collective aspirations and environmental needs. Therefore, new products, processes, enterprises, communities and any kind of systems must be envisioned as Sensing, Smart and Sustainable (S3). This paper discusses the trends and challenges for S3 applied to everything. Furthermore, it suggests that the knowledge produced in the field of collaborative networks might be used to leverage the S3 capabilities.
