Today’s landscape of research is really varied and specialized at the same time. Many daily advances appear relating telecoms, health, information technologies, transport, and a countless list of interesting domains. This conference makes a multidisciplinary unique event devoted to a hot topic: the revolution to occur in our cities. 
Nowadays, cities evolve rapidly, as a response to the big number of people who already live or plan to live in them (up to 70% of world population in 2050). This provokes a growth of the demand of new services, as much as it creates new challenges to city managers and frustrates citizens who see their commodity, health, and economy negatively affected by the shortage of proper solutions. 
There exists then a new domain of work, either for research, development, and innovation, consisting in addressing the very complex problems that appear in our cities. The "Smart City" term has recently born as a worldwide joint effort aiming at achieving a holistic (integral, coordinated, global) management of resources that hopefully will satisfy three main players: citizens, city managers, and the companies deemed to actually implement the solutions. 
One capital issue in smart cities not to be underestimated is the holistic nature of all problems and solutions, way beyond the up-to-now too much focused studies in one part of it. Countless interactions exist between a problem, a service solving it, its users, its managers, and providers. Many horizontal implications exist (relation to other parts or services) as well as many vertical approaches for a solution can be offered (with possibly different quality of service). 
This conference welcomes researchers and scientists in particular, because one of the main challenges to address is a higher implication from Universities and research organizations in this domain, so as to give coherence, organization and add a knowledge layer to the present situation of smart cities.
There is a clear goal here in presenting new results, either coming from research, development and innovation, to create an international pole of attraction for people (and knowledge) who will enhance their scientific and practical know-how on the many different niches of work in smart cities.
