According to the United Nations, 54.5% of the world population is living in cities today, a number that will reach 60% by the year 2030. To provide services and resources to this new wave of inhabitants, cities will have to be more efficient. Technology will be key to improve city efficiency, and research on Smart Cities is investigating how Information and Communication Technologies (ICT) can help citizens and governments to improve quality of life in the cities, particularly those in developing countries that will experiment higher growth rate on the next decades. 
Smart City technology have a direct impact on the lives of millions. Recently, a bug on the widely used traffic routing application Waze drew the city of São Paulo to a halt, as thousands of drivers were led by the app to use the same route. Smart City systems and platforms must be deployed in large scale, include devices from different architectures that use distinct communication protocols, process large amounts of data, must be reliable and bug-free. As such, distributed approaches to Smart City applications are preferable, even though there is a trend of creating centralized architectures which can be dangerous to cities on long term. This workshop aims at gathering distributed systems researchers that are working on distributed approaches for Smart City platforms and applications.
