Abstract
The smart cities vision relies on the use of information and communication technologies to efficiently manage and maximize the utility of urban infrastructures and municipal services in order to improve the quality of life of its inhabitants. Many aspects of smart cities are dynamic data driven application systems (DDDAS) where data from sensors monitoring the system are used to drive computations that in turn can dynamically adapt and improve the monitoring process as the city evolves. Several leading DDDAS researchers offer their views concerning the DDDAS paradigm applied to realizing smart cities and outline research challenges that lie ahead.
