Smart cities are cities that use digital technology to enhance the quality of life and public services for it’s inhabitants. The concept is too young to provide formal boundaries, but we can talk about it’s fundations and building blocks. I like depicting the building blocks in three steps, situational enablers, technology embedding, and key features. In the bottom we have growing social acceptance of the digital world Which goes along with a political environment that demands transparent administration and efficient management. The infrastructure that is already in place for public safety and security has shown the citizens the benefits of connected services The fast growth of metropolitan areas requires financial sustainability that many modern cities lack Finally, our planet needs us to switch to a predonminantly transit-oriented green environment with a minimum carbon footprint. In the top row, we have the key features that would raise the IQ of a city >Smart Resources: Smart Grid, metering and delivery of Electricity, Gas, & Water >Smart Mobility: Inteligent congestion management, and reliance on public transportation and electric vehicles >Smart P.S: Safety, healthcare, lighting. >Smart Building and homes: Efficient monitoring, HVAC, and private safety (detectors, locks) > Smart Integration of information accreoss departments and between the public and private sectors, to provide more faster and better services, and creating opportunities for innovation. In order to get to the last stage, we need a fundation of physical objects communicating with processes, data, and people, embedded with electronics, sw, sensors, and network conectivity. A pervasive broadband network, like city-wide WiFi service (Smart+Connected City Wi-Fi), will provide connectivity to users and devices all over the city. IPv6, among other features, will provide enough unique addresses for the forseeable future. The biggest Issue is defining one flexible and interoperable system that homogeinizes communication The IETF proposes a solution embracing a web service architecture that can be extended to IoT nodes, Representational State Transfer (ReST). And defines different protocols stacks for constrained and not constrained devices. "We built this city..."
