Smart Cities, IoT, and e-Government: Applications in Greek Municipalities

The smart city era has already begun and its societal and environmental implications in urban development are expected to be huge. In this context, Internet of Things (IoT) technologies have become the major path towards novel e-Government practices, to improve citizens’ quality of life, increase the efficiency of infrastructure and services, promote sustainable economic growth, and integrate multiple city sectors, creating an interconnected and smart urban environment. This work offers an up-to-date survey of smart city definitions, their development framework, their characteristics, and their areas of application. Furthermore, it provides the current state of smart city applications in Greek municipalities and a proposed comparison among them, in terms of well-accepted key performance indicators, while it comments on their suitability in the context of e-Government and the challenges that must be faced regarding their efficient implementation.
