| Abstract |
The smart city is a new concept of urban development. It is about improving the life quality of city dwellers by making the city more adaptive and efficient, using new technologies that rely on an ecosystem of objects and services. The scope covering this new mode of city management includes: public infrastructures (buildings, street furniture, home automation, etc.), networks (water, electricity, gas, telecoms); transport (public transport, roads and smart cars, carpooling, so-called soft mobility - by bike, on foot, etc.); e-services and e-administrations. In recent years the concept of the smart city has become democratized, especially with the creation of several study groups and the establishment of more and more intelligent city in the world (New York, Paris, London ...). However, with the emergence of the Internet of Things (IOT) continues to boost the development of smart cities, it also increases the need to address security issues. The purpose of this article is the description of the data exchange flows between each component of the smart city and the users, to identify the types of protocol of these exchanges and the associated IOT applications. |
