7 Connected City architectures & framework

The first step is to identify several facts in applications of smart city concepts:

• Increase in new telecommunications services demand,
• Increase of migration between fixed and mobile applications,

• Increase of mobile applications costs

• Need of guidelines on QoS, data protection, resilience and security for new services.
• Most of the above facts generated silos solution for each services set.
The value chain and comprehensive platform supporting it, can be structured in 5 steps as shown in Figure 16.

Figure 16. Value Chain and Supporting Comprehensive Platform

Where the data collection stage includes sensors, devices, social networks, physical infrastructure and other existing
sources of information, actuators are considered as providers of its state data.
All data collectors send information using light protocols to gateways that route data through fixed and mobile
networks to a data warehouse. This sector could work automatically (i.e. M2M)
Services interact with data warehouse in order to provide information to services and from services to data warehouse.

The main objectives of a comprehensive system for smart city management are:
a. Compiling information on the city complying with the pertinent privacy legislation.

b. Distributing information, processed or unprocessed of the different services.
c. Analyzing information according to the defined criteria.

d. Making decisions by returning the refined information to the systems carrying out the different tasks.
e. Making data and capacities available in open format to society.

It is essential for smart city services to be supported by platforms that ensure they are correctly functioning, in terms of
efficiency, performance, security and scalability as well
