The platform will be based mainly on components subject to open-source licensing, in order to
facilitate its re-use and dissemination. It will also enable its use by other local entities with the
possibility of implementation without dependence on a pre-determined supplier.

In all developments and applications, the use of free and open-source software is prioritized as
far as possible.

The platform facilitates integration with diverse data sources and multiple structures through a Big
Data approach. It will be able to amalgamate information from sensors and actuators managed
by the city (e.g., traffic lights, street lights, irrigation of parks), as well as from citizens’ devices
(such as mobile phones), structured, non-structured and semi-structured data, social networks and
data streams and other IT management systems such as SCADA – Supervisory Control And Data
Acquisition, Big Data sources (streaming listening) and management solutions implemented in
the city council.

This component abstracts from the acquisition mechanism and the origin of the data (e.g., device,
ICT system, log) enabling the implementation of semantics established and validated by the city
council, among others FIWARE.

The platform enables integration with standardized open M2M and database messaging protocols,
as well as web services and files, which have specific connectors with the main protocols used in the
IoT world, including HTTP, HTTPS, MQTT, MQTT-S, CoAP, REST and XMPP. They support lightweight
structured file formats such as JSON, GEOJSON and Ultralight 2.0. The platform also supports
IPv6-based communications and sensor connections that make use of specialized protocols such
as 6LoWPAN and LPWAN-type access technologies, including LoRa, NB-IoT, Cat M and Sigfox,
which provide the corresponding connectors for current and future elements.

7.4 Set of operational IT solutions for integrated city management

The Riv@ Smart platform aims at the true interoperability of smart services deployed vertically with
the different independent management systems of each service. The most prominent are:

• The entire infrastructure of the IP multiservice network supported by Rivas Vaciamadrid, based
mainly on fibre-optics that converge with other infrastructure, Broadband Plc, IoT NarrowBand,
Wi-Fi (Wifi4EU), LTE-Security and emergencies.
