Smart City is a constantly reshaped concept, embracing the future of dense metropolitan areas facing efficiency, sustainability, quality of life, and environmental issues. ICTs are enabling an evolution from the current duality between the real world and its digitized counterpart to a continuum in which digital contents and applications are seamlessly interacting with classical infrastructures and services.

From a wireless networking viewpoint, the digitization of cities can be seen as a paradigm shift extending the Internet of Things (IoT) to a citizen-centric model in order to leverage the massive data collected by pervasive sensors, connected mobiles or fixed devices, and social applications. The Agora research team aims at contributing to the following consequent challenges for wireless networks.

Deploying dense networks is challenged by the scale and versatility of the environment, yielding issues on the optimization of the placement of components and functionalities, and on autonomic protocols.

Machine-to-Machine (M2M) communication protocols running IoT architectures need a coherent rethinking to face the saturation of cellular networks while multi-hop networks are unable to cover large areas.

Exploiting the data carried by the network opens new questions for understanding the spatio-temporal dynamics of the users, reducing the traffic load, or improving on the reliability of the data.
