RERUM: REliable, Resilient and secUre IoT for sMart city applications

RERUM will develop, evaluate, and trial an architectural framework for dependable, reliable, and secure networks of heterogeneous smart objects supporting innovative Smart City applications. The framework will be based on the concept of “security and privacy by design”, addressing the most critical factors for the success of Smart City applications.

The Challenge

The rapid growth of cities aggravates many challenges associated with living in urban environments, such as public safety, transportation management, waste disposal, noise, air, and water pollution. Smart Cities provide ICT enabled services and applications to citizens, companies and authorities, driving competitiveness and improving quality of life. The Internet of Things (IoT) paradigm has been suggested as a solution. With IoT, objects like phones, cars, household appliances, or clothes become wirelessly connected and can sense and share data. A key challenge for IoT towards Smart City applications is ensuring its reliability, incorporating the issues of security, privacy, availability, robustness and flexibility to changing environmental conditions. Without guarantees that Smart City IoT objects are: (i) sensing correctly the environment, (ii) exchanging the information securely, (iii) safeguarding private information, users are reluctant to adopt this new technology that will be a part of their everyday lives, which decreases the market value of Smart City applications for the service providers.

Project Objectives

The ultimate goal of RERUM is to allow IoT to become the fundamental enabler towards a truly Smart City, having the citizen at the centre of attention. The key objectives of RERUM are:

  • Identify common threats and open security/privacy/reliability issues in existing IoT frameworks for Smart City applications.
  • Develop an architectural framework for the interconnectivity of a large number of heterogeneous smart objects based on the concept of “security, privacy and reliability by design”.
  • Embed security and reliability on the hardware smart objects, providing reliable, self-managed, robust and context-aware communications minimizing energy consumption.
  • Investigate the adaptation of Cognitive Radio (CR) technology in smart objects to minimize wireless interference and ensure the “always connected” concept.
  • Evaluate the performance of the framework in two real-world Smart City environments: Tarragona and Heraklion.


RERUM’s work is split into three major scientific and technical phases for optimizing the workplan and better monitoring and managing the progress of the activities:

  1. Architecture requirements and design
  2. Research and Development
  3. Trials development, experimentation and evaluation of results.

The work will be driven by the requirements of the target Smart City applications and by an assessment of the threats and open security issues in existing IoT frameworks for smart cities. The work will also follow an iterative approach starting from an initial definition of the architecture and the respective mechanisms that will be refined as the work progresses in order to mitigate any identified issues. The key scientific areas of focus of the project are:

  • Security, privacy and trust in IoT-based smart objects.
  • Information security and privacy in smart city applications.
  • Reliable interconnectivity of smart objects based on Cognitive Radio.
  • Energy efficient operation of smart objects.
  • Performance and scalability analysis of IoT.
  • Smart City applications.

Smart City Applications

RERUM considers four smart city applications to drive the requirements for system development and these will be developed and tested in the trials:

  • Outdoor 1: Smart Transportation.
  • Outdoor 2: Environmental monitoring.
  • Indoor 1: Home energy management.
  • Indoor 2: Comfort quality monitoring.

IoT Solutions World Congress-2015 and 2016

The RE-Mote, the hardware device created by Zolertia within the RERUM project, along with its core module, the Zoul, were presented in the two last editions of the IoT Solutions World Congress, yearly held in the trade fair space of Barcelona, in September, 16-18 of 2015 and October, 25-27 of 2016.

Zolertia’s booth mainly focused on showing these hardware products, RE-Mote and Zoul, and different applications of them were demonstrated to attendees, coming from industry and trying to understand how IoT and Industry 4.0 could be used to improve their businesses:

  • In the 2015 edition, a smart lighting solution was shown how to control, switch on and off and dimmer a street or an indoor lamp.
  • In the 2016 edition, the demos were about an industrial application connecting the RE-Mote to different industrial grade sensors, and a cold-chain application, monitoring goods carried into a freeze and using sensors from the UC-I2 Comfort Monitoring of RERUM.
  • Zolertia’s cold-chain demonstrator, implemented on a cool box using the RE-Mote, for the IoT Solutions World Congress 2016
