RIOT zolertia logo-large

A new release of RIOT OS has been announced on October 5th 2015.  The release, namely 2015.09 packs the following improvements:

  • A new generic (“gnrc”) network stack, a highly modular and configurable IPv6/6LoWPAN network stack. It implements a large number of IETF RFCs, such as RFC 2473, RFC 4861, RFC 4944, RFC 6550, or RFC 6775. It provides a unified API between the different layers and a generic network device interface.
  • A new timer subsystem is introduced by xtimer, replacing hwtimer and vtimer modules. xtimer offers very precise timer operations as well as support for long-term timers running over days and weeks. Along with well-known timer operations in RIOT, it also provides a function for accurate periodic timers.
  • Refactoring and cleaning up the peripheral drivers as well as other CPU and board specific code, helped to reduce the number of Makefile duplication lines by about 50% and provide a much cleaner and easier to use interface for porting new platforms to RIOT.

The Zolertia’s RE-Mote platform is included as an officially hardware platform supported in RIOT.

RIOT 2015-09

The RIOT community will offer long-term bug fixes for this release in a API-stable branch.

First long-range test with the RERUM Re-Mote platform


The RERUM Re-Mote platform was taken for its first long-range test early last week, and the results were promising: a 3.14 Km distance was easily achieved using IEEE 802.15.4g settings (50Kbps on the 868Mhz band), with an average RSSI of -56dBm, higher than the -110dBm sensitivity value our on-board CC1120 RF transceiver can achieve, thus being  possible to reach a higher distance!


The field test was done near Barcelona with two Re-Motes featuring simple omni-directional antennas with almost no gain, no special fixtures or highly-directive antenas, just good old duct tape and some amazing views at the Parc de la Serralada de Marina.

The results are shown below.

With new technologies and players like SIGFOX and the LoRa alliance betting on long-range solutions to unlock the Internet of Things (IoT), specially for Smart City applications, as well as industry-based solutions, the Re-Mote platform provides a compatible sub-1Ghz transceiver to build applications on top of these technologies, as well as IEEE 802.15.4g support to create Open Source solutions based on the best and most used standards.

RERUM aims to provide a complete architectural framework for dependable, reliable, and secure networks to support IoT and Smart City applications, with this goal in mind the Re-Mote platform was developed to tackle the specific need for long range and reliable communication, ultra low-power operation and robust operation.

RERUM’s digest of the IoT Forum, organised by BDigital Events

IoT Forum, Barcelona, 3rd December 2014

The data is the oil of XXI century and the IoT will help improve the quality of life of people and economic growth. We must be able, despite their maturity, to develop new innovative products and services that solve problems real for society to understand the IoT concept and see its potential.

This has been stated by most of the speakers during the second edition of IoT Forum that BDigital Technology Centre organised on the 3rd of December 2014 in Barcelona.

In the event, which brought together more than 300 professionals in the technology sector in the auditorium of Mobile World Capital Centre, speakers and attendees have agreed that the IoT will grow when a service or killer application is highly demanded by the citizens.

Through more than twenty presentations and discussions, it has drawn the IoT advances at global and regional level and has disclosed strategies, products and services that governments and companies have already implemented both in Catalonia and internationally.

According to Gartner, a massive use of the Internet of Things is expected in 10 years. Knowing these forecasts, Jordi Puigneró, General Director of Telecommunications and Information Society of the Generalitat de Catalunya, said flatly that:

Catalonia will be smart or not be. Or we put in front of transformation and surfed the wave, or we are on the beach waiting for the technological tsunami we pull over.

So he explained to the attendees the new Smart Region strategy, led by the Catalan government, to position the region as an intelligent territory of reference at European level. The initiative has two objectives: to create an intelligent industry producing technology products and services – and with it, employment in the digital economy – and to place citizens at the center of this digital strategy region. Puigneró recalled that the people are linked to the territory, but also to networks:

Facebook is the third most populous country in the world.

The IoT, catalytic smart industry

From real cases such as the Swedish multinational SKF – dedicated to the design and delivery of industrial products – Menno Van Rijn, director of Bax & Willems has shown international examples of how the industry has already implemented solutions based on IoT. Through implementations of the IoT in the automotive, aerospace, Van Rijn has referred to the changes that are occurring in business value chains, increasingly connected and smarter. This fact is resulting in devices monitored 24 hours a day, in the detection of incidents at the same time as they occur or the identification of behavioural patterns useful for predictive maintenance. He concludes:

The IoT will reduce the life cycle of all processes in the value chain of business and cause moving from a traditional mass production (from Asian countries to Europe) to production back to Europe, more localized, efficient and sustainable.

The IoT, serving the smart city

The market for Internet of Things is maturing and will gain popularity when you start talking about their real applicability

This was exposed by Albert Vidal, CEO of Effilogics, in the session From the smart smart city region, during which there were discussions on real examples of how the Internet of Things is already serving the built smart city and how this will be done in the next 5 to 10 years.

Irene Compte, from Urbiótica, showed real examples already done in the company, currently working on real projects in Europe and Latin America. Among them, a comprehensive information service on mobility in the French city of Nice. Compte explained that Urbiótica has 10,000 devices distributed worldwide in different projects and manages 1 million useful messages every hour in order to improve the management of cities.

Also, Jordi Cirera, showed the Sentilo platform as the Urban Barcelona platform for IoT data. Cirera added that anybody knows which is going to become the standard, but we have to be ready for the future one. Sentilo wants to be an open platform available for third parties.

For his part, Josep Laborda, ITS Project Manager of the RACC, has shown how technology can assist in the management of cities in the mobility area. Specifically, the app Infotransit, related to RERUM’s Use Case for traffic management, allows the status of traffic as the number of connected cars that are circulating. Laborda pointed out the need for objects to be connected not only to their provider, but also to the managers of transit. That is how different companies and agencies shall cooperate to provide more useful and commercial services.

From another perspective, Alessandro Bassi from Bassi Consulting introduced in his keynote speech that the IoT is not only technology and that it will arrive to all layers of our societies, from the technology to the social perspective and how cooperative business can be more powerful with IoT services and products.

The citizen, star of smart cities

The discussions generated from the various conferences have revealed that the citizen must be the protagonist in the construction of digital cities, to avoid, according to Josuè Sallent, director of Barkeno Advisors, having only sensorized cities. Sallent explained that some projects implemented internationally have had to be canceled because of complaints from citizens who have stated that the proposed services went against privacy and intimacy. Precisely that’s the reason why in RERUM privacy is a key point of research, in order to offer tools that can protect citizen privacy in spite of having thousands or millions of sensors surrounding us in future Smart Cities.

In general, all speakers agreed that the benefit provided to citizens and perceived by them to be the center of any project based on the IoT and that both companies and agencies should evaluate the return on investment (efficiency, transparency, etc.) before they run any proposal.

All the keynotes and panel discussions (some of them only in Catalan and/or Spanish) are available here.

Smart City Expo and World Congress, Nov. 2014, Barcelona – Some clues


Cities are where people live!

This was the opening statement made by Francisco Jariego, Director of Industrial Internet of Things (IoT), during the Smart City Expo & World Congress hosted in Barcelona, 2014.  Citizen’s needs are the ones paving the road to deploy the future Smart Cities, with infrastructure fitted to adapt to its citizen needs, configurable to enrich the set of services it can provide, as pointed out David Johera, Commercial Director of Wonderware, cities should be envisioned as a resource, changeable to adapt and react to its present landscape and citizen requirements, for example to adapt the garbage collection schedule on a given area, manage its water irrigation network to avoid wasting water, build mobility ecosystems and route traffic efficiently: improve the city quality life.

But Cities have also the obligation to become smarter in order to be efficient, as pointed by Michael Jansen from Cityzenith, a city needs to share its own resources and information, and effectively use the collected data and transform it into useful and comprehensive information, easily shareable between government entities and even with its citizens, to improve the strategies and decisions towards enforcing policies that enrich the City itself.

In any case targeting citizen needs also means dealing with citizen’s concerns, such as privacy and security. Nowadays, with the increasing number of smart-phones and people-driven applications, not all information sources are hardware: people, inadvertently or willingly, are sensors too.  IoT is not new to the industrial world; not so many years ago the lack of standards was a problem on how to integrate networks and services safely and securely. Now, even with the market driving the standardization efforts, the problem is still there, augmented by the proliferation of IoT applications, products and platforms, which has brought into our houses connected toothbrushes, air quality sensors, smart wearables and smart appliances … and Cities now investing in ubiquitously collecting data from our surroundings.  This opens more questions on the privacy and security of the data users, willingly or inadvertently, share while platforms and services are fragmented into isolated silos, governed by its own standards.

Still lot of work to do, so, but fortunately the RERUM project is progressing specifically in the privacy and security part, towards to an open and standard-based middleware that will cover this need very soon … stay tuned.

Gartner predicts Internet of Things will spark supply chain reaction, will transform data centres and create challenges


Techradar published that the analyst firm Gartner published a new report where they predict that a huge increase in the number of devices making up the Internet of Things (IoT), which will reach 26 billion by 2020, up from 0.9 billion in 2009, will have a significant impact on how the supply chain will operate.

According to Gartner, factors such as access to information about the supply chain and exposure to cyber-risk will become increasingly pertinent. In RERUM we also saw these risks in the WSN-based IoT and put the focus of the project in finding a technical solution to add reliability, privacy and security to the communication between devices.

Gartner, in another report published by Techradar, put the data centres in the eye of the storm of the IoT boom derived challenges, including security, consumer privacy, data management, networking, and server technology.

According to Techradar,

Security is a growing concern in the industry, and the increasing digitisation and automation of various devices in many different urban environments is likely to create new security issues. When coupled with the enterprise sector, where increasing volumes of big data present their own security challenges, it is not difficult to see that this will be a top priority.

Tied to security is the issue of consumer privacy, which is in the consumer consciousness now more than ever. The widespread adoption of smart devices means that more data is being collected on people than before, and any breaches in security will have a knock-on effect on privacy.

In RERUM we see also these challenges as opportunities and key enablers for a future with such amount of devices connected to internet that Gartner foresee.

Internet of Things: Freescale Addresses Challenges of Designing for the IoT

Security in the IoT is an important challenge that needs to be solved.
Geoff Lees, Senior Vice President and General Manager of MCUs from Freescale, one of the world’s biggest semiconductors manufacturers, highlights this in the above video (from 33″ to 1’07”): He underlines how important it will be to securely control the network access and security in the coming Internet of Things era.

This is one of RERUM’s goals.

Despite Freescale giving the maximum priority to the “Time-to-Market Focus Intensification” challenge, they identify “Securing information from the edge to the cloud” as the next important challenge “for making the IoT a reality”. RERUM focusses on Security and Privacy and Trust. We see Security as a main challenge and as a key enabler for the IoT. RERUM is assuming that companies, like Freescale, will solve the Time-to-Market challenge and bring technology to the market, that — implementing RERUM’s ideas and suggestions on those technology — allows building a more secure IoT.
