Zolertia and Orange Labs Spain will present a new paper in upcoming Smart City Expo World Congress 2011 in Barcelona

Smart society for innovative and sustainable cities November 29 - December 2 2011, Barcelona, Spain.

The population density of cities demands actions to be taken to ensure sustainable and environmentally-friendly economic growth that is capable of improving the quality of life of their inhabitants. This is their main challenge and the reason why society is calling for more Smart Cities.

Through keynote conferences, round tables and parallel sessions, the congress will be inspiring debate on the different issues raised in the programme. Speakers of recognized prestige and representatives of the leaders of the most innovative Smart City initiatives around the world will be attending the SmartCity World Congress.

Zolertia and Orange paper on their most recent project "Reconfigurable IPv6-enabled wireless sensor network for urban monitoring and street light control in city environments" got accepted by the evaluation committee, and will be presented in the upcoming Smart City Expo World congress. This work summarizes our experiences in past IPv6 day where we launched a demo scenario proving that IPv6 enabled sensor networks can be easily integrated in existing frameworks and can provide tools for understanding and managing the city resources, by efficiently monitoring and controlling key variables such as temperature, street lighting and others.

We will be present in the congress sharing our insight and experience with fellow researchers, developers and council authorities.

As requested by many users and attendees, we can schedule quick meetings to inform you about our recent work, projects and proposals for a smarter planet. Please write us at or and give us a brief information about you, your interests, and the time/date you will be passing by our stand, we will do our best to reserve some time in advance.

WSN in the Real World ­ A Workshop

ZigBee Alliance Fall 2011 Members Meeting – OPEN TO PUBLIC – October 28 2011 – Barcelona, Spain

This free public workshop will provide attendees the opportunity to exchange wireless sensor network (WSN) information on standards, markets and projects, with a particular focus on the European market. Attendees will gain an understanding of European Commission research and development in this area as well as a view of local projects and deployments in Spain.

This workshop brings together researchers, developers, program managers and ZigBee subject matter experts to share information on projects, research and development, deployments and markets for wireless sensors in Europe. Sharing experiences and vision into the future on requirements and results of R&D projects related to WSN will enable participants to identify opportunities to exploit new results as well as allow researchers to understand how commercial markets drive ZigBee standard development.

The workshop is a collaborative effort by i2CAT, a research and innovation center in Barcelona, the European Commission (EC) Framework 7 R&D program and the ZigBee Alliance.

Zolertia will participate with a 10 minutes pitch in which we will show two Real-world deployment examples (Smart Cities and eHealth), and will be taking questions from the audience about latest research and activities. As participants of the workshop we will provide an insight of our opinion about ZigBee and the new standards coming along.

Zolertia Z1 mote reference in: Wireless Inverted Pendulum using IEEE 802.15.4 Protocol

Inverted pendulum control system: One computer with NI board, three motes and the inverted pendulum, taken from (1)

A comparison between the two main implementations of IEEE 802.15.4 standard in TinyOS is performed by Aitor Hernandez, implementing Guaranteed Time Slots (GTSs) mechanism and all the necessary features to transmit during the Contention-Free Period (CFP): allocation, expiration, reallocation and deallocation, making a comprehensive evaluation with which the behavior of this mechanism is proven. The implementation is validated in terms of packet delivery rate and delay for different network configurations and different parameters.

The Zolertia Z1 mote comes up as a solution and best candidate to replace telosb/tmote sky motes as it allows to use crystal faster than 32.768kHz and its 96kB of ROM will allow to use the debug utility of GTS implementation provided by TKN15.4,dbg_serial, as well as more features.

Thanks (again) for considering us in your projects!

Zolertia Z1 mote reference in: IEEE 802.15.4 Implementation based on TKN15.4 using TinyOS

Transfering radio token between components responsible for superframes

The purpose of this technical report is to provide a reference guide to the GTS implementation described in the IEEE 802.15.4 protocol specification based on the TKN15.4 implementation. The GTS implementation is available for the TelosB/TmoteSky platform, but soon will be available for the Z1 mote as well as we are planing to port it officially in trunk!

Available files will be linked here from github devel branch until merged to trunk officially.

Zolertia participates in 7th IEEE International Conference on Distributed Computing in Sensor Systems (IEEE DCOSS '11) held in Barcelona

Pitch session for demos DCOSS'11 (Thanks Joel Höglund (SICS) for taking the photo!)

The 7th IEEE International Conference on Distributed Computing in Sensor Systems (IEEE DCOSS '11) took place at the Casa Convalescència in Barcelona, Spain during Monday, June 27 - Wednesday, June 29, 2011.

Sponsored by: IEEE Computer Society Technical Committee on Parallel Processing (TCPP) IEEE Computer Society Technical Committee on Distributed Processing (TCDP)

Held in co-operation with: ACM SIGARCH, ACM SIGBED, European Association for Theoretical Computer Science (EATCS), IFIP WG 10.3

We participated presenting in the Demo session held on June 27th, with a demo titled "Zolertia's IP-enabled flexible and open smart sensing platform" in which we show several mashups and applications running over IPv6 on both Contiki and TinyOS. This is the list of the presented applications:

  • IPv6 monitoring network for urban environments (Temperature, Humidity, Atmospheric pressure and Carbon monoxide).
  • Real-time light control using an accelerometer and interrupts for elderly care applications.
  • Current consumption metering using our own Starter Platform as a measurement device.
  • High-speed sound pressure sampling using a custom sound board.

Soon we will upload the code to the applications section of the respective operative systems for you to try and develop. If you would like the code ahead of publishing you can email us

Zolertia participates in ITU-ICTP Workshop on Applications of Wireless Sensor Networks for Environmental Monitoring in Developing Countries held in Trieste, Italy, 2011

Workshop organized by ITU and ICTP

Environmental data can enable important advances in science, medicine and policy. However, only limited resources are currently available in many developing countries. The way it is currently implemented, environmental monitoring is based on macro-infrastructures that use carefully calibrated and highly accurate professional equipments which are sparsely deployed at a relatively small number of fixed locations by official organizations. This creates a visibility gap that may be bridged through micro-infrastructures based on complementary sensing technologies and systems. The purpose of this workshop is to learn more about and discuss the use of wireless sensor networks for environmental monitoring. Wireless sensor networks require low power and are not dependent on any existing network. It is also a low-cost technology. The vast range of sensors that can be connected to the devices makes them flexible for many different applications such as air quality, water quality and soil moisture monitoring.

Organized by: ICTP ITU

Zolertia participate in the workshop as facilitator, sharing with the attending crowd our experience in wireless sensor network design using Contiki and IPv6, as well as clearing basic concepts about electronic design. Our lectures were:
