Sensor network in Internet of Things set-ups runs the risk of being disturbed by other wireless equipment, e.g. WiFi and Bluetooth. This project will develop a framework for dependable IoT applications.
Internet of Things – where the Internet reaches out to the physical world via wireless sensor networks – holds promises of smart cities, smart grids, and supportive applications in healthcare and industrial automation. In an IoT solution, a sensor network provides real-time information about the state of things and places. But today, Internet of Things set-ups run the risk of being disturbed by the use of other wireless equipment in the near surroundings, e.g. WiFi and Bluetooth, and by outdoor parameters. EU project RELYonIT takes on this challenge.
As of today, embedded wireless sensors and actuators in Internet of Things-solutions are deeply affected by their environment. Radio inference from other wireless equipment and electrical appliances, such as Bluetooth and WiFi, causes imperfect communication, and temperature and humidity variations affect battery capacity and electronics. For dependable IoT solutions, sensor data and actuation commands must be delivered reliably and timely and batteries powering devices must last for a given time in the order of years. Failure to meet these requirements may result in risks for humans and infrastructures, insufficient user satisfaction, and high costs. RELYonIT is an experimentally-driven, EU-funded research project that aims to develop a generic framework and tools for a wide range of dependable IoT applications.
The project integrates a range of different technologies from the embedded, computing and networking worlds. A multidisciplinary approach combines competencies in internetworking of sensors, sensor networking, dependability, modeling, verification, optimization, experimentation and testing, and real-world application.
“SICS’s role is in the modeling of environmental properties and their impact on IoT and we will design the protocol that will guarantee the dependability. We are also involved in how to use and, if necessary, change the protocol. For example, if data is not distributed correctly, how can the protocol be adjusted,” explains Thiemo Voigt at SICS.
RELYonIT will use several existing testbeds, the FIRE IoT facilities WISEBED and SmartSantander being two of them, with their wireless sensor networks that are connected to the Internet. The project consortium includes six members and will last for two years. Acciona and Wordsensing are two industrial partners that will construct user cases and scenarios as the project evolves.
“We will then develop two prototypes in order to demonstrate the capabilities of the techniques we use,” says Thiemo Voigt.
