|10h10||IoT CONNECTIVITY IN INDUSTRIAL CONTROL APPLICATIONS|
Wireless connection of sensors and actuators in industrial environments not only enables wireless monitoring and actuation, it also enables coordination of production stages, connecting mobile robots and autonomous transport vehicles, as well as localization and tracking of assets. However, different technologies significantly differ in performance and capabilities, none being capable to support all industrial use cases. When designing a network solution, one must be aware of the capabilities and the trade-offs that prospective technologies have.
Which IoT communication technologies are suited for the control of industrial processes? (20min)
Eli De Poorter / Jeroen Hoebeke / Amina Sefaragic, imec-IDLab-UGent
In this first part, we will discuss technologies potentially suitable for Industrial Wireless Sensor and Actuator Networks covering an entire industrial site with limited infrastructure cost and consider their trade-offs in an effort to provide information for choosing the most suitable technology for the use case of interest. Further, it will zoom in on the ability of IEEE 802.11ah (Wi-Fi HaLow) to support control loops.
Low-latency multi-hop routing in IEEE 802.15.4e (20min)
Glenn Daneels, imec-IDLab-UA
In the second part, we will present a short introduction to the recurrent low-latency scheduling function (ReSF) for IEEE 802.15.4e TSCH sensor networks that daisy-chains resources towards the sink to minimise latency and only activates these resources when sensor data is expected to minimise energy consumption.
|10h50||Over-the-Air Software Updates in the Internet-of-Things: An Overview of Key Principles|
Jan Bauwens, IDLab-Gent
Which IoT connectivity standards are suited for over-the-air SW updates? The focus will be on system-level requirements and implementation aspects. We will explain which SW parameters can/should be updated, and illustrate the impact on energy-consumption (for battery-powered devices).
|11h10||Time for coffee – short break|

|12h15||Time for lunch|
|13h00||OPTIMIZING THE PERFORMANCE OF NB-IoT NETWORKS|
Narrowband Internet of Things (NB-IoT) is a new LTE technology released by 3GPP. The primary goals of NB-IoT are improved coverage, massive capacity, low cost, and long battery life. In order to improve coverage, NB-IoT has promising solutions, such as increasing transmission repetitions, decreasing bandwidth, and adapting the Modulation and Coding Scheme (MCS).
Coverage enhancement of NB-IoT networks, and interference classification (20min)
Guido Dolmans, Scientific Director at imec-NL, and Professor, TU/e
In the first part of the presentation, we will present an implementation of coverage enhancement features of NB-IoT in NS-3, an end-to-end network simulator. Resource allocation and link adaptation are modified to comply with new features of NB-IoT, with the goal to improve network reliability and latency. The results show that the proposed algorithm for link adaptation is 8x faster than an exhaustive search approach and yields similar latency.
We further focuses on interference classification, with having in mind that cellular technologies are expected to move to unlicensed spectrum in the near future. NS3 network predictions of LTE/WiFi and LTE/LoRa interference scenarios give insights in potential mitigation solutions.
Modelling and optimizing the energy-latency trade-off in NB-IoT (15min)
Ashish Sultania, Researcher, IDLab-Antwerp
In the second part, we will discuss two novel techniques that have been introduced by NB-IoT to optimize the energy-latency trade-off, namely extended Discontinuous Reception (eDRX) and Power Saving Mode (PSM). The User Equipment (UE) is free to configure the different eDRX and PSM parameters. However, different configurations can lead to vastly different energy consumption and DL latency. Thus, considering different IoT use cases, the optimal parameters need to be calculated. We will present our insights into proper configuration of these NB-IoT parameters for a variety of use cases.
|13h35||Combining multiple LPWAN technologies in IoT devices for seamless connectivity|
Jeroen Hoebeke, Professor, IDLab-Gent
Combining multiple LPWAN technologies – e.g. Sigfox, LoRa, Dash7,… – into one IoT product can be a good strategy to ensure the best possible connectivity, with the lowest possible energy consumption, in diverse operating conditions. Even over-the-air software updates can be possible.
In this presentation we will discuss the trade-offs between overhead and benefits to support multiple technologies.
|14h00||End of the workshop|
|List of demos in the virtual lobby|
Demo 1: IoT Enabled Greenhouses – Changing Agriculture !
Internet of Things (IoT) is shaping different aspects of Precision agriculture (PA) and coherent management strategies. This is achieved by monitoring different environmental conditions to achieve provision for adequate nutrients and effective control over pests and diseases. Mostly, greenhouses have complex topography and range of dynamic weather conditions which all impacts the IoT coverage, performance and network connectivity. This demo be all about – How IoT can feed the planet through connected greenhouses? It will feature the energy efficient sensor network and suitable wireless communication technology; along with underlying IoT deployment challenges in the context of greenhouses.
Demo 2: Modelling and optimizing the energy-latency trade-off in NB-IoT
NB-IoT introduces two novel energy saving techniques namely extended Discontinuous Reception (eDRX) and Power Saving Mode (PSM). The User Equipment (UE) is free to configure the different eDRX and PSM parameters. However, different configurations can lead to vastly different energy consumption and DL latency. Thus, considering different IoT use cases, the optimal parameters need to be calculated. In this work, we determined and analysed the set of Pareto optimal solutions, which lead to insights into proper configuration of these NB-IoT parameters for a variety of use cases.
Demo 3: IoT-fueled innovation for diverse use cases: a tailored approach
KU Leuven – DraMCo
A plethora of wireless technologies to provide connectivity for IoT applications exists and is emerging. They offer different service levels in terms of data rate, range, latency, …Links can be deployed ad-hoc or in operator-established networks. We adopt a use case tailored-approach for the selection and integration of a fit wireless technology.
We will demonstrate for the following two selected use cases, and provide illustrations for others.
1. Smart lock for MOBIT sharing bikes integrating multi-mode cellular systems (incl. NB-IoT)
2. ‘IoTrailer’ project in EU-IoF2020: Authenticated food delivery leveraging on LoRa point2point connectivity

Demo 4: Repeatability – the challenge of wireless testing
It’s hard to find a clean, controlled and realistic environment to test OTA and impossible to get repeatable test results. octoBox is a small stackable semi-anechoic personal testbed used for testing wireless devices and systems, including phones, access points, sensors and other such devices. It isolates the devices under test from the outside interference and creates a stable environment for achieving repeatable measurements. Inside the octoBox personal testbed you can emulate real life conditions, including path loss, multipath and interference.
Demo 5: Smart waste management with BrighterBins
SmartEnds and Telenet
Today 4000 BrighterBins devices have been installed in 10 countries. We discuss and compare our Sigfox vs LoRa vs NBIoT devices. We share our experience with the deployment of these devices.
|IDEAL-IoT workshop (access to user committee members only)|
On Tuesday 23 we will provide a more in depth overview of research innovations in the domain of LPWA connectivity, obtained by the partners imec, UA and UGent in the FWO SBO-project IDEAL-IoT.
