Abstract:
Constant advances in mobility, towards more efficient, sustainable and user-centered model, are pushing forward the concept of what we understand for transport and solving everyday issues through intelligence services and smart devices. This involves changes on all the value chain, but specially on transport centers.

Abstract:
Multiple Radio Access Technology (multi-RAT) communication with Low Power WideArea Networks (LPWAN) significantly increases the flexibility of Internet of Things (IoT) applications.Location-based services that build upon such a multimodal communication architecture are ableto switch to an optimal localization method depending on the constraints of the active wirelesstechnology. Furthermore, the resulting location estimate can aid location-based handover mechanismsto reduce the energy consumption of a multi-RAT IoT device. In this research, we present our designof a multimodal localization framework and illustrate the benefit of such a framework with twoIoT use case examples. For the first use case, valuable artwork is tracked during transportation toa museum. In the second use case, we monitor the usage and location of large construction tools.Finally, we propose how our localization framework can be improved to deal with implementationchallenges and to reduce location estimation errors.

A Multimodal Localization Framework Design for IoT Applications

Abstract:
Internet of Things (IoT) technologies, when adequately integrated, cater for logistics optimisation and operations’ environmental impact monitoring, both key aspects for today’s EU ports management. This article presents Obelisk, a scalable and multi‐tenant cloud‐based IoT integration platform used in the EU H2020 PortForward project. The landscape of IoT protocols being particularly fragmented, the first role of Obelisk is to provide uniform access to data originating from a myriad of devices and protocols. Interoperability is achieved through adapters that provide flexibility and evolvability in protocol and format mapping. Additionally, due to ports operating in a hub model with various interacting actors, a second role of Obelisk is to secure access to data. This is achieved through encryption and isolation for data transport and processing, respectively, while user access control is ensured through authentication and authorisation standards. Finally, as ports IoTisation will further evolve, a third need for Obelisk is to scale with the data volumes it must ingest and process. Platform scalability is achieved by means of a reactive micro‐services based design. Those three essential characteristics are detailed in this article with a specific focus on how to achieve IoT data platform scalability. By means of an air quality monitoring use‐case deployed in the city of Antwerp, the scalability of the platform is evaluated. The evaluation shows that the proposed reactive micro‐service based design allows for horizontal scaling of the platform as well as for logarithmic time complexity of its service time.

Design and evaluation of a scalable Internet of Things
backend for smart ports

Abstract:
Due to the limited bandwidth of Low-Power Wide-Area Networks (LPWAN), the application layer is currently often tied straight above the link layer, limiting the evolution of sensor networks distributed over a large area. Consequently, the highly efficient Static Context Header Compression (SCHC) standard was introduced, where devices can compress the IPv6 and upper layer protocols down to a single byte. This approach, however, assumes that every compression context is distributed before deployment, again limiting the evolution of such networks. Therefore, this paper presents two context registration mechanisms leveraging on the SCHC adaptation layer. This is done by analyzing current registration solutions in order to find limitations and optimizations with regard to very constrained networks. Both solutions and the current State-of-The-Art (SoTA) are evaluated in a Lightweight Machine to Machine (LwM2M) environment. In such situation, both developed solutions decrease the energy consumption already after 25 transmissions, compared with the current SoTA. Furthermore, simulations show that Long Range (LoRa) devices still have a 80% chance to successfully complete the registration flow in a network with a 50% Packet Error Ratio. Briefly, the work presented in this paper delivers bootstrapping tools to constrained, SCHC-enabled networks while still being able to reduce energy consumption.
