Title:
Trusted Wireless Monitoring based on Distributed Ledgers over NB-IoT Connectivity

Abstract: 
The data collected from IoT devices on various emissions or pollution can have significant economic value for stakeholders.

This makes it prone to abuse or tampering and brings forward the need to integrate IoT with a DLT to collect, store, and protect the IoT data. However, the DLT brings additional overhead to the frugal IoT connectivity and symmetrizes the IoT traffic, thus changing the usual assumption that IoT is uplink-oriented. 

In this talk, we introduce a platform that integrates DLTs with a monitoring system based on NB-IoT which is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services.

We evaluate the performance and discuss the trade-off in two realistic use-cases: data authorization and real-time monitoring.

Finally, we discuss the open challenges and opportunities of DLT-based IoT systems.
