Title
“Enhancing IoT Systems by Exploiting Opportunistically Collected Information from Communication Networks”

Abstract
Today Internet of Things (IoT) systems operate as cyber physical systems, meaning that the systems both have a digital and a physical context. The physical context is defined in terms of location, number of other users, signal strength and other. The digital context is defined in terms of services, network performance, and other. By knowing about these aspects of a system allows for optimization or enhancing of the system, why it is of interest to obtain and process the information.

In this work, it is investigated how different types of information related to distributed IoT systems can be obtained cost effectively by collecting them opportunistically. Specifically, two information types are collected, namely transport layer end-to-end network performance information, and people count information on public transport. It is investigated how these information types can be collected and derived based on crowd sourcing of measurements and based on passive WiFi probe collection. The network performance information is evaluated on 3G and 4G connections and the measurement methods are evaluated in terms of accuracy and efficiency. The people count is estimated based on probabilistic models. It is proposed how the collected information types could enhance an actual smart parking system.
