Problem description: | In future Internet of Things (IoT) based systems a huge amount of data will be available, not only from these sensor systems, but also from the machine readable Web. The objective of this thesis is to establish a sensor platform, which will contribute to decision making. Such decision making might be part of business modelling, or simply a support system for users in context-aware situations. The selected scenario is based on eHealth, with a home-supporting system. |

Alternative Scenario
We are using an extended scenario from Dave, addressing the eHealth at home. We'd like to focus on positive monitoring, e.g. finding out if someone has not left the bed (sleeping room) or might have fallen in the bathroom. We will use sensor information for tracking people, typically in form of the position API from Android and some extra sensor information, e.g. WLAN field strength or infrared surveillance.
These data are collected and made available through the Telenor Objects (machine to machine - M2M) platform Shepherd. On top of the platform we will build an application, which uses decision making tools to inform other people.
Typical run-through with challenges
- sensors collecting data, (e.g. mobile phone position, Bluetooth 4.0 sensors)
- data collection into Telenor Objects (Master Yen)
- build an application platform using Telenor Objects data
- building the decision engine for "information"
- display results as an Android app
Collaboration with external partners
EU nSHIELD (and pSHIELD) project, where we have deployed a sensor platform consisting of:
- see pSHIELD-JBV-demo for detailed description of components
- micro platform has: accelerometer, temperature, light + GPS position + time stamp
- iPhone has: accelerometer (not used), position
Academic challenge:
- idea about the security of a system, including an analysis of threats (attacks), mechanisms to protect (encryption) and system view (integration of components)
Telenor Objects
- Telenor Objects has a focus on health care and tracking of people
- they are provider of the Shepherd platform
- talk to Juan Carlos Lopez Calvet for examples
- existing sensor systems -> deliver data to Telenor Objects -> inform people
- Challenge: "trust-based privacy"
UiA and InnoMed.no
- Dave Dafferianto.Trinugroho has developed the scenario, described in Media:Dave-eHealth-Scenario.pdf
- he has also created the first .owl (ontology description for the home scenario)
- check InnoMed for scenarios and other partners being involved
- Invite yourself to seminars (17. january 2012, ...)
others
sensor comparison - various sensors to be integrated
- Bluetooth 4.0 sensors (Mobile Phone, MacMini,...)
- TiniDB and esper (complex event processing) -> algorithms to establish
- Sensors in home-care systems (what happens in an environment)
