Problem description: | The Norwegian Institute for Air Pollution monitoring has initiated the project CITI-SENSE-MOB on Mobile Air Pollution measurements. Mobile sensor platforms are going to be installed on buses, cars and bicycles to achieve a wider distribution of measurements, as compared to the limited number of fixed stations.
The goal of this thesis is to establish the semantic framework for sensor integration on a global scale. GEOS, the framework for creating a community-driven interoperable geoscience-wide geoinformatics infrastructure, is seen as one of the key candidates for sensor integration and sensor fusion. The expected outcome of the thesis is an integration framework for mobile sensor data, based on semantic technologies. A semantic rule system is envisaged to control the reliability of the sensor system, either as a stand-alone evaluation on the sensor platform, or as a fusion of sensor. Such a fusion might consist of mobile data together with sensor data from other sources, e.g. the fixed air quality stations in order to establish models for reliability. |
Methods and Tools: | The tools and methods in this thesis are based on
|
Time schedule | The envisaged time schedule (for a long thesis/60 ECTS) is:
|
Pre-Knowledge | This thesis includes a reasonable amount of programming. The envisaged thesis is based on radio communications, thus expects the user to have followed at least two radio-related courses |

Next steps
- decide on long or short thesis
- learn about semantic technologies (e.g. UNIK4710, Logic group, ...)
- start writing a scenario: think about an idea on how sensors can deliver reliable results
- GEOS (Arne J Berre and the other Sintef students)
- ...

Comments
Red line
Your thesis should have a "red line", which is visible throughout the whole thesis. This means you should mention in the beginning of each chapter how the chapter contributes to the "goals of the thesis".
Use of scientific methods
A thesis follows a standard method:
- describe the problem (problemstilling)
- extract the challenges. These challenges should be measurable, e.g. method is too slow to be useful to voice handover.
- Analyse technology with respect to challenges. Don't write & repeat "everything" from a certain technology, concentrate on those parts (e.g. protocols) which are of importance for your problem
References
- Wikipedia is good to use to get an overview on what is happening. But there is not scientific verification of Wikipedia, thus you should use wikipedia only in the introduction of a chapter (if you use text from wikipedia). Use scientific literature for your thesis.
- Scientific library is "at your hand", you can get there directly from UiO: [[How to get access to IEEE, Springer and other scientific literature -> Unik/UiOLibrary]]
- I suggest that references to web pages, e.g. OASIS, W3C standards, are given in a footnote. Only if you find white papers or other .pdf documents on a web page then you refer to them in the reference section.
Evaluation of own work
Perform an evaluation of your own work. Revisit the challenges and discuss in how you fulfilled them. Provide alternative solution and discuss what should be done (or what could have been done).
