FruityMesh Implementation of a battery-efficient mesh network on top of Bluetooth Low Energy

This thesis introduces a mesh implementation for purely battery-powered nodes that works on top of the Bluetooth 4.1 specification and proposes the FruityMesh algorithm to solve the complicated task of autonomous meshing and maintenance. Current state-of-the-art scientific, BLE and other mesh networks are presented before discussing possibilities and limitations of Bluetooth Low Energy. A simulation …

Conception and Development of an App-Generator based on Webtechnologies

The thesis covers the automatization of the development of news-apps for mobile devices. First, the technical foundations of generative programming are explained and contrasted with conventional object-orientated programming. Using this basis, a concept for an app generator is described. The requirements are defined and possible techniques are analyzed and compared. The resulting conclusions are summarized …

Information retrieval and visualization on mobile Devices and their practical realization using semantical text analysis

Analyzing textual information using semantic methods has become a necessity in order to control the increasing amount of information and its condensed presentation on the small displays of mobile devices. A large knowledge base is a prerequisite for such algorithms. In this work, we present a new algorithm which uses the structured database Freebase and …

Conception of a web-based runtime for infotainment systems

The subject of this masterthesis is the design of a web-based runtime environment for in-car infotainment systems. It develops an architecture to speed up the deve- lopment of prospective systems without jeopardizing the security. The approach is based upon a central interface for communication. Different approaches will be evaluated in order to elaborate a specification …
