Because of the considerable technological advances in the telecommunications and fabrication sectors buying the most various sensors became a bargain sale in the last few years. The mobile industry played an important role in this process. The smart pho-nes were the very first devices, that heavily relied on the uninterrupted, smooth internet connection. This effect has spread amazingly fast in the world of information techno-logy and telecommunication. The software giants realized soon, that they needed to rebuild their politics and had to concentrate on services and devices instead of deli-verable products. This way they can reach a larger audience, because these e-contents can be consumed from pc-s, from tablets and even from smartphones. As a result, a huge process emerged with great emphasis placed upon connecting devices to the internet. The first Raspberry PI was presented in 2012, which was a small, credit card sized cheap personal computer. The story of Raspberry PI illustrates the contemporary trend the propagation of the „Internet of Things” (IoT) well.
The goal of my thesis is to build an IoT platform which enables to provide loca-tion-based services in indoor environments. Determining location in indoor is special, because most of the long standing tools and recipes which we have been using for years outdoor, such as GPS are not working due to the wall’s shielding effect. That is why completely new tools and practices are needed. It is essential to create the application by the alternative use of existing wireless technologies (such as Bluetooth and WiFi) and their cooperation.
During my work I used open source softwares and hardwares. My goal was to create a simple, lightweight, cheap and extendible platform which can be easily integ-rated with other systems.
During the development my aim was to keep the software maintainable, exten-dible and testable to ensure the quality requirements.
