The aim of this thesis is to design universal sensoric platform for data collection in manufacturing environment. Device is capable of collecting data from variety of sensors, but it is also able to control external systems. Platform is controled by Lua scripts. The scripts are generated in user friendly visual programming environment Blockly. Platform is based on WiFi module ESP-WROOM-02.

This diploma thesis describes implementation of an indoor positioning system for tracking the location and movement of material and products through the manufacturing plant. The system is designed with regards to simple installation and low overall implementation costs. It utilizes method of Wi-Fi and magnetic field fingerprinting. The system employs a client hardware (active tag with Wi-Fi module and sensors designed for this project) communicating with a server software which does the mapping and fingerprinting processing. Finall positioning system is prepared to collect locations data for further analysis aiming to improve efficiency of manufacturing processes.

This work describes security mechanisms of wireless network based on 802.11 standard and security enhancement 802.11i of these networks known as WPA2, where the analysis of vulnerabilities and attacks on these networks were performed. The work discusses two major security issues. The first is unsecure management frames responsible for vulnerability with direct impact on availability and the other is the vulnerability that allows executing the impersonalize type of attacks. The system for generation attacks was designed to realize any attack very fast and efficient. The core of the thesis is the design of a system for attack analysis using the principle of trust and reputation computation. The conclusion of the work is devoted to experimenting with the proposed system, especially with the selection of suitable metrics for calculating the trust value.

This work deals with design of PC remote control, which is able to control computer with operating system Windows and Linux using Wifi connection. There was also created necessary support software for both operating systems. Communication was secured by ciphering algorithm.

This thesis deals with implementation of a wireless interface for a module providing communication between computer and electronic control unit of an automobile. The 802.11 standard, wireless network structures and MAC sublayer were described. The thesis suggests selection of the most suitable WLAN module, testing of module's features used and the WLAN module implementation. Modifications for the next device version were developed and programs for device operation were implemented.

The main aim of this master's thesis was the create function models of wireless network technologies using the modern multitones modulation like is PFDM and FMT. This work is realised in Matlab – Simulink enviroment and models are tested in development kit. Development kit is universal software defined radio developer by Ettus.

This master‘s thesis deals with applications for tablets running Android to control the car. As a control unit is used Raspberry Pi with Edimax WiFi module. The practical part focuses on the realization of applications for tablet and board layout for switching lights.

The master work is focused on the design and implementation of two parts of the system for measuring temperature and relative humidity. The system for measuring temperature and relative humidity consists of a network of wireless sensors, a ISM/Wifi converter and application which will collect, analyze and archive data. The design and implementation of ISM/Wifi converter as well as the design and implementation of application are described in this work. ISM/Wifi converter will be able to communicate with the network of wireless sensors through ISM/Wifi protocol and end device (the device with Android operating system) by means of IEEE 802.11 protocol. The application will be able to evaluate, to save and to present user the received data very clearly.

This work deals with the public data network covering of the locality of the noth-east part of Brno and neighbouring villages.

This thesis deals with the issue of locating devices in wireless networks. It takes existing solutions as example and extends them using additional approaches. This thesis designs and describes the implementation of a prototype of a new proprietary indoor localization system used for locating devices within a WiFi network. In the final part of the thesis the testing of this system is described and its results are analysed and compared with another localization systems based on similar technologies.
