Táto práca sa venuje probému prepojovania rôznych typov sietí, konkrétne sietí typu IEEE 802.15.4 a Ethernetu. Motivácia vychádza zo stále sa rozširujúceho využitia bezdrátových senzorických sietí, potreby zberu dát z nich a ich integrácie. To vyžaduje aby sieť obsahovala prvky schopné preniesť dáta z bezdrátovej siete do okolitého sveta a prípadne poskytnúť konfiguračné a riadiace informácie do vnútra siete. Z hľadiska protokolov a programového vybavenia sa prepojenie uskutočňuje na rôznej úrovni, od sieťovej až po aplikačnú vrstvu komunikačného modelu ISO/OSI, s podporou hardvéru na fyzickej a linkovej vrstve.

The main goals of diploma thesis are application and realization of tool for projection and installation wireless networks according to IEEE802.15.4. The thesis is specialized in construction of transmitter and receiver device in term of mobility and visualization of data measured in terrain. Than the software support for measuring and control appropriate periphery are summarised and described. The system is defined in C programming language and uses OpenMAC library. Last part of thesis is focus on practical measurement and testing tool for projection and installation wireless network.

Improvement of wireless technologies is a natural consequence of the progress in the field of science and technology. Usage of wireless networks based on the ZigBee technology, which are capable of indepent operation in present form, providing detailed information about physical environment and process management, brings many advantages. On the other hand, there is a serious issue about commissioning. This Master's Thesis deals with introduction of ZigBee technology and its usage, describes issue about device commissioning and types of commissioning. The main part of the Thesis is my own proposal for solving this problem, proposing algorithm using the Bitcloud stack for Coordinator, End Device and Router and its demonstration at the application. Along with analysing the application there are described possible solutions for creating a new network, adding a new node into the existing network and changing a node. The result is a graphical application and firmware for each device. The result of succesfully associated devices in network is supported by the measurement.

Master's thesis designs a device for monitoring of electric energy consumption with ability to send measured data wirelessly using ZigBee technology. Theoretical part describes basic principles for measuring electric power and energy and also a possibility of digital measurement. Thesis provides short overview of already existing solutions for electric consumption measurement available on the market as well. Further the ZigBee standard is described together with one of its software implementations named BitCloud from Atmel Corporation. Design of the device deals with the selection of suitable integrated circuit for the consumption measurement and optimal voltage and current sensors. Then also its connection with the wireless module named ZigBee using SPI bus, power supply for the entire device and also the design of PCB. There is also a firmware implementation for the designed device based on BitCloud. Description of the firmware together with calibration process implemented is also part of the thesis. Finally, basic device testing and packet analysis of communication between designed device and ZigBee network coordinator is described.

This diploma thesis describes the standard IEEE802.15.4 and Zigbee for wireless sensor networks. These norms are described in detail in the first two chapters. The main priority of the wireless sensor networks is to minimize the power of the devices and the price while maximizing the reliability of the data transfer. Minimum consumption is provided by the significantly lowered complexity in comparison to the standard wireless networks. Further, the design of the concept of the complex and universal hardware platform focused on intelligent building is described. Software implementation of those norms is described in the chapters five and six. Finally, comparison of the designed hardware platform and the other commercial platforms is described in the last chapter.

The aim of this master’s thesis is analysis of wireless communication between mikroprocesors. The first part of the work are analysed the problems the wireless free ISM band. Mainly RFM12B and ZigBee module, which i these band work and ZigBee standart. The second part are described relazation board for both module. Further how programming ZigBee module. And at last programs for tested module.
