Home Security and Monitoring System
Valach, Lukáš ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The thesis elaborates on an implementation of wireless home security system. The wireless communication utilizes IEEE 802.15.4 radios and ZigBee communication protocol. The beginning of the thesis provides specification of the intended system followed by an evaluation of usable energy harvesting solutions and later by consideration of single board computer systems suitable for implementation of the control node of the sensor network. The rest of the thesis describes design, implementation and testing of particular components of the security system. Conclusion evaluates the achieved goals and offers suggestions for future work. The end products of the thesis are physical devices implementing wireless sensor nodes, control unit of the security system as well as a graphical user interface for the system management.

Wireless Sensor Network with Atmel AVR Microcontrollers.
Mráz, Ľubomír ; Kouřil, Jiří (referee) ; Šimek, Milan (advisor)
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.

ZigBee in Building Automation
Liška, Radovan ; Šimek, Milan (referee) ; Honzík, Petr (advisor)
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.

Zigbee node for monitoring of electric energy consumption
Štefany, Martin ; Mráz, Ľubomír (referee) ; Šimek, Milan (advisor)
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.

Wireless sensor network configuration
Minár, Tomáš ; Botta, Miroslav (referee) ; Morávek, Patrik (advisor)
This bachelor’s thesis is dedicated to wireless sensor networks in terms of energy consumption of operating systems. Requirements and configuration principals to assure low energy consumption and effectiveness of sensor nodes are discussed in more detail. This document should serve as an introduction to wireless sensor networks and provide a reader with information about commonly used standards, their differences and field of application. Three most widely used operating systems: TinyOS, Contiki and BitCloud are described and used in practical experiments. The practical part deals with configuration of IRIS sensor node in those operating systems. This part compares the influence of different configurations on energy consumption.
