Piškula, David ; Nosko, Svetozár (referee) ; Musil, Petr (advisor)
Internet of Things is among the newest phenomena of information technologies. This work describes the evolution and future of the Internet of Things and provides an overview of its current applications, then summarize the communication interfaces and protocols usable for the creation of the Internet of Things. The main focus is put especially on the IEEE 802.15.4 standard, 6LoWPAN protocol and the Thread technology. It also explains the term of Cloud Computing, platforms that are providing it and related types of databases. The design, implementation and testing of a Thread based solution are part of this thesis.

Data collection from sensor units
Frkal, Pavel ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This thesis deals with data collection from sensor units connected via 6LoWPAN standard (IEEE 802.15.4 standard), which uses simplified IPv6 protocol on the network layer. Featuring optimization makes this solution suitable for use in systems powered with chemical power supplies with a very low current consumption of both the sensor units and the control units. The thesis focuses on collecting data from sensor units that communicate on a star topology basis but it's also discussed possible usage of general topology, the end-station in such case works as active repeater and thus extend sensor network coverage without need of additional devices for wireless frames repeating or forwarding. It evaluates the realization of sensor networks created by both the actual data collection as well as specific technical parameters of used sensor boards. The practical part contains a specific application for gathering data from sensors present on the units and storing them in a relational database MySQL.

Location visualization of sensor units
Hulanský, Jozef ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This master thesis deals with wireless sensor network with protocol IPv6. In the begining there are explained the priciples of communication in wireless sensor network, and based on this teories are configured a wireles network with predefined development kit. Furthermore, by using geographic coordinates, positions of the nodes are displayed on a website, what is a part of this thesis. On this website are also presented the measured values from sensors. For saving all informations and measured values about each nodes was used remote MySQL server. Communication between this server and 6LoWPAN network provide Perl script which is runs at periodical intervals. With this method automatization of the whole system are ensured.

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.

IPv6 and power efficiency in Wireless Sensor Networks
Kladiva, Roman ; Šimek, Milan (referee) ; Červenka, Vladimír (advisor)
This bachelor's thesis deals with wireless sensor networks in terms of energy performance of IPv6. It contains a description of wireless sensor networks, sensor node analysis and 6LoWPAN and IPv6 protocols. The another part of the thesis is focused on adaptation layer 6LoWPAN and tools, which used to minimize the transmission unit, and thus to reduce energy consumption. Problems of energy consumption in wireless sensor networks is discribed in the thesis and its possible solutions at the physical and link layers. There are analyzed in detail possibilities of sleep mode and various MAC layer protocols are analyzed in detail. The measuremenr overview of the sensor node and own proposal to improve the measurement method are discribed following in the thesis.

IPv6 for Wireless Sensor Networks
Polak, Martin ; Komosný, Dan (referee) ; Červenka, Vladimír (advisor)
This thesis deals with the issues 6LoWPAN protokolu and implementation of IPv6 on the specied platform. Introduction thesis deals with the explanation of wireless sensor networks. Next it was descibed 6LoWPAN protocol, which maps IPv6 on standard IEEE 802.15.4. The thesis further concentrates to exploration of possible operation systems, that are designed for sensor networks and then followed by comparison of their characteristics and advantages. The fth chapter is focused on he implementation of the operating system to the sensor node Iris, introduction Iris and with the structure of the operating system Contiki OS. At the end of thesis is description of the implementation of this system in the sensor node Iris.

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.

Internet of Things Device Based on ZigBee and 6LoWPAN
Halász, Dávid ; Mlích, Jozef (referee) ; Musil, Petr (advisor)
Internet of Things is the latest phenomenon in the computing industry. Even if it has not been completely defined yet, we are already surrounded by various devices connected to the Internet. This thesis project focuses on low cost and low-power wireless solutions and on the on-line backend behind the architecture. At the same time the present work also deals with Cloud Computing which can provide a highly scalable runtime environment for this backend without building an infrastructure. To handle the huge amount of data collected by billions of devices, BigData services could be used in the same cloud space. The project is a collection of the theoretical background of the Internet of Things; so as a result, it provides the reader with an overview of the concept. It also provides a walktrough of the design, implementation and testing process of a complex agricultural Internet of Things solution.
