Mobile Agents in Wireless Sensor Networks
Spáčil, Pavel ; Kočí, Radek (referee) ; Zbořil, František (advisor)
The aim of this work is to describe platform's concept and interpreter's implementation for mobile agents in wireless sensor networks. The reader will meet with theoretic and practical respect - he will obtain information about simple operating system TinyOS used for Motes' programming, about nesC language and about intelligent agents. Then he will meet with agents' language ALLL. Its semantic is illustrated on clear examples. The platform's concept and the concrete ALLL interpreter implementation will be described. Some examples with detailed description mustn't be missing at the end.

Agent-Based Monitoring of Wireless Sensor Networks
Houšť, Marek ; Kočí, Radek (referee) ; Zbořil, František (advisor)
The reader is first introduced with history and possible applications for wireless sensor networks. The thesis then describes the problems of wireless sensor networks and implementation tools for wireless sensor networks. The thesis also presents the system WSageNt and its client web interface. Practical part is based on the design of agent elements. Describes gradual implementation, testing and practical realization of these agent elements in the system WSageNt. The final part discusses the advantages and disadvantages of the project and identifies possible future expansion of the system.

Platform for Mobile Agents in Wireless Sensor Networks
Horáček, Jan ; Kočí, Radek (referee) ; Zbořil, František (advisor)
This work deals with implementation of an agent platform, which is able to run agent code in wireless sensor networks. Implementation has been done for MICAz platform, which uses TinyOS operating system for developing applications. This work contains list of chosen TinyOS parts and illustrates, how such a platform can be used for our purposes. We will describe main features of ALLL language and we will also demonstrate some examples of agents.

Basestation for WSageNt Agent Platform with Using GSM Module
Molák, Josef ; Rozman, Jaroslav (referee) ; Horáček, Jan (advisor)
This master's thesis describes the software and hardware extension of multiagent platform WSageNt to ensure communication between basestation and web interface Control Panel using GSM network. Sensor node FITmote is used as a basestation and modem Teltonika is used as a interface to GSM. The physical interconnection of the devices implementing the newly created bridge to connect different logic voltage levels of their serial interface. Application for basestation was extended to serial communication with modem. This extend provide communication over GSM network to Internet. Application on control server also was modified for TCP/IP communication.

Wireless Sensor Network for Building Monitoring with Partially Dynamic Topology
Urbanovský, Jiří ; Zbořil, František (referee) ; Samek, Jan (advisor)
This thesis describes the possibilities of wireless sensor networks in monitoring buildings and summarizes the most common use of wireless sensor networks in practice. There are also described communication protocols needed for communication between each node and properties of topology of created network. Importance is lay on implementation of fully dynamic network with automatic network topology establishment. The application is designed for the TinyOS operating system and hardware platforms MICAz and IRIS, and its task is to establish the topology and send the data obtained from sensors to base station. The implemented protocol is based on the Collection Tree Protocol protocol and using best effort delivery is able to establish a dynamic topology. Further there is described the method of storage and subsequent graphical and textual representation of data collected.

Sensor Modules for ZigBee Wireless Network
Ochmann, Tomáš ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to design and implement modules for wireless sensor network ZigBee. These modules could communicate together and share information about measured values. The network will be managed by coordinator of network, which will process data from sensor modules and will decide about next steps around the network.

Intelligent Sensory Net designed on the standard IEEE 802.15.4
Janšta, Tomáš ; Holý, Miroslav (referee) ; Matoušek, Radomil (advisor)
This thesis focuses on design of wireless network nodes using modular construction parts with respect to IEEEŽ 802.15.4 standard. Presented platform joins the benefits of the XBeeŽ wireless module and the AVR ATmega128 microcontroller development system. Sensor network prototype is designed to meet the desired first attempt functionality of embedded platform for collection and delivery of small volumes of control and sensor data between the network and the gateway. The control software was developed for TinyOS operating system. Designed platform is used as the framework for future development and possible functionality extensions in related applications.

Distance Estimation in Wireless Ad-hoc Network
Botta, Miroslav ; Mráz, Ľubomír (referee) ; Šimek, Milan (advisor)
The work deals with processing of radio received signal strength in IEEE 802.15.4 which communicates in 2.4 GHz ISM band. The signal is processed by the three approximation methods. They are tested for their effectiveness for measuring in different radio environments. Furthermore, the work deals with calculation of the most efficient coefficients for distance calculating by radio transmission fucntions. It defines the issues of such solutions on practical examples. The work also deals with the experimental algorithm for implementing dynamic calibration of the coefficients. It describes the design, processing and verification of this system in practice.

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.
