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.

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.

Dynamic Memory Allocation in TinyOS
Križanský, Ján ; Zbořil, František (referee) ; Horáček, Jan (advisor)
This thesis aims for a theoretical and practical comparison of two different approaches to dynamic memory management in TinyOS operating system designated for simple programmable devices. For each of the approaches we were observing different aspects, among others the effectivity of usage of resources, allocation speed and usability from the programmers point of view. Thesis also extends the capabilities of dynamic allocation onto external flash memory. It shortly explains the principles behind dynamic memory allocation and it's application in the area of simple programmable devices with limited resources.

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.

Usage of Intelligent Agents in Wireless Sensor Networks
Žídek, Petr ; Janoušek, Vladimír (referee) ; Zbořil, František (advisor)
This thesis is focused on wireless sensor networks and implementation tools for creation and simulation of applications. It describes WSnageNt project, which is intended to support agents in wireless sensor networks. The main objective of this thesis is to extend the WSageNt project with new features that will allow to create agents with more capabilities. These features will be then used to extend the WSageNt project with network node movement tracking capability.

Wireless Sensor Network with Static Topology for Building Monitoring
Koudelka, Jan ; Žák, Jakub (referee) ; Samek, Jan (advisor)
This bachelor's thesis is focused on realization of wireless sensor network (WSN) for buildings monitoring and real-time obtaining of data. Just for work on this project the micaZ sensor nodes have been chosen. The main task is to create WSN with a static topology and some communications mechanism. That network consists of several nodes, and there is a special one called base station. It also has a special function, different from the others. The function is that the base station is collecting data from all of the nodes and sending them to a computer through an USB port. In addition to designing the network topology the other tasks are to implement a comunication protocol and to create computer application and application for sensor nodes. Data will be visualised in text and graphical form. Moreover there are some information about the simulation tool called TOSSIM which allows testing applications without having a physical access to micaZ sensor nodes.

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.
