Contiki NTP Client
Luštický, Josef ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
This BSc Thesis was performed during a study stay at the RheinMain University of Applied Sciences in Wiesbaden, Germany. The purpose of this thesis is to describe the operating system Contiki for embedded systems, NTP time synchronisation protocol and to design and implement an NTP client for the Contiki operating system.

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.

Web-based data collection in Wireless Sensor Networks
Velký, Petr ; Komosný, Dan (referee) ; Červenka, Vladimír (advisor)
This thesis deals with the feasibility collecting data from web servers running on the nodes in sensor networks. It focuses on sensor network based on IEEE 802.15.4 and 6LoWPAN. The work itself is divided to the node side and server side.REST web services on the node‘s Web server provides sensor data. These data are collected with Java application running on the sensor network server. This servers stores collected data in a database.
