Impact of Communication Parameters on Energy Consumption of Zigbee Devices
Popelka, Jan ; Červenka, Vladimír (referee) ; Šimek, Milan (advisor)
This thesis deals with the energy research and design a simple wireless sensor networks. The data modules with ZigBee wireless communication technology. The main feature of wireless sensor networks is the minimal energy devices at low cost and maximum data reliability. Furthermore, the work describes firmware for communicating nodes with the ability to change parameters of data transmission and thus affect the energy consumption node. Calculations of energy consumption, compared with measured results and discharge characteristics of the battery packs are included in the final chapters of this work.

Application Layer DOS Attack Generator and Protection
Juhaňák, Pavel ; Kula, Michal (referee) ; Musil, Petr (advisor)
This bachelor’s thesis is focused on generating DoS attacks and protect against them. It should introduce the reader to the problems of DoS attacks, explain their division and the basic principles of their operation to him. Furthermore, it provides methods and advices how to defend against such attacks or to prevent their occurrence. It provides a preview of the available DoS tools and their evaluation to the reader. The tool able to generate DoS attacks is designed and implemented as a part of this work. It is capable of generating HTTP GET, HTTP POST and DNS amplification attacks. The DoS tool was successfully tested during attacks on a web server Apache 2.2.21. The records and evaluation of these tests are also part of this work.
