Modern trends in Wi-Fi IEEE 802.11 networks security
Lieskovan, Tomáš ; Škorpil, Vladislav (referee) ; Endrle, Pavel (advisor)
This work treats the matters of wireless networks, Wi-Fi. The paper describes the various principles of coding, such as WEP, WPA and WPA2. At first the WEP security method is analyzed with the view of the fact that it doesn´t meet contemporary safety requirements, further its successor WPA, namely TKIP and AES authentication methods, and last but not least WPA2 which nowadays serve as a safety standard. The work assesses the safety risks of individual security methods and makes several recommendations to achieve maximum security for wireless networks. In the work a commercially available hardware and for free dissemination available software (Open Source) are used.

Location Estimation of Objects in WiFi Communication Network
Kohoutek, Jan ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The purpose of the thesis is to design and physically implement a system for location of devices in a Wi-Fi based networks deployed in the interior of small and medium-sized enterprises. First of all, the attention is given to the survey of commonly available technologies suitable for determination of the object position. Then, based on these findings, architecture of a location system comprising an array of sensor nodes and central processing unit is proposed. In conclusion, the results are presented and the fulfillment of the requirements is evaluated.
