Autonomous Management of Intelligent Home
Punčochářová, Pavlína ; Viktorin, Jan (referee) ; Korček, Pavol (advisor)
Currently, the topic of smart home is not new and there are many solutions for this problem on a market. Emphasis is placed on miniaturization of the individual elements of an intelligent system and control logic of the system as a whole. This is associated with requirement for ensuring management capabilities of the system in case of failure of the connection between some of the functional elements and the control member. This work deals with design and implementation of modifications in intelligent home gateway in an existing BeeeOn project to ensure its autonomy even in case of loss of internet connection. The problem of loss of ability to manage the household is solved by adding the possibility to establish direct communication with the gateway and the introduce automation ability into gates to control household without the participation of the controlling member. This extension brings autonomy into the system and allows user to have the household under control even in case of loss of internet connection. It leads to increase system security and quality of service in general.

Control system for cantilever gates
Koždoň, Ondřej ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The goal of this bachelor's thesis is to design a battery powered control system for wireless controlling swing gate (may be used for cantilever sliding gates or garage doors). This system is designed as a small electronic system with necessary Inputs/Outputs (I/O) and an Input for charging a battery from solar cells. The result of this bachelor's thesis are two main PCBs with dimensions of 5×5cm for controlling the gate and remote controller with dimensions of 2,3×4,4cm. Main PCB allows adding more remotes, deleting all remotes and modes for the way of controlling the gate (opposite direction, open only, close only, open wing, close wing, stop the gate) and selecting Master/Slave gate. Communication works on frequency of 434MHz.

Design and Performance Analysis of Parallel Processing of SRTP Packets
Wozniak, Jan ; Zbořil, František (referee) ; Jurnečka, Peter (advisor)
Šifrování multimediálních datových přenosů v reálném čase je jednou z úloh telekomunikační infrastruktury pro dosažení nezbytné úrovně zabezpečení. Rychlost provedení šifrovacího algoritmu může hrát klíčovou roli ve velikosti zpoždění jednotlivých paketů a proto je tento úkol zajímavým z hlediska optimalizačních metod. Tato práce se zaměřuje na možnosti paralelizace zpracování SRTP pro účely telefonní ústředny s využitím OpenCL frameworku a následnou analýzu potenciálního zlepšení.

Signalling gateway for videoconferencing
Seifert, David ; Číka, Petr (referee) ; Zukal, Martin (advisor)
Generally, the term gateway (gateway) in computer networks holds a node that connects two networks with different protocols. This thesis deals with the translation between two protocols, SIP protocol and WebSocket. This translation is the work first described theoretically and then work deals with the way this translation solutions using tools available on the Internet.

Foundation Fieldbus peripheries
Ferjančič, Michal ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
Master’s thesis deals be occupied with the transmission of process data with peripheries to control devices. Data transmission with performs through two types of industrial networks. Use with these two Foundation Fieldbus and EtherNet / IP. In work is shows method conversion through gateway between the two networks. Here there is adduced method to connected and configure devices on the networks and also their implementation. Part of this work is also creating a visualization of these peripherals and the gateway. The work is also presents possible use for laboratory task to practice.
