Usage of OSS/FS in enterprise network
Sobotka, Ondřej ; Hošek, Jiří (referee) ; Kříž, Jiří (advisor)
This bachelor's thesis describes propose and realization of a new evidence/reclaim system. It uses only software with an available source code – licensed as Open Source or Free Software. Main purposes are to streamline and simplify common processes in service department, for example inserting, printing, editing and listing of reclaims, creating reports, automatic executing of repeated operation and etc. Among other aims of this thesis rank accessing to the reclaim database via internet and application of security rules for an access to and work with system. MySQL server was chosen as the database system, as the HTTP server was chosen Apache. Programming languages HTML, CSS, JavaScript, PHP and SQL were used for development. Theoretical observation are mentioned first followed by analyzation of the former state in the service department and sumarization of found problems. Next key part contains detailed steps solving these problems and resulting benefits.

Smart Home Control by Utilizing AllJoyn Platform
Resler, Tomáš ; Kováč, Dominik (referee) ; Hošek, Jiří (advisor)
This bachelor work concerns with system Alljoyn which tries to standardize the interface for communication in the frame of intelligent house. The basic principles and the structure of the framework Alljoyn including the recent proposal of the modules Lighting framework and Gateway Agent have been described in the theoretical oriented part of the work. The practical oriented part stars with the description of the getting the Alljoyn framework including the Lighting controller and the Gateway Agent to work on the hardware router provided with operating system OpenWRT. The following parts present own testing connector for the Alljoyn Gateway which have been written to allow the remote control of the lights via cloud service Twitter. The functionality of the router have been tested with software simulator of the Alljoyn lights Luminaire and an own ligths driving program developed utilizing the experimental Lighting SDK for mobile devices with operating system Android.

Simulation of H2H and M2M Communications in Mobile Network LTE-Advanced
Číhal, Josef ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
This bachelor thesis „Simulation of H2H and M2M communication in LTE-Advanced mobile network“ focuses on theoretical study of H2H (Human to Human) and M2M (Ma- chine to Machine) communication in fourth-generation of mobile network (LTE/LTE- Advanced). It also focus on the influence of M2M communication to compliance with the agreed terms of quality of service (QoS) for H2H traffic. Based on the theoretical analysis was created model of H2H and M2M communication using NS-3(Network Si- mulator 3). Last part of bachelor thesis deals with verification of the functionality of created model through simulations focusing on the key operational parameters such as delay, throughput and load of base station (eNodeB).

Verification of the statistical reliability of simulation results in OPNET Modeler environment
Fördős, András ; Vajsar, Pavel (referee) ; Hošek, Jiří (advisor)
Project is focused to verify the credibility of the results of statistical simulation in the surround of OPNET Modeler. At the beginning of the project is a short introduction to the problematic of OPNET Modeler. It describes the basic concepts of mathematical statistics, data types and some basic statistical charakteristics. In the project was created model of LAN network, were set up three different types of runs and several monitored statistics. In this project are listed setting of the model, startup parameters of some runtime simulations, prefered variety of statistics and the possibility to display final results of statistics. Description of options displaying final results of statistics is supplemented by model characteristics. Created model was further extended and modified. Have been added network services, has changed the number of nodes and the duration of the simulation. Results of analysis of the original scenario are compared to the results of a modified scenario, which are scheduled. At the end of this project are obtained result, recommended way and form of displaying basic statistics and advice on the number of simulation runs needed to obtain reliable results.

Simulation of routing protocols in ns3 simulation environment
Masár, Marek ; Hošek, Jiří (referee) ; Vajsar, Pavel (advisor)
The first part of thesis is about networks that are divided based on area. It includes also basic characteristic of Manet networks. The next chapter is about distribution of routing protocols into preactive, reactive, hybrid. In the simulation, there is comparison of 3 routing protocols, which are described in this chapter. The simulation is performed in program called Ns-3, more specifically in version 3.14. In the third chapter, this network simulator is described more closely. Here is also mentioned its continuity on previous version Ns-2. The goal of this simulation is to create a network with implemented routing protocols and with certain number of nodes, which has configured mobility, so the network looks like Manet network as much as possible. There are also 2 applications created, which were used to determine the delay for each routing protocol. Another part of thesis is about implementation of the quality of service (QoS) and energy model for each routing protocol. Energy model was used to calculate the remaining energy of node. Next activity summarizes how the implementation of QoS changed delay for used applications and how it changed the energy consumption of a node. The result of thesis is that the voice applications was preferred after the QoS implementation. The value of delay increased for ftp application. Percentually, the improvement for voice traffic was 30-31 %. The increase of delay was percentually 7-19 %. The difference in remaining energy after QoS implementation was about 1%. The actual amount of battery in the beginning of simulation was 1 J.

Simulation of mobile ad hoc network in NS-3 environment
Kolaja, Lukáš ; Hrouza, Ondřej (referee) ; Hošek, Jiří (advisor)
The goal of this bacherlor thesis is theoretically analyze the principles of wireless mobile ad hoc networks. The thesis describes the types of routing protocols such as AODV, DSDV or OLSR. Further describes the types of mobility models which is typically used in MANET. The thesis also deals with issues like use, safety and development of mobile ad hoc networks. The goal of the practical part is create an application which can parse an XML document that generates simulation that is already created. The application is written in PHP language and output data from this application is inserted to the databse by using SQL commands. From the database is easy to read the data from the original XML document.
