Model of computer network in MATLAB/SIMULINK environment
Zedníček, Petr ; Zeman, Václav (referee) ; Kolka, Zdeněk (advisor)
The bachelor thesis deals with simulation of TCP protocol behaviour in Wireless optical environment. The thesis examines the various parameters of the protocol and evaluates their response to the transmission speed. The key objectives of the thesis are the introduction to the problems of communication, specially the description of the transport layer architecture, TCP / IP and congestion management mechanism NewReno. A large part of the thesis is devoted to modelling communication points and a model of optical wireless connections. The results will be applicable to create a new communication protocol for Wireless optical environment.

Analysis of the effect of delay and window size on TCP connection efficiency
Kavický, Martin ; Komosný, Dan (referee) ; Molnár, Karol (advisor)
Content of master’s thesis is description field of Sliding window and it’s expansion algorithms, witch are Slow start, Congestion avoidance, Fast Retransmit and Fast Recovery algorithm. Thereinafter is described creation of model in Opnet Modeler’s simulation area. In this simulation area was analyzed reactions of average transfer speed onto variance of data size, lost ratio, latency in short and long time slot and variance of receiver’s buffer size. In last section of this document is method design witch makes it possible of transfer speed control through the use of receiver’s buffer size dynamic setting.
