Ad Hoc Network Scenarios and Different Types of Attacks
Rexa, Denis ; Kenyeres, Martin (oponent) ; Škorpil, Vladislav (vedoucí práce)
In this semester thesis dedicated to MANET networks and security threats are compared the routing protocols AODV vs OLSR vs ZRP. Next chapter is dealing with a broadcast storm and discussed in more detail basic types of attacks in MANET networks with proposals to suppress the impact on the functioning of the network. In the next chapter, it is shown and described an environment of NS-3 simulator with that program and simple way how to reach the information. The last chapter shows the influence of black-hole attack on the network, and a proposal for its elimination.

Computational tasks for solving parallel data processing
Rexa, Denis ; Uher, Václav (oponent) ; Mašek, Jan (vedoucí práce)
The goal of this diploma thesis was to create four laboratory exercises for the subject "Parallel Data Processing", where students will try on the options and capabilities of Apache Spark as a parallel computing platform. The work also includes basic setup and use of Apache Kafka technology and NoSQL Apache Cassandra database. The other two lab assignments focus on working with a Travelling Salesman Problem. The first lab was designed to demonstrate the difficulty of a task where the student will face an exponential increase in complexity. The second task consists of an optimization algorithm to solve the problem in cluster. This algorithm is subjected to performance measurements in clusters. The conclusion of the thesis contains recommendations for optimization as well as comparison of running with different number of computing devices.
