New Mobility Trends in Data Networks
 Skořepa, Michal ; Róka, Rastislav (oponent) ; Bešťák, Robert (oponent) ; Koton, Jaroslav (vedoucí práce)
The doctoral thesis is focused on a design of novel Mobile IPv6 handover strategy suitable for deployment in aeronautical data networks. The current handover strategies provide sufficient performance in the conventional ground networks such as WiFi or UMTS that dispose high bandwidth and low latency. However, as this thesis shows, deploying these handover strategies in aeronautical data link environment does not bring desired benefits - the handover latency is high and the related overhead gets high as well. The novel MIPv6 handover strategy presented in this thesis is based on a simple thought: ''I am an aircraft, I know where I'm flying!'' This means that the movement of the aircraft is not random, it is highly predictable. Thanks to that, inter-network handovers may be anticipated and necessary IP handover related actions can be taken in advance, while the aircraft is connected via a broadband ground link at the origination airport. The thesis also presents a comparison of the existing handover strategies with the proposed new one conducted using an analytical approach. This allows to quantify the benefits of the novel handover strategy and the drawbacks of the current ones.
