Mobility management in IP networks is considered a core technology in
modern network environments, since more and more communication networks
move towards all IP networks. Mobile IP provides transparent user
mobility in the network layer. This thesis presents a simulative comparison
of standard Mobile IPv6, a fairly new Internet Standard, and four proposed
enhancements, i.e., Hierarchical Mobile IPv6, Fast Handovers for Mobile
IPv6, a combination of them and finally Fast Router Advertisements using
a modified version of the network simulator ns-2. To accomplish realistic
simulation results two different "hot spot" scenario, comprising up to
nine access routers and 70 mobile nodes, utilizing the IEEE 802.11 wireless
standard, are designed. The simulative study provides an overview of
Mobile IPv6 protocol performance with respect to handoff latency, packet
losses and channel utilization in case of and without Route Optimization.
Furthermore, the study analyses the effect of the proposed Mobile IPv6
enhancements on performance aspects by observing a single mobile node
influenced by a number of randomly moving nodes. By using ns-2, simulation
results could be achieved for different types of traffic, such as constant
bitrate UDP, Voice over IP, Video and TCP. In order to complete the study,
the thesis analyses the effect of number of correspondent nodes and handoff
rate on the signaling load.
