The ever-increasing Mobile Internet traffic and the growing demand of mobile users were the main reasons that have led to the creation of my thesis. Since the constant reachability while changing between different networks is a basic requirement of user satisfaction Mobil IP protocol has been brought to life. But the few central mobility management device (i.e., centralized anchor node) deployed by Mobil IP cannot cope with the increased amount of data traffic generated by the millions of moving subscribers. This is the main reason why current centralized architectures of the Mobile Internet should be abolished and to take its place new Distributed and Dynamic Mobility Management techniques should be introduced.

Since there is no unified standard yet for this purpose, in the first part of my thesis I present a set of different co-existing promising DMM technologies. After that I compare these solutions according to some predefined criteria to get a clear picture of the pros and cons of each solution. At the end of this section I describe one of the most promising techniques, namely the Route Optimization which is the main topic of my thesis.

After the introduction of the theoretical background I demonstrate two, completely different DMM methods I have implemented in a discrete event simulation framework called INET/OMNeT++. One of the modelled schemes is the Enhanced Route Optimization which is an improved version of Route Optimization while the other one is Flat Access and Mobility Architecture which implements distribution schemes in a different aspect. Finally I present the results of the executed simulations that will highlight which solution could be better suited for deployment in real-life networks in the future.
