Abstract: In this paper a new mobility management is introduced. The main idea
in this approach is that the mobil node should manage the mobility for itself
not the network. The network nodes
provide only basic services for mobile entities: connectivity and
administration. We construct a framework called the Client-based Mobility Frame
System (CMFS) for this mobility environment. We developed the CMFS protocol as
a solution over IPv4 and we show how to use Mobile IPv6 to realize our concept.
We propose some basic mobility management solutions that can be implemented
into the mobile clients and give details about a working simulation of a
complete Mobility Management System. Example mobility management approaches
such as the centralized- and hierarchical- or cellular-like ones are also
defined and hints are given what kind of algorithms might be implemented upon
the Client-based Mobility Frame System over IPv4 and IPv6 as well. We introduce some
example algorithms that can work with the CMFS making mobility management
efficient by minimizing signalling load on the network. In the present work
modeling and detailed discussion on the parameters of the algorithms is given
and comparison to existing mobility approaches and protocols is done. We
prepared a simulation to test our protocol and to back up the proposals we
provide the reader with simulation results. We stress that still one the most
important benefit of our findings is that all the MNs can run different
management strategies and can optimize mobility for themselves.
