Abstract
The protocols in the TCP/IP protocol suite used for Internet
communication do not support mobile end systems by
themselves. Encouraged by the growth of the Internet and by
technological advance in the fields of wireless
communications as well as mobile computing, a whole series
of new protocols has been proposed in the recent years in
order to provide mobility support for IP networks.
This thesis gives an introduction into two protocols for IP
mobility support that use different basic approaches. For
each protocol an implementation has been installed in the
IND network laboratory: the implementation of the Mobile IP
protocol from Stanford University and the Cellular IP
implementation from Columbia University. Special
measurement software was used to investigate performance of
these protocols, particularly with regard to packet loss
caused by handovers between two Internet access points.
