    abstract = {This thesis presents some extensions to Mobile IP designed to
better adapt this protocol to wireless networks. Specifically, the
foreign-agent selection process is studied in depth and several selection
criteria are proposed and implemented as extensions to an existing Mobile IP
software package. \par Wireless computer networks bring many advantages to
those environments where network connectivity is required subject to
constraints such as flexibility, affordability, and scalability. Wireless
Local Area Networks (LANs) can be quickly installed in cases where
traditional networks are not a feasible option for reasons like deployment
time, cost, etc. Mobile IP is a protocol that provides support for roaming of
computers between different networks. Each Mobile IP-enabled computer (mobile
node) has a fixed home agent on its original network that keeps track of the
mobile node's location at all times. The protocol specifies several different
mechanisms for the mobile node to keep its home agent updated about its
location every time it moves to another network. One of those mechanisms
requires the mobile node to select a temporary gateway computer (foreign
agent) at the visited network; this computer will serve as the mobile node's
default router to the rest of the network and will forward location updates
to the mobile node's home agent. In a wireless networking environment, mobile
nodes will likely encounter situations in which there are several candidates
from which to select a foreign agent. However, the Mobile IP protocol does
not specify policies to use in such cases. The extensions developed in this
thesis approach this problem. Performance measurements of Mobile IP-enabled
wireless LANs using these extensions are also presented and analyzed. In
terms of throughput for TCP bulk data transfer, compared to the throughput
achieved from using the original Mobile IP implementation, these Mobile IP
extensions led to a performance improvement of up to 20\% under certain
scenarios.}
