Chapter 1
Introduction
There have been many changes in the face of computing in the past decade, one of which is
undoubtably the introduction of mobile computing. Over the past few years, mobile computing
has become widely accepted by the general public as a useful productivity tool, with wireless
hotspots becoming more and more common.
The ability to travel whilst accessing the Internet, provides the opportunity to increase productivity
by making use of previously unusable time, and makes Internet access easier and more
flexible. It may soon be possible to access the Internet from public transport, and aircraft. Some
pilot studies have already been done to test the feasibility of this hypothesis, and so far have
been very successful. Boeing recently trialed a broadband Internet connection in its aircraft in
conjunction with the German Airline Lufthansa, who is now planning to use the system in most
of their fleet as a way to differentiate their product from other airlines [1].
Whilst these trials are a great step forward, diligent studies have shown that the present Internet
architecture is not suitable for this sort of mobility, with groups of users (or networks), moving
together. This is referred to as Network Mobility, where a network itself is mobile as opposed to
an individual host. Protocols currently used for mobility such as Mobile IPv4 and Mobile IPv6,
do not provide any way to exploit the fact that all of the passengers on the plane are moving
together. As such, their performance is far below optimal [7], and involves significant overhead
due to the fact that each host is performing handoffs, sending binding updates, and tunneling
packets back to their home agent.
