Description of IPv6 network mobility demonstrators

The purpose of the mobility demonstrator was to determine how well Mobile IPv6 and the basic network mobility (NEMO) protocol perform when utilised in environments that are highly mobile. In cooperation with the Cockermouth mountain rescue team, the University of Lancaster have examined the feasibility of using mobile routers to provide them with an on-mountain data networking solution.

Integrating mobile router technology into the existing mountain rescue operational procedures is very challenging. Not only is there the problem of providing optimum connectivity in remote mountainous regions, but there is also the need to cater for several communicating entities within a command hierarchy. Even a simple search will consist of several volunteers of a single rescue team spread across a wide area. The volunteers need to communicate with each other and their mobile response vehicle, which in turn needs to communicate with its home base and other entities such as ambulance services and the RAF (Royal Air Force). For large searches the situation is more complex as there may be several rescue teams trying to work in a co-ordinated fashion.

The demonstrator replicates both network and mobile node roaming within nested mobile networks. Furthermore, an application was developed to illustrate the constantly changing network topological information to the user. Apart from the mobile protocols, problems were discovered with the currently available wireless interface technologies and battery technologies.
