Abstract:
The rapid growth in number of portable electronic devices with wireless networking capabilities
in recent times has thrown up many new computing problems and opportunities.
Such devices typically lack the processing power common to more familiar desktop and laptop
computers. They are also constrained by their limited power supply. Given the scenario
of an urban environment in which a large number of people using such devices constantly
move about with a need to share information, it is clear that existing network topologies are
inherently unsuited to supporting the sort of applications that they might need.
This dissertation project addresses the changing role of that most integral part of computer
systems in this new environment - the file system. A distributed file system called
Stirling is presented that takes advantage of both the ad hoc nature of the network environment
and the structure provided by the WAND (Wireless Ad-hoc Network for Dublin.)
This filesystem offers a set of features suited for ad-hoc networking. These features, such
as virtual file placement and latency minimisation, may be set and adjusted by users at a finegrained
level. It is envisaged that such a system may be put in place on a backbone network
such as the WAND in order that users and their devices can be guaranteed ?reachability? to
other devices from one end of the network to the other. Usability scenarios are presented and
analysed, and test cases documented.
