Paper Abstract:
|
In this paper the Coda distributed file system is presented as a tool to manage mobile computing systems in terms of the
availability of data. The Coda file system introduces a number of features such as ability to function either in the
disconnected or connected state as well as pre-fetching of data, caching of data and replication of data. It can thus assist
disconnected systems operating in isolation from their network servers temporarily by caching some files to a local
directory. This achieves some server relieve as clients demand data continuously. It is projected that the properties of the
Coda file system can be exploited to reduce congestion in mobile computing.
By implementing the Coda file system in a mobile network, it is projected that servers can be temporarily relieved of
some mobile nodes, and thereby achieving reduction in the data demand on the server. This will produce a reduction in
network traffic in terms of delay, packet loss and throughput, and assist to improve network performance. We propose a
design as well as simulation results of effectively utilizing the Coda file system to improve network performance in
mobile computing systems. |
