Disconnection-Resilient File
system for Mobile Clients
Abstract: With
the advancement of wireless networks and mobile computing, there is an
increasing need to build a mobile file system that can access data efficiently
and correctly anywhere and at anytime.
We
propose a novel mobile distributed file system design, which provides high
available and reliable storage for files and guarantees that file operations
are executed in spite of concurrency and failures. The design is intended to
fit mobile clients (e.g. PDAs and cell phones) that
have limited storage space and cannot store all data they need, yet they
require to access these data at all times. We adopt a server-side caching in
order to guarantee sufficient caching space to all mobile clients, and ensure
the availability of files in case of
clients' failures.
