Experience with Disconnected Operation in a Mobile Computing Environment
[chapter]
The Kluwer International Series in Engineering and Computer Science
Preserved Fulltext
In this paper we present qualitative and quantitative data on file access in a mobile computing environment. ...
This information is based on actual usage experience with the Coda File System over a period of about two years. Our experience confirms the viability and effectiveness of disconnected operation. ...
Qualitative Evaluation The nature of our testbed environment has meant that we have more experience with voluntary than with involuntary disconnected operation. ...
