Mobile devices, such as smart phones, tablets, and netbooks, are now becoming increasingly popular. Effective access to remote files on servers in the network should be granted to the user. Today's common distributed file systems, such as OpenAFS, Coda, and others, are not suitable for use on mobile devices. The user is forced either to access a particular server or at least to write to a server containing a master write replica. The path to the data is not chosen by the file system. So, the data transmission cannot reflect the user's actual position. The authors propose a new file system supporting a multi-master write replica and routing the data requests.
