Designing an NFS-based mobile distributed file system for ephemeral sharing in proximity networks

This paper addresses the need Cor ephemeral file sharing in proximity networks and explores the necessary requirements that a mobile distributed file system (M-DFS) should satisfy in order to operate properly under typical conditions of such networks.. We chose an M-DFS design based on the widely deployed NFS because of its ease of portability, lightweight model and its use in the past as a basis for building distributed file systems. To identify NFS shortcomings in proximity networks using B luetooth and 802.11, we measured its performance under various bandwidth and delay combinations, network disconnections, low signal reception zones and in the presence of packet loss. Based on our observations, we present some proposals for the design of an M-DFS suitable for ephemeral sharing and describe a possible prototype implementation using an NFS loopback server approach.
