The mobile computing paradigm is becoming a reality due to the advent of mobile devices such as, PDA and Smart Phones having wireless interface to WWW. As a result, the high-end applications related to mobile multimedia and distributed digital contents have gained much attention. However, the existing distributed and mobile file systems are not adequately suitable to support such applications handling the challenges offered by mobile computing systems. In this paper, the concept, design architecture and consistency model of Virtual memory based Mobile Distributed File System (VMDFS) are proposed based on thin-mobileclient/ fat-server model. VMDFS creates the migrate-able virtual memory based mobile file system on top of the disk file systems of remote servers employing dynamic frame-lock to reduce network latency and to attain high-performance. An abstract mathematical model of VMDFS is constructed and associated properties are evaluated. The kernel-level implementation framework of VMDFS is illustrated based on Linux 2.4.22. The network paging latencies for LAN, Wireless VPN and 2.5G GPRS are measured experimentally. The results indicate that VMDFS is realizable.
