In the recent past, advances in hardware technologies, such as portable
computers and wireless communication networks have engendered a new paradigm of
computing, called mobile computing. Users carrying their portable (palmtop,
laptop) computers equipped with wireless communication devices are capable of
accessing shared infrastructure independent of their physical location. They
want to gain access to the global information systems while they are roaming
around, do their work while they are away from their offices. Such a new
environment introduces new technical challenges in the area of information
access. Traditional techniques for information access are based on the
assumptions that the location of hosts in distributed systems do not change and
the connection among hosts also does not change during the computation. In a
mobile environment, however, these assumptions are rarely valid or appropriate.
Researchers in the field of mobile computing focused on networking,
operating systems, information management systems and traditional distributed
database systems. They have revised the old applications to port them to the new
environment. Research in networking and communications include new addressing
and routing schemas, support for efficient multicasting and broadcasting, data
compression and relocation transparency. Research in operating system addresses
security issues, file systems that support disconnected operation and caching
techniques. Research in information management system addresses resource
management, information acquisition and data distribution. Finally, research in
traditional distributed database system focus on replica management, concurrency
control and transaction processing.
Mobile information access involves retrieving information from wired
service providers. It is inefficient and some times impossible for a resource
poor mobile device connected over a low bandwidth wireless link to coordinate
such activity. This requires the data from shared file systems, relational
databases, object-oriented databases, and other repositories be accessible to
programs running on mobile hosts. Disconnected operation, a concept first
conceived and demonstrated in Coda, is an important initial step in mobile
computing. In this mode of operation, a client continues to have read and write
access to data in its cache during temporary network outages. Transparency is
preserved from the viewpoint of applications because the system bears the
responsibilities of propagating modifications and detecting update conflicts
when connectivity is restored. The ability to operate disconnected can be useful
even when connectivity is available.
The objectives of the highly selective, interactive workshop are to be a
source for mobile information systems research and development, and to serve as
an outlet for facilitating communication and networking among mobile information
systems researchers, practitioners, and professionals across academics,
government, industry and students. It is aimed to provide a forum for
state-of-the-art development and research, as well as current innovative
activities in mobile information systems. The main goal will be to provide
timely dissemination of information. WMIS workshop format makes it ideal for
presenting and discussing new directions or controversial approaches in mobile
information systems like distributed data management in mobile computing and
design of distributed file systems for mobile users.
We solicit submissions of position papers that focus primarily on
applications and systems and that propose new directions of research, advocate
non-traditional approaches to old (or new) ideas, or generate controversy and
discussion. The Workshop provides a general platform for academicians,
researchers, students, engineers and industries to present their unpublished
research findings in any field of Mobile Computing and Systems, and other
related areas.
