Abstract
Mobile systems such as handheld PC's are becoming commodity items but
are sold with relatively simplistic mobility support software. It is
advantageous to consider a interoperable middleware solution to this
support need which is independent of any particular operating system.
Our DISCWorld middleware environment was originally designed as a grid
enabling system on fixed networks, but due to its compact footprint
and implementation in Java, it lends itself well to the support of
mobile devices on a wireless network. We describe how our system
addresses mobile wireless issues and the problems of: disconnection
and temporary nomadic operations; variability and volatility of
bandwidth; user transparency; asynchronous communications and data
replication management. We are investigating WaveLAN and Bluetooth
wireless interoperability with our system. We discuss the general
problem of where mobility support management features should appear in
a general software stack model.
