Object Sharing Over Mobile Devices

With the advent of hand-held computing devices, the need for collaborative applications has become more urgent. In order to allow for the design of collabo-rative applications, a common infrastructure for the sharing of data is required for mobile devices. Such an infrastructure should be built for devices that have low compute capabilities and have low bandwidth, high latency network connections. The infrastructure should also allow for such devices to periodically disconnect from the network and reconnect, as is typical of the use of hand-held computing devices. Typical software implementations of distributed shared memory are not suitable for mobile devices. Thus this study implements and explores a software based shared object system for mobile devices. An application was built on top of this infrastructure. The design, implementation, results and limitations of the whole system are described.
