Reducing Traffic of Messages in Distributed Editing Systems

With the embedded mobile devices greatly proliferating, the communications under ubiquitous environment are welcomed in terms of collaborative work. For the limited bandwidth of wireless network and the limited size of screen on palmtop computer, tailored communication and data exchanges between desktop and mobile sites was studied in our research. We proposed a grouping scheme together with Sending on Demand Policy to reduce traffic of messages in distributed collaborative editing systems implemented by various types of devices. Consistency maintenance relevant to grouping was studied out with a Linked History Buffer The scheme had been implemented in our prototype system that can work well in heterogeneous environments.
