Adaptive groupware for wireless networks
1999
Proceedings WMCSA'99. Second IEEE Workshop on Mobile Computing Systems and Applications
Preserved Fulltext
Current groupware systems do not work well over wireless networks, as a wireless connection is of variable and often poor quality. ...
Our experiments with a multi-user text editor revealed several strategies for adaptive groupware. Applying these strategies demonstrated a bandwidth reduction in one scenario of over 90%. ...
Acknowledgments Tara Whalen would like to thank Mike Nidd for technical support of this research and Mark Roseman for many helpful comments on this paper. ...

Computer supported collaboration systems, or groupware, are being used more and more in the real life. ...
This is because the system has no way to adapt itself to the dynamic changes in the bandwidth, a well-known attribute for wireless environments. ...

Abstract= This paper explores the need for mobile-awareness in groupware designed for use in a mobile environment. ...
The motivation for providing this additional form of awareness is that current groupware tends to assume a reliable and constant quality of communications that does not exist in a mobile environment. ...
For example, mobile computers can be either disconnected, weakly connected by low-speed wireless networks such as GSM, or fully connected by highspeed networks ranging from Ethemet to ATM. ...

To address this problem, we investigated the use of an application-level networking technique called adaptive forward error correction (AFEC) for real-time groupware. ...
Our study shows that groupware AFEC can be a useful tool for improving the realworld performance and usability of real-time groupware. ...
Losses on wireless networks (cellular networks and wireless LANs) can be much higher, up to and even higher than 20% on average for long-distance WiFi networks [20] . ...
