Adaptive groupware for wireless networks

T. Whalen, J.P. Black
1999 Proceedings WMCSA'99. Second IEEE Workshop on Mobile Computing Systems and Applications  
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.  ...

The support of mobile-awareness in collaborative groupware

Keith Cheverst, Gordon Blair, Nigel Davies, Adrian Friday
1999 Personal Technologies  
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.  ...

Adaptive forward error correction for real-time groupware

Jeff Dyck, Carl Gutwin, Dwight Makaroff
2012 Proceedings of the 17th ACM international conference on Supporting group work - GROUP '12  
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] .  ...

Communication and coordination patterns to support mobile collaboration

Roc Messeguer, Sergio F. Ocho, Jose A. Pino, Leandro Navarro, Andres Neyem
2008 2008 12th International Conference on Computer Supported Cooperative Work in Design  
Ad-hoc networks are not supported by infrastructure. The nodes in the network use wireless communication and a dynamic topology for data dissemination and gathering.  ...  The current wireless communication norms supporting mobility have a limited communication threshold. For example, the Wi-Fi threshold is about 200 meters in open areas and 20 meters in built areas.  ...  The work of Andrés Neyem was partially supported by the Scholarship for Thesis Completion from CONICYT (Chile).  ...

However, by simply plugging both proxylets into the proxy, they cooperate in a synergistic manner to correct additional types of burst errors occurring on the wireless network.  ...  When multimedia applications such as Pavilion are executed in a wireless environment, proxies are often used to represent mobile hosts to the rest of the network [8], [11] [16], [17], [18], [19].  ...

Games have similar demands and characteristics to groupware, but unlike the applications studied by academics, games have provided production-quality real-time interaction for many years.  ...  Networked games can provide groupware developers with important lessons in how to deal with real-world networking issues such as latency, limited bandwidth and packet loss.  ...  Adaptive window sizes for groupware.
