Improving Awareness in Mobile CSCW

C. Papadopoulos
2006 IEEE Transactions on Mobile Computing  
Following through this development, we investigate opportunities for improving awareness in mobile environments, with a view to enable collaboration under power constraints and transitory network disconnections  ...  To avoid user disruption, this protocol notifies awareness information in a multicast fashion, while the bandwidth is allocated dynamically among notifications and data requests, minimizing thus the time  ...  Later, RoamWare [39] enabled mobile meetings via chat and e-mail messages and managed also to minimize user disruption.  ...

Low-Overhead Handover-Skipping Technique for 5G Networks

Cristo Suarez-Rodriguez, Ying He, Beeshanga A. Jayawickrama, Eryk Dutkiewicz
2019 2019 IEEE Wireless Communications and Networking Conference (WCNC)  
Moreover, we have benchmarked several state-of-the-art handover schemes for 5G networks against ours in a realistic urban environment with user mobility trace data.  ...  Mobility in multi-tier dense cellular networks calls for a change in the way it has been traditionally handled in an always-on world, where users take universal data access for granted.  ...  The S1 interface is a star network that links the advanced gateway with each cell and carries the sum of all user data, whereas the X2 interface is a mesh network that enables signalling exchange among  ...

UbiData

Abdelsalam Helal, Joachim Hammer
2004 SIGMOD record  
Mobile users today demand ubiquitous access to their data from any mobile device and under variable connection quality.  ...  We refer to this requirement as any-time, any-where data access whose realization requires much more support for asynchronous and disconnected operation than is currently available from existing research  ...  Device-independent data access, which allows users to switch among different mobile devices of different capabilities without the capability to access the data. 3.  ...
