CA-Fi: Ubiquitous mobile wireless networking without 802.11 overhead and restrictions

Hanno Wirtz, Torsten Zimmermann, Matteo Ceriotti, Klaus Wehrle
2014 Proceeding of IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks 2014  
We thus enable ubiquitous wireless communication, independent from 802.11 network structures in CA-Fi, a continuous, low-overhead communication channel concurrent to 802.11 associations.  ...  CA-Fi augments 802.11 with an association-less broadcast mechanism of up to 30 kB/s, preserving up to 70 % of simultaneous 802.11 throughput and enabling unrestricted and instant networking in the wireless  ...  ACKNOWLEDGEMENTS This work was funded by the DFG Cluster of Excellence on Ultra High-Speed Mobile Information and Communication (UMIC) and the DFG SFB 1053 "MAKI".  ...

A wireless application overlay for ubiquitous mobile multimedia sensing and interaction

Hanno Wirtz, Jan Rüth, Torsten Zimmermann, Matteo Ceriotti, Klaus Wehrle
2014 Proceedings of the 5th ACM Multimedia Systems Conference on - MMSys '14  
Orthogonally, we facilitate direct and ubiquitous mobile multimedia sensing and interaction in 802.11 and 802.15.4 within the unrestricted physical context of mobile devices.  ...  Removing the need for Internet services or wireless networks, we derive a wireless service overlay over the sensed media in the locality of a device that exposes media to applications.  ...  Acknowledgements This work was funded by the DFG Cluster of Excellence on Ultra High-Speed Mobile Information and Communication (UMIC). We are grateful to our colleague (cf.  ...
