System Support for Managing Invalid Bindings
2011
International Journal of UbiComp
Preserved Fulltext
Other Versions
To this end, we propose and implement our design approach to reconfiguration to manage invalid bindings. ...
To reduce the development efforts, our approach provides an application-transparent solution where the issue of the invalidity of bindings is handled by our system, Policy-Based Contextual Reconfiguration ...
The core design component of RAI which implements the support for managing invalid bindings is the virtual stub. ...
