System Support for Managing Invalid Bindings

Lachhman Das Dhomeja, Yasir Arfat Malkani, Azhar Ali Shah, Khalil Khoumbati
2011 International Journal of UbiComp  
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.  ...

Javanaise: distributed shared objects for Internet cooperative applications [chapter]

D. Hagimont, D. Louvegnies
1998 Middleware'98  
Our system support relies on object replication on the client nodes. Logically related objects are grouped in clusters, the cluster being the unit of sharing, replication and coherence.  ...  We have implemented a service for the development of distrib uted cooperative applications on the Internet.  ...  able to invalidate and update clusters for consistency management.  ...

Dependency Management in Smart Homes [chapter]

Daniel Retkowitz, Sven Kulle
2009 Lecture Notes in Computer Science  
In this paper we describe how we extended our existing dependency management approach for smart home services with a mechanism for monitoring service bindings and handling access control based on priority  ...  Thus there is need for easy to manage tool support and an intuitive mechanism of interaction with the eHome.  ...  Summary and Outlook In this paper we described our approach to support dependency management for eHome systems dealing specifically with the resource constraints arising in ubiquitous computing scenarios  ...

Describing Dynamism in Service Dependencies: Industrial Experience and Feedbacks

Clement Escoffier, Pierre Bourret, Philippe Lalanda
2013 2013 IEEE International Conference on Services Computing  
To make it easier for the development team, we have used and extended the iPOJO service component model.  ...  Indeed, dynamism is a complex concern, difficult to perceive and manage by developers.  ...  Invalidation is used for component offering services that cannot be satisfied if the service dependencies are not fulfilled.  ...
