Dynamic planning and weaving of dependability concerns for self-adaptive ubiquitous services

Romain Rouvoy, Frank Eliassen, Mikaël Beauvois
2009 Proceedings of the 2009 ACM symposium on Applied Computing - SAC '09  
Thus, to reduce this effort, we propose to integrate the Aspect-Oriented Programming (AOP) principles into the MUSIC planning-based adaptation middleware in order to dynamically plan and weave dependability  ...  However, the integration and the configuration of these mechanisms depends not only on the type of service accessed, but also on the surrounding environment.  ...  Therefore, applications are only suspended if a reconfiguration needs to be operated. Then, the context plugins triggering the reasoning process are based on Fuzzy Logic [28] .  ...
