A new paradigm is introduced into the literature of computer science with the concept of service-oriented architectures: Applications are no longer confined with a predetermined set of services, but they can extend their capabilities by dynamically composing services or resources in an autonomous way. Under the paradigm, services are abstracted out from concrete resources, which can be accessed via uniform and public interfaces. Of many issues related to the paradigm of service orientation, I would like to provide a way to achieve dependability and adaptivity of service-oriented systems based on the variability management techniques of product line engineering. Currently, my research focuses on an architectural framework to deploy services at run time with high adaptivity.

Achieving Dependability and Adaptivity of Service-Oriented Product Lines Adopting SO in practice for real software and system development, however, has uncovered several challenging issues, such as how to identify services, how to determine configurations of services that are relevant to users’ current context, and how to maintain system integrity after configuration changes. Moreover, the service features may vary from a user’s point of view and thus will be subjects of configuration changes at runtime for each user. For example, in a smart home application scenario, participating entities such as sensors, actuators, and any type of computing devices, are mostly mobile and/or frequently switch to a hibernation mode to save energy. This implies they may join and leave the system scope at any time during execution. Nevertheless, we want to provide services continuously to users by using available resources. At the same time, it is critical to maintain the overall integrity of the system to guarantee an ‘expected’ level of dependability (e.g., vital monitoring service should be always available for an elderly user). Of many issues related to the adoption of service orientation for system development, we would like to achieve dependability and adaptivity of service-oriented systems based on the variability management techniques of product line engineering. This project involves in setting up clear goals in terms of dependability and adaptivity and in exploring variability management techniques to achieve the goals.
