mated and adaptive deployment of communication services for QoS. The application domain targets cooperative group activities applied to military emergency operation management systems. Various models are introduced to represent the tion decision process relies on structural model transformations while its enforcement is based on the dynamic composition of micro-protocols and software components. Automated deployment is performed both at the transport (i.e. UDP-TCP level) and middleware level. The architecture to support automated network management based on these models is introduced and illustrated.
IntroductionCooperative group activities using wireless mobile communicating systems constitute an increasingly evolving application domain. It is likely to be one of the most important directions that may enable reliable and efficient human and machine-tomachine cooperation under the current networking systems and software, and may deeply shape their future deployment. Such activity-support systems have to deal with dynamically evolving activity-level requirements under constantly changing network-level unpredictable constraints. Maintaining reliable connectivity and QoS in such a communication context is difficult. Adaptive service provisioning should help the different provisioning actors to achieve this goal and constitutes a challenge for different research communities.Ad hoc solutions are not likely to be applicable to solve such a complex problem. Providing a basic framework for automated services and QoS deployment may constitute an important contribution towards solving such a problem.
The design of wireless cooperative mobile service-oriented applications with machine-to-machine communication capabilities requires providing solutions that include service and Quality of Service (QoS) provisioning as key features. Self-adaptability and self-organization are properties that help managing services and associated QoS for communication, vertically and horizontally. This paper addresses self-adaptability as a key feature for modeloriented and architecture-driven QoS management. We study the different abstraction levels at which the adaptability can be managed. Such decomposition allows mastering the complex handling of self-adaptive group-wide QoS for cooperative activities supported by wireless and mobile ad-hoc communications. A case study based on cooperative groupactivity support is developed to illustrate the proposed concepts.
