The Case for an Adaptive Integration Framework for Data Aggregation/Dissemination in Service-Oriented Architectures

The migration to Service Oriented Architectures (SOA) implies many real-time applications distributed across large geographic areas with highly mobile users and sensors that require exchange of critical data among local as well as distant users across resource constrained networks. These emerging applications can be characterized as distributed collaborative adaptive systems. They are likely to rely on ad hoc wireless networks particularly in military and emergency response applications for transport of critical information and in many cases in multimedia form. Users of these systems are likely to have different needs or views of sensor data either because of organizational role or geographic location. In this distributed architecture, available resources must dynamically reconfigure themselves to respond to external factors such as changes in the environment, changes in short-term objectives, reallocation of responsibilities, and changes in information flow patterns. This paper describes a framework for dynamic resource management (DRM) and Quality of Service (QoS) in support of network aware applications and resiliency in ad hoc delay tolerant networking (DTN). The proposed framework is based on managing perflow, end-to-end provisioning of heterogeneous network resources in support of mission-driven resource management.
