Large-scale systems of systems integration projects we are, or have been involved in include BioNet, RESCUE, RUNES, ORION/Conceptual Architecture and CAMERA.

In these projects, the relevant requirements categories range from well-known and comprehensively researched data-/application-/process-integration to so far much less understood integration of heterogeneous policy, governance, trust, security and privacy zones.

We have encountered examples of such integration challenges within a wide range of projects conducted at Calit2, with dozens to hundreds of stakeholders involved. Examples include the BioNet and RESCUE/Responsesphere projects. BioNet was a DHS/DTRA sponsored project, seeking to coordinate military and civilian capabilities to detect, characterize and manage the consequences of a biological attack. This involved, among others, establishing joint concepts of operations (business processes), as well as a software and systems integration architecture supporting these processes. A key goal was to provide common situational awareness to ensure timely, effective, and consistent response. Similarly, the NSF-funded RESCUE/Responsesphere project seeks to "radically transform the ability of responding organizations to gather, manage, use, and disseminate information within emergency response networks and to the general public. Depending upon the severity of the crisis, response may involve numerous organizations including multiple layers of government, public authorities, commercial entities, volunteer organizations, media organizations, and the public".

In the project RUNES, we work on architecture designs for a standardized, reconfigurable service-oriented middleware for a large scale systems of embedded systems integration project. The goal here is to expand and simplify existing and future networks of devices and embedded systems. For the ORION program we were involved in designing a conceptual architecture for future virtual ocean observatory cyber infrastructure. This conceptual architecture is built entirely from service-oriented principles to integrate vastly heterogeneous instrument networks, computational capabilities, data management, as well as scientific processes together with the corresponding management and presentation capabilities. In the CAMERA project, we apply service-oriented ideas to an integrated system of sensor networks and genomics laboratory workbenches for the research of marine life. We contribute to creating a cyberinfrastructure for microbiological and genetic analysis of marine life forms.

For our research into all aspects of service-orientation we also collaborate with automotive companies such as Ford Motor Company and Toyota ITC. We have thoroughly investigated automotive service notions, corresponding development processes and description techniques. We have created a suite of tools supporting service-oriented development in automotive projects, as well as a vehicular testbed for service-based real-time automotive components, applicable in conformance and performance testing. We are now extensively researching failure modeling and failure management in the automotive domain.
