Challenges of ULS systems
Fundamental gaps in our current understanding of software and software development at the scale of ULS systems present profound impediments to the technically and economically effective achievement of information superiority. These gaps are strategic, not tactical. They are unlikely to be addressed adequately by incremental research within established categories. Rather, we require a broad new conception of both the nature of such systems and new ideas for how to develop them. We will need to look at them differently, not just as systems or systems of systems, but as socio-technical ecosystems. We will face fundamental challenges in the design and evolution, orchestration and control, and monitoring and assessment of ULS systems. These challenges require breakthrough research.
The ULS System Research Agenda presented in Ultra-Large-Scale Systems: The Software Challenge of the Future provided the starting point for the path ahead. The study proposed a ULS systems research agenda for an interdisciplinary portfolio of research in at least the following areas:
- Human Interaction
- Computational Emergence
- Computational Engineering
- Adaptive System Infrastructure
- Adaptable and Predictable System Quality
- Policy, Acquisition, and Management
Socio-adaptive systems focus on the effects of the human element in a system.
Specifically, socio-adaptive systems refer to large-scale systems comprising
distributed system resources such as processors and wireless networks. Humans
rely on these resources to carry out missions. Continuous change in the network
coupled with changing needs of missions supported by the system pose
challenges. Additionally, appropriate responses to changing needs rely on the
expressed needs of humans. Therefore, factors such as human self-interest must
be accounted for in system design.
Our research in socio-adaptive systems involves
- developing new resource-allocation techniques for
mobile ad hoc networks
- applying market mechanisms to ensure efficient resource
reallocation in continuously changing tactical settings
