  This paper presents a games-in-games approach to provide design guidelines
for mosaic command and control that enables the secure and resilient
multi-domain operations. Under the mosaic design, pieces or agents in the
network are equipped with flexible interoperability and the capability of
self-adaptability, self-healing, and resiliency so that they can reconfigure
their responses to achieve the global mission in spite of failures of nodes and
links in the adversarial environment. The proposed games-in-games approach
provides a system-of-systems science for mosaic distributed design of
large-scale systems. Specifically, the framework integrates three layers of
design for each agent including strategic layer, tactical layer, and mission
layer. Each layer in the established model corresponds to a game of a different
scale that enables the integration of threat models and achieve self-mitigation
and resilience capabilities. The solution concept of the developed multi-layer
multi-scale mosaic design is characterized by Gestalt Nash equilibrium (GNE)
which considers the interactions between agents across different layers. The
developed approach is applicable to modern battlefield networks which are
composed of heterogeneous assets that access highly diverse and dynamic
information sources over multiple domains. By leveraging mosaic design
principles, we can achieve the desired operational goals of deployed networks
in a case study and ensure connectivity among entities for the exchange of
information to accomplish the mission.
