Networks and Communications, Computing and Cyber

Research concentrates on understanding and exploiting information’s interactions with socio-technical networks, particularly communications, and command and control networks, both formal and social. The objective is to develop novel techniques to connect, protect and process information at the tactical edge to enable Soldiers to operate in a contested and congested operational environment. Of particular importance is Network Science – the study of structure, dynamics, behaviors and evolutions of networks, especially in the context of interactions between communications, information and social networks. Research to protect these networks concentrates on understanding and exploiting interactions of information with cyber attackers – human and/or intelligent agents. These interactions involve friendly operations against adversary information systems and networks, defense of friendly information systems and networks, and assurance of persistent information support to Soldiers even when parts of the friendly systems and networks are compromised. Key to operating at the tactical edge are techniques to compute and fuse information that may be distributed across the edge network to provide Soldiers with relevant information needed to dominate and win.

C4I in Complex Environments

Quality of Information (QoI) for Semantically-Adaptive Networks (ALC)
Develop a foundational science to model, characterize, and control information delivered through multi-genre networks based on the semantics and context of information requests. With growing volume of information available in tactical and strategic networks, network operators and commanders will require enhanced capabilities to filter and process information. This includes development of 1) semantically aware communication and compression techniques from an information theoretic perspective, 2) protocols to provide efficient, quality-aware semantic information delivery to analysts and decision makers, 3) network design approaches to maximize QoI metrics dynamically, either centralized or decentralized, and 4) QoI and semantic-aware resource allocation and management algorithms that achieve the trade-offs between resource usage and quality delivered.

Supporting Facility:
Network Science Research Laboratory (ALC)
Facility that provides a controlled, repeatable emulation environment for the research, development, and evaluation of network science and information assurance algorithms for tactical wireless mobile ad hoc networks.

Geometric & Topological Structures in Composite Networks (ALC)
Adapt advanced mathematical theory from geometry and topology to network science via an empirical study of real network data. Since many networks of interest do not reside in an existing (known) geometric space and instead form their own intrinsic geometric and topological space, many geometric and topological concepts have relevance to structural characterizations of networks (e.g., power-law relationships and robustness) and processes on networks (e.g., link prediction, community detection, and epidemic spreading).
