Abstract:

Free Space Optical (FSO) and directional RF communications could become a key enabling component for future tactical net-centric systems. Primary advantages of directional networks include high data rates, longer communication range, covertness, LPI/LPD, spatial frequency reuse, and agile topology optimization. A number of critical challenges, however, exist in providing assured connectivity and resiliency for tactical directional networks. In this lecture, an overview of the directional networking technologies will be provided with special focus on gaps in enabling future defense and security net-centric vision, characterization of connectivity and link fragility, and methods for dynamically optimizing topology for maximizing tactical network performance.
