The future digital battlespace will be a fast-paced and frenetic environment that stresses information communication technology systems to the limit. The challenges are most acute in the tactical and operational domains where bandwidth is severely limited, security of information is paramount, the network is under physical and cyber attack and administrative support is minimal. Hyperion is a cluster of research projects designed to provide an automated and adaptive information management capability embedded in defence networks. The overall system architecture is designed to improve the situational awareness of field commanders by providing the ability to fuse and compose information services in real time. The key technologies adopted to enable this include: autonomous software agents, self-organizing middleware, a smart data filtering system and a 3-D battlespace simulation environment. This paper reviews some of the specific techniques under development within the Hyperion sub-projects and the results achieved to date.
