Enabling information management systems in tactical network environments
Proceedings of SPIE(2009)
摘要
Net-Centric Information Management (IM) and sharing in tactical environments promises to revolutionize forward
command and control capabilities by providing ubiquitous shared situational awareness to the warfighter. This vision
can be realized by leveraging the tactical and Mobile Ad hoc Networks (MANET) which provide the underlying communications
infrastructure, but, significant technical challenges remain. Enabling information management in these highly
dynamic environments will require multiple support services and protocols which are affected by, and highly dependent
on, the underlying capabilities and dynamics of the tactical network infrastructure.
In this paper we investigate, discuss, and evaluate the effects of realistic tactical and mobile communications network
environments on mission-critical information management systems. We motivate our discussion by introducing the Advanced
Information Management System (AIMS) which is targeted for deployment in tactical sensor systems. We
present some operational requirements for AIMS and highlight how critical IM support services such as discovery,
transport, federation, and Quality of Service (QoS) management are necessary to meet these requirements.
Our goal is to provide a qualitative analysis of the impact of underlying assumptions of availability and performance of
some of the critical services supporting tactical information management. We will also propose and describe a number
of technologies and capabilities that have been developed to address these challenges, providing alternative approaches
for transport, service discovery, and federation services for tactical networks.
