Many mobile applications in wireless networks such as military battlefield, emergency response, mobile commerce, online gaming, and collaborative work are based on the notion of group communications. Designing security protocols for secure group communications in wireless networks faces many technical challenges due to unique characteristics of wireless networks including resource-constrained e...

Tactical mobile robots used in military and law enforcement operations normally require a robust, long range, and non-line-of-sight communications link to the remote control station. High frequency digital communications, which overcome problems encountered by tethered links and analog radios, are subject to line-ofsight (LOS) limitations. This is often impossible to maintain in urban environme...

Users of computer systems may often require the private transfer of messages/communications between parties across a network. Information warfare and the protection and dominance of information in the military context is a prime example of an application area in which the confidentiality of data needs to be maintained. The safe transportation of critical data is therefore often a vital requirem...

Based on the speech coding technology, in this paper we propose a new method encoding the speech signal by the bionic pattern recognition technique. Using this new encoding method, the text message can be received after using biomimetic pattern recognition of the speaker’s voice. And the information related to the speaker’s individual characteristics can be obtained by “comparison” between the ...

This paper describes the application of artificial intelligence techniques for design and subsequent use in monitoring and control of communications networks. We describe the development of a knowledge base which provides a model of the communications network during the network design process. We then describe utilization of this knowledge base using various artificial intelligence techniques I...

America has been in space for over 40 years, yet there seems to be little common understanding of how to integrate space into all aspects of military operations. A common vision for the military application of space forces is vital for America in a period of growing space reliance and decreasing space budgets. Our fielded forces rely on space for a variety of essential missions including commun...

The Haiti earthquake relief effort in 2010 involved numerous civil and military organizations engaged in vigorous relief operations, exemplifying rapid deployment of logistics, transport, security and medical supplies. Yet, to determine the effectiveness of these operations, and to understand how these various organizations collaborated, and eventually how to improve the future overall effectiv...

A command, control, computers, and communications interoperability assessment framework has been developed to track progress in interoperability over time. It covers technical, human, organizational, and policy/legal aspects of interoperability. Inputs to the framework include military and civilian personnel, domain experts, feedback from various nations, and past methodologies for characterizi...

Many future military operations are expected to occur in urban environments. These complex, 3D battlefields are extremely demanding and introduce many challenges to the dismounted warfighter. These include limited visibility, lack of familiarity with the environment, sniper threats, concealment of enemy forces, ineffective communications, and a general problem of locating and identifying enemy ...

Throughout this orientation of satellite operations, you have been exposed to the modern world's dependence on space systems. This dependence varies from simple commercial long distance calls to the implementation of a nation's strategic offensive and defensive forces. Furthermore, the United States Government and military forces require space systems support, such as early warning, navigation,...
