Two of the major concerns in tactical military wireless communication networks are covertness and throughput. Impulse Radio is an u!tra-wideband code division muhi-ple access (U WB-CDMA) technique being considered as the physical layer for future networks. Impulse radio exhibits low power spectral density and relatively high immunity to fading but suffers(More)
The tack of a low probability of detection (LPD) wave-form is often cited as one of the criteria against the use of Commercial Off-The-Shelf (COTS) communications systems in the tactical military environment. However, there is rarely any quantitative evidence given to support this understandable qualitative assertion. We propose a method for quantitatively(More)
An expanded and improved information technology capability is the fundamental heart of the network-centric warfare (NCW) vision. The NCW vision is worthy and is a direct path to achieving improved collaborative power and information dominance. The potential benefits of diverse information sharing and interconnection are manifold, but at the same time(More)
Future military communications systems are expected to exchange information in a seamless and reliable manner across heterogeneous networks composed of both jixed, wired nodes and mobile, wireless nodes. While commercial protocols such as TCP/IP have improved ihe seamiessness of military communications systems, the use of TCP/IP in the mobile, wireless(More)
