The tactical edge network emulation tool (TENET) hardware integration system (THIS) is designed to characterize higher layer responses to the dynamic physical layer topology of a tactical network utilizing directional communication links. THIS emulates the mobile, tactical, network environment using the hardware in a static infrastructure. MATLAB-based tools implement the TENET emulation to simulate...
Dynamic topology control schemes have been discussed earlier for continuously optimizing tactical mesh topologies to maximize the network connectivity. A dynamic optimization of the physical layer topology, however, is treated by layers-1 and 2 as a disruption and usually triggers re-computation of end-to-end paths. Higher layer routing algorithms may not always determine the same path as intended...
Free-space optical communication (FSOC) systems will be an important part of future networking infrastructures. With the growth in demand from users - both commercial and military - and the scarcity of available RF spectrum, FSOC has the potential to offer a solution. FSOC capacity can easily reach 10psilas Gbps or more over useful ranges. However, the ability to construct an FSOC network has many...
Very high-speed data links from fast-moving mobile terminals to satellites are attractive in many military applications. In order to provide such high-speed data rates we consider a multiple-input multiple-output (MIMO) free space optical (FSO) system for the earth-to-satellite link. In this case the signal is transmitted via closely-spaced multiple transmit apertures and the receiver consists of...
A transparent four-fiber optical channel shared protection ring with span and ring switching is demonstrated experimentally. For a typical regional long haul ring network with 8 nodes and 1200-km circumference, up to 80 wavelengths can be protected in less than 50 ms.
