Operationally realistic testing of network centric tactical applications in a lab environment

Lab-based operationally realistic testing for the next generation tactical SA, C2 and network management applications over wireless tactical network architectures has always been a challenge due to limited access to live radio hardware and the inability to set up the operational environment in the lab even if live assets are available. In this paper we describe how network emulation can be the basis for a lab-based testbed that offers an operationally realistic environment to test live tactical applications. Our approach involves the use of high fidelity models to represent the underlying tactical network as well as the tactical environment to a high degree of accuracy such that the live applications cannot discern between live and emulation. Such an approach can in a cost effective manner address the challenges of development test and evaluation that several DoD programs are currently facing, as well as be employed in lab based risk reduction activities that are conducted prior to live operational test events (such as the NIEs). We illustrate our approach with a case study on how network emulation can be used for operationally realistic testing of the JTRS Enterprise Network Manager application in a lab based environment for both development testing as well as lab-based risk reduction prior to a live operational test.
