A simulation testbed for LPD networks with power control

Abstract

There is a growing interest in low probability of detection (LPD) communication networks due to increased focus on tactical networks, and due to improved processing capabilities for spread spectrum waveforms. The probability of detection by an interceptor is affected by design decisions made throughout the hardware and protocol levels of the communication system. Because of the difficulty of analytically modeling the effects and interactions of system design choices made at different levels of the system upon the probability of detection, particularly in the networking context, the authors have developed a combined simulation and analytical model of a network of mobile communicating nodes operating in the presence of jammers and hostile communication interceptors such as power radiometers. They use the model to examine the efficacy of dynamic power control in LPD networks.<>
