Reliability Evaluation for the C4ISR Communication System via Propagation Model

The effect of path loss on the reliability of wireless communication in Military C4ISR (Command, Control, Communication, computer, Intelligence, Surveillance and Reconnaissance) Architectures has drawn much attention. Previous work were focused on the reliability assessment of infrastructure, but its link reliability has not been fully considered. This paper puts forward a new method for the reliability assessment of the C4ISR communication through the analysis of the traditional suburban Millimeter Waves (MMW) path loss models. To evaluate the effects of the path loss on the link reliability, we used the lognormal distribution to fit the random distribution curve of the communication distance. Derived by formula, the PDF (Probability Distribution Function) and the CDF (Cumulative Distribution Function) of the path loss value on different communication distance have been obtained. Finally, the C4ISR communication reliability at different frequencies are calculated based on the threshold of the path loss value. The advantage of this method is that it can reflect the effects of the environmental factors and carrier frequency on the reliability of the C4ISR wireless communication.
