Radio network modeling using criticality and conditional probability theory

Criticality, as defined by K.K. Aggarwal (Proc. Ann. Reliability and Maintainability Symp., p.86-9, 1989), is shown to be an adaptation of conditional probability theory. Both of these methods are shown to be acceptable techniques for modeling a simple radio network. However, the equivalent parallel-configuration approach provided a much simpler way of modeling the radio network problem, by using standard techniques in a new way. The logical interpretation of not-fully-critical subunits is clearly modeled with a simple manipulation of the standard reliability block diagram. The equivalent parallel-configuration approach is shown to be useful in modeling any situation where failed components may or may not lead to system failure
