Abstract: This paper addresses the use of a mathematical network model to evaluate the reliability of capacitated mobile ad hoc network through Monte Carlo simulation which considers the following: nodes following a known failure distribution and moving according to random waypoint mobility model links with specific load carrying capacity and its existence modelled using log-normal shadowing propagation model. Given the demand, we evaluate the network reliability that the calculated channel capacity of the network is not less than the demand, considering various variants viz., propagation models and environmental conditions. The purpose of this paper is to provide such performance index for a mobile ad hoc network investigated under different scenario metrics (transmission range, coverage area and network size). Our model evaluation is supported with an example and imperative results of the network operating with different pathloss exponents are also shown.
