Survivability modeling and analysis for a power-aware wireless ad hoc network

In this paper we propose a Markov model to describe the node behavior for a power-aware wireless ad hoc network, where two energy consumption (high and low) levels are assumed. Since the energy consumption level reflects all the states on the node behavior, we extend the existing DoS attack model in the literature by introducing energy consumption levels in each state. Based on the analytical results on the steady-state probability, we approximately evaluate the quantitative network survivability under three modeling scenarios; Poisson, binomial and negative binomial ones. In numerical examples, we derive the network survivability and investigate the impact on the energy consumption level in terms of the quantitative survivability analysis. It is shown that the network survivability strongly depends on the energy consumption level.
