Research on quantitative analysis model of MANET survivability

Mobile Ad hoc network (MANET) is a multi-hops wireless network without fixed infrastructure. Now how to evaluate network survivability performance is the key work of the research of MNAET. According to the requirement of the survivability of MANET, a more comprehensive hierarchical model for quantitative evaluation of survivability is proposed. The model was constructed based on continuous time Markov chain and M/Ml/K queue theory, which could analysis the steady-state availability and transient packet loss rate, delay of the network in the case of fault. Analysis and simulation results show that this quantitative modeling and analysis are rational and useful evaluation approach to MANET survivability performance and the model could be applied in quantitative analysis of MANET survivability.
