ABSTRACT

Route protocols are designed to have fault tolerance ability which impact the reliability of MANET strongly, hence the evaluation of MANET protocol fault tolerance ability is helpful to measure and improve the network reliability and performability. The traditional evaluation methods prefer evaluating the fault tolerance ability through performance evaluation process and measurement metrics, without considering the fault tolerance mechanism of route algorithm. Based on these problems, a new network model and a corresponding evaluation method are proposed from route protocol fault tolerance mechanism perspective. At last, the validity of the model and approach are verified through a MANET simulation case study, through the contrast experiments with NS-3 simulation based on specific cases, the model and method proposed in this paper shows satisfactory performance on accuracy and efficiency. Then the correlation between fault tolerance ability and performance is further analyzed, and the result should be meaningful to network and protocol designing.
