Abstract

To reveal the effect of node misbehaviors and defense mechanisms against them on the node cooperation in anonymous routing protocol for MANET (Mobile Ad-hoc NETworks)

an anonymous node state transition model based on semi-Markov process is proposed on the features of anonymous node state transition.Under this model

according to the characteristics of large energy consumption and high demand for privacy protection of anonymous node

we give a theoretical estimation of the limiting probability of node states

and present a model of the node state transition probability matrix and transition time expectation matrix.An experimental analysis to the effect of different model parameters on the limiting probability of node states verifies the model’s validity at last.
