In ad hoc networks, stability is the priority factor in route selection. However, the traditional path stability computation methods are so idealized that their results do not accord with the reality. A novel path stability computation model is proposed in this letter, in which the correlation factor is introduced to describe the dependency degree between arbitrary adjacent links. Based on a series of correlation factors, a simple and universal expression for computing the stability probability of a path is derived. Simulation results show that our model, which can obtain more accurate results and select more stable routes, outperforms the traditional methods.
