A Novel Path Stability Computation Model for Wireless Ad Hoc Networks

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.
