Evaluation of link lifetime for the Random Waypoint mobility model

We propose an analytical expression to evaluate the distribution of link lifetimes in a mobile ad hoc network (MANET) under the Random Waypoint mobility model. We compare this model with a model found in the literature to derive residual link lifetimes. From the derived model, numerical results are evaluated and compared. We found that the residual link lifetime has link durations that last longer for the mobility in steady-state regime and can be used to appropriately devise new communication protocols for MANETs.
