We present an analytical framework and statistical models to accurately characterize the lifetime of a wireless link and multihop paths in mobile ad hoc networks (MANET).We show that the lifetimes of links and paths can be computed through a two-state Markov model and that the analytical solution follows closely the results obtained through discrete-event simulations for two mobility models, namely, random direction and random waypoint mobility models.We apply these models to study practical implications of link lifetime on routing protocols.We compute optimal packet lengths as a function of mobility, and show that significant throughput improvements can be attained by adapting information packet lengths to the mobility of nodes in a MANET.
