1. A method for tracking link mobility between two mobile nodes, comprising: estimating, at each mobile node, a link mobility state between a pair of mobile nodes; accumulating successively the link mobility states; estimating link mobility parameters using the successively accumulated link mobility states; predicting a link availability probability using the estimated link mobility parameters; and tracking continuously a link stability metric of nodes being on a path between the pair of mobile nodes after transmitting packets between the pair of mobile nodes using the predicted link availability probability, wherein the link mobility state is determined by a relative distance, a relative velocity, and a relative acceleration between the pair of mobile nodes.
