Here, the authors account for the fact that MAC protocols incorporate a finite number of transmission attempts per packet. The performance of a path depends not only on the number of the links on the path and the quality of its links, but also on the relative positions of the links on the path based on this paper, they propose ETOP (Expected number of Transmissions On a Path), a path metric that captures the expected number of link layer transmissions required for reliable end-to-end packet delivery. They can analytically compute ETOP, which is not trivial, since ETOP is a non-commutative function of the link success probabilities.
