    abstract = "Consider a dense wireless network of nodes, which can be used to
transfer data between arbitrary sources and destinations. In this paper
we develop a methodology based on variational calculus to optimize a
number of path metrics, such as the success probability or the total
power consumed by a packet delivery in the presence of external
interference. We then extend the approach to the case of multiple
origin-destination pairs, in which the relaying of each packet causes
interference to the other. In both cases, we show that the optimal path
may differ significantly from a straight line. We then discuss the
consequences of these deviations in the context of network design."
