Abstract. In the presence of interference, two single hop links can in-
teract in a number of different ways, exhibiting significantly different
behavior. In this paper, we consider the impact of these two-flow inter-
actions on multi-hop chains. Specifically, we characterize the different
types of interactions that arise in chains between hops that do not share
a common node. We develop closed formed expressions to estimate the
probability of occurrence of these interaction combinations. We use sim-
ulation to characterize the performance of the most common types of
chains. We make a number of interesting observations: (1) the most de-
structive types of two-flow interactions do not arise commonly in chains;
(2) the throughput of chains does not vary significantly with the types of
