A distributed algorithm is presented for constructing a nearly optimal Steiner tree in an asynchronous network represented by a weighted communication graph G=(V, E, c). The worst-case cost ratio of the obtained solution to any given minimum-cost Steiner tree T min is 2 (1− 1 l), where l is the number of leaves of T min. The message complexity of the algorithm is O (| E|+| V|∗(| V|+ log| V|)) and the time complexity is O| V|*| V|), where S is the subset of nodes of G to be connected.
