Given n uniformly and independently points in the d dimensional cube of unit volume, it is well established that the length of the minimum spanning tree on these n points is asymptotic to /3MsT(d)n(d-l)/d,where the constant PMST(d) depends only on the dimension d. It has been a major open problem to determine the constant 3MST(d). In this paper we obtain an exact expression of the constant MST(d) as a series expansion. Truncating the expansion after a finite number of terms yields a sequence of lower bounds; the first 3 terms give a lower bound which is already very close to the empirically es

For example, the broadcasting in a network is sending a message from a given node to all other nodes in the network. We can design a fault-tolerant broadcasting scheme based on independent spanning trees [2] [8]. The fault-tolerance can be achieved by sending k copies of the message along k independent spanning trees rooted at the source node. If the source node is faultless, this scheme can tolerate up to k-1 faulty nodes. Two-dimension to
