Abstract
The use of edge-disjoint spanning trees or independent spanning trees in a network for data broadcasting has the benefits of increased of bandwidth and fault-tolerance. In this paper, we propose an algorithm which constructs n edge-disjoint spanning trees in the n-dimensional twisted cube, denoted by TQ n . Because the n-dimensional twisted cube is n-regular, the result is optimal with respect to the number of edge-disjoint spanning trees constructed. Furthermore, we also show that n 2 of the n edge-disjoint spanning trees constructed are independent spanning trees. This algorithm runs in time O( N log N) and can be parallelized to run in time O(log N) where N is the number of nodes in TQ n .
