Fibonacci cubes-a new interconnection Topology

A novel interconnection topology called the Fibonacci cube is shown to possess attractive recurrent structures in spite of its asymmetric and relatively sparse interconnections. Since it can be embedded as a subgraph in the Boolean cube (hypercube) and it is also a supergraph of other structures, the Fibonacci cube may find applications in fault-tolerant computing. For a graph with N nodes, the diameter, the edge connectivity, and the node connectivity of the Fibonacci cube are in the logarithmic order of N. It is also shown that common system communication primitives can be implemented efficiently.>
