Incrementally extensible folded hypercube graphs

Abstract

In this paper,ce propose the incrementally extensible folded hypercube (IEFH) graph as a new class of interconnection networks. for arbitrary number of nodes. We show this system is optimal fault tolerant and almost regular (i.e., the difference between the maximum and the minimum degree of nodes is at most one). The diameter of this topology is half of that of the incomplete hypercube (IH), the supercube, or the IEH graph. also devise a simple routing algorithm for the IEFH graph. Further we embed cycles and complete binary, trees into this graph optimally.
