On reliability of the folded hypercubes q

چکیده
In this paper, we explore the 2-extra connectivity and 2-extra-edge-connectivity of the folded hypercube FQn. We show that j2(FQn) = 3n 2 for n P 8; and k2(FQn) = 3n 1 for n P 5. That is, for n P 8 (resp. n P 5), at least 3n 2 vertices (resp. 3n 1 edges) of FQn are removed to get a disconnected graph that contains no isolated vertices (resp. edges). When the folded hypercube is used to model the topological structure of a large-scale parallel processing system, these results can provide more accurate measurements for reliability and fault tolerance of the system. 2006 Elsevier Inc.

The g-Extra Conditional Diagnosability of Folded Hypercubes
Diagnosability plays a crucial role in measuring the reliability and fault tolerance of interconnection networks. The g-extra conditional diagnosability of multiprocessor systems is a new diagnosability, which is more accurate than the classical diagnosability. In this paper, we show that the g-extra conditional diagnosability t̃g(FQn) of the folded hypercube FQn is (g + 1)n − ( g 2 ) + 1 under ...
متن کاملCharacterizing which powers of hypercubes and folded hypercubes are divisor graphs
In this paper, we show that Q n is a divisor graph, for n = 2, 3. For n ≥ 4, we show that Q n is a divisor graph iff k ≥ n− 1. For folded-hypercube, we get FQn is a divisor graph when n is odd. But, if n ≥ 4 is even integer, then FQn is not a divisor graph. For n ≥ 5, we show that (FQn) k is not a divisor graph, where 2 ≤ k ≤ ⌈ 2 ⌉ − 1.
متن کاملEmbedding Variants of Hypercubes with Dilation
Graph embedding has been known as a powerful tool for implementation of parallel algorithms and simulation of interconnection networks. In this paper, we introduce a technique to obtain a lower bound for the dilation of an embedding. Moreover, we give algorithms for embedding variants of hypercubes with dilation 2 proving that the lower bound obtained is sharp. Further, we compute the exact wir...
