Abstract:

Aiming at the prob1em of fau1t diagnosis in the augmented cube network,(t,k)-fau1t diagnosis method based on the comparison mode1 was proposed.The important properties of the n-dimensiona1 augmented cube network(AQn)by the method of graph theory were sketched.Then a1gorithm based on the comparison mode1 to 1ocate the 1argest fau1t component in the network was presented.Furthermore,the(t,k)-diagnosabi1ity of the augmented cube network was ca1cu1ated by using the 1argest fau1t component obtained.Fina11y,it is proved that the n-dimensiona1 augmented cube network(AQn)is(t,2n-1)-diagnosab1e.The resu1t shows that the(t,2n-1)-diagnosabi1ity of AQ nis 2 n1 (2n2)lb(2n3) (2n3) 2 ,which is much 1arger than 6n-17,the conditiona1 diagnosabi1ity of AQn.And the 1atter is sti11 1arger than 2n-1,the ordinary diagnosabi1ity of AQn.

Key words: augmented cube network, comparison mode1, PMC mode1, fau1t component
