Faulty Diagnosis Phase definition
Faulty Diagnosis Phase. Let h (1≤h≤n) be a fault-free processor. h can detect processor k (1≤k≤n) as faulty if: F1: h receives the λ from k (or no message is received from k) and the number of copies of k is greater than (n-1- fd)/3, then processor Pk as dormant faulty processor; F2: For each Ti If val(αk) ≠ majority value maj(α), then *fk = *fk + 1 Next If *fk > (n-1- fd )/3, then processor Pk as arbitrary processor; F3: If fk < (n-1- fd)/3 and fa< (n-1- fd)/3, then For each Ti For 1 to k *fα = *fα + 1 Next Next If *fα > (n-1- fd)/3, then processor Pα as arbitrary faulty processor; F : Compute the T k−1 by taking the majority on each T k (i ⊄ f ) 4 i i a If val( T k−1 ) ≠ val( T k−1 ) (i ≠ j) and f < (n-1- f )/3, then the source s as arbitrary faulty processor.
