Summary :

In this paper we study a classical firing squad synchronization problem on a model of fault-tolerant cellular automata that have possibly some defective cells. Several fault-tolerant time-efficient synchronization algorithms are developed based on a simple freezing-thawing technique. It is shown that, under some constraints on the distribution of defective cells, any cellular array of length n with p defective cell segments can be synchronized in 2n - 2 + p steps.
