Abstract

The complexity of designing self-stabilizing systems is often compounded by the assumptions about the underlying schedulers. This paper presents a method to transform a self-stabilizing algorithm working under a given arbitrary, but potentially very restrictive, scheduler to a self-stabilizing algorithm under any weakly fair scheduler. The method presented here implements a progress monitor by exploiting the knowledge of a ranking function -used for proving convergence under the original scheduler- to carry out the transformation.
