Abstract

The verification of the self-stabilization property of a distributed algorithm is a complicated task. By exploiting certain analogies between self-stabilizing distributed algorithms and globally asymptotically stable feedback systems, techniques originally developed for the verification of feedback system stability can be adopted for the verification of self-stabilization of distributed algorithms. In this paper, we show how for a certain subclass of dynamic systems – namely piecewise affine hybrid systems – and distributed algorithms suitable to be modeled in terms of these dynamic systems, a proof of convergence can be obtain fully automatically. Together with some additional non-automated arguments, the complete proof of self-stabilization can be derived.
