Abstract

Finding a maximal or maximum matching in a graph is a well-understood problem for which efficient sequential algorithms exist. Applications of matchings in distributed settings make it desirable to find self-stabilizing asynchronous distributed solutions to these problems. We first present a self-stabilizing algorithm for finding a maximal matching in a general anonymous network under read/write atomicity with linear round complexity. This is followed by a self-stabilizing algorithm, with quadratic time complexity, for finding a maximum matching in a bipartite network under composite atomicity. These results represent significant progress in the area of distributed algorithms for matchings.
