Abstract

We propose a silent self-stabilizing asynchronous distributed algorithm to find a 2-minimal dominating set (2-MDS) in networks of girth at least 7. Given a graph G=(V,E), a 2-MDS of G is a minimal dominating set DV such that D{pi,pj}{pz} is not a dominating set for any nodes pi,pjL(pipj) and pz /D. The girth is the length of the shortest cycles in the graph. We assume that the processes have unique identifiers. The proposed algorithm constructs a 2-MDS in the networks of girth at least 7 under the weakly fair distributed daemon. The time complexity is O(nH) rounds, and the space complexity is O(logn) bits per process, where n is the number of processes and H is the diameter of the network.
