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 , a 2-MDS of is a minimal dominating set such that is not a dominating set for any nodes and . 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 rounds, and the space complexity is bits per process, where is the number of processes and is the diameter of the network.
