Memory Efficient Self-Stabilizing k-Independent Dominating Set Construction
Résumé
We propose a memory efficient self-stabilizing protocol building k-independent dominating sets. A k-independent dominating set is a k-independent set and a k-dominating set. A set of nodes, I, is k-independent if the distance between any pair of nodes in I is at least k+1. A set of nodes, D, is a k-dominating if every node is within distance k of a node of D. Our algorithm, named SID, is silent; it converges under the unfair distributed scheduler (the weakest scheduling assumption). The built k-independent dominating sets contains at most 2n/(k+2) nodes, n being the network size. The protocol SID is memory efficient : it requires only 2log((k+1)n+1)+1 bits per node. The correctness and the termination of the protocol SID is proven.
