We present a new distributed approximation algorithm that constructs a minimum connected dominating set (MCDS) for wireless ad hoc networks based on a maximal independent set (MIS). Our algorithm, which is fully localized, has a constant approximation ratio, and O(n) time and O(n) message complexity. In this algorithm, each node only requires the knowledge of its one-hop neighbors and there is only one shortest path connecting two dominators that are at most three hops away.
