An Efficient Algorithm for Finding an Almost Connected Dominating Set of Small Size on Wireless Ad Hoc Networks

In this paper, we propose an efficient, distributed and localized algorithm for finding an almost connected dominating set of small size on wireless ad hoc networks. Broadcasting and routing based on a connected dominating set (CDS) is a promising approach. A set is dominating if all the nodes of the network are either in the set or neighbors of nodes in the set. The efficiency of dominating-set-based broadcasting or routing mainly depends on the overhead in constructing the dominating set and the size of the dominating set. Our algorithm can find a CDS faster and the size of the found CDS is smaller than the previous algorithms proposed in the literature. Although our algorithm cannot guarantee the set found is actually a CDS but from our simulation results, the probabilities that the found set is a CDS are higher than 99.96% in all cases
