A Serial MIS Based CDS Constructing Algorithm for Wireless Networks

Virtual backbone is helpful to reduce computation and communication overhead in wireless networks. Based upon serial Maximum Independent Set (MIS) constructing algorithms, this paper presents a weight and timing based triggering Connected Dominating Set (CDS) constructing algorithm. In the algorithm, the nodes orderly join the MIS one after another, thus it greatly reduces the number of edge nodes, and builds a CDS with certain upper-limit. The algorithm is also designed to reduce the communication complexity, and helps to reduce the node´s power consumptions.
