Energy-Efficient Dynamic Dominating Set Construction in Wireless Sensor Networks

strategy is proposed to establish connection for all nodes so as to communicate in one hop to their cluster heads and consequently reducing the energy consumption. Topology control along with a clustering technique elects cluster heads to form a dominating set. The proposed hybrid approach constructs a dynamic dominating set based on energy and coverage metrics with low computational complexity and significant reduction in the amount of message overhead required for dominating set construction. Simulation results show that the set of elected cluster heads is a dominating set constructed dynamically on every round having optimal one-hop cluster.
