Double Cluster-Heads Routing Policy Based on the Weights of Energy-Efficient for Wireless Sensor Networks

It is important that balancing the node´s energy consumption effectively in wireless sensor network. We propose a novel double cluster-head routing policy based on clustering hierarchy routing. According to balancing the number of neighbor nodes, surplus energy and distance weights, we adopt first and second cluster-head mode. Cluster heads are responsible for data collection and transmission respectively. This mechanism could avoid high energy consumption in single cluster head and “false” death phenomenon. Simulation results show that based on the weights and a periodic cluster-head selection will increase the overall performance of the network, decrease the cluster head energy consumption, balance energy consumption between member nodes, and prolong the entire lifetime of network.
