A Novel Energy-Efficient Dynamic Voting Cluster Algorithm for Wireless Sensor Networks

For monitoring burst events in reactive wireless sensor networks (WSNs),an novel energy-efficient dynamic voting cluster (EE-DVC) algorithm is proposed. EE-DVC has three obvious features: Firstly, it adopts virtual grid ideas to divide each cluster into MtimesN square area and select a working node in each grid to reduce redundant information and save energy. Secondly, cluster head is dynamic voted according residual energy among the working nodes in each grid. Last, it improves energy utility by changing the activity of wireless communication module of sensor nodes, energy model and state transition of sensor nodes. Simulation results show that, compared with UVDC and LEACH, EE-DVC significantly reduces in average energy consumption and prolong the network lifetime.
