Abstract: There will be great clusters and small clusters coexistence phenomena in clustering wireless sensor networks. It results in unbalanced energy consumption of the entire network, thus reducing network performance. By using cooperative transmission scheme based on adjacent great cluster and small cluster, it greatly balances the energy consumption of the network and improves the reliability of communication. The simulation results show that the cooperative transmission scheme based on adjacent great cluster and small cluster is an energy-efficient collaborative program and can well balance network energy consumption, and has superior performance in prolonging the network lifetime.
