Research on energy optimization of wireless sensor networks based on MQAM modulation

Due to the special distribution of wireless sensor network nodes, the energy consumption of the nodes has strict requirements. In this paper, we propose an energy optimization scheme for wireless sensor networks based on modulation optimization. We analyze the relationship among energy consumption, modulation, the distance between nodes and modulation parameters. Finally, the simulation results show that the proposed method can optimize the transmission energy of 40% in single-carrier system.
