Optimized LEACH Protocol Based on Data Volume-distance Distribution

Aiming at the unreasonable cluster head selection in the classical LEACH algorithm, which causes uneven energy consumption and short network life cycle in wireless sensor networks, this paper proposes a Leach Protocol optimization based on Multi-hop with Distribution by Data Volume- Distance (LEACH-MP) algorithm. During network initialization, cluster head selection is performed with full consideration of node residual energy; the generation of very large clusters and very small clusters is reduced by homogenizing the number of cluster members in the cluster splitting phase; the data fused with cluster heads is passed to the base station in data transmission. Simulation experiments prove that the LEACH-MP algorithm can effectively extend the operation cycle of the sensor network and reduce the excessive consumption of node energy.
