Clustering unbalancing will lead nodes’ energy depletion early

shorten network life in wireless sensor networks（ WSNs）.A multi-sector and multi-hop in ring clustering routing（ MMCR） algorithm is proposed.According to optimal cluster number clustering in each ring based on RBMC sub-loop model

cluster head is generated through multi-round rotation mechanism

and communication in cluster is realized through single hop

commuication between clusters is realized by combination of single hop and multi-hop.Simulation experiment show that the MMCR has better performance in network life cycle

energy utilization and data transmission efficiency than LEACH

E-LEACH

ERBMC in large-scale network.
