大规模无线传感器网络环域多扇区多跳分簇路由算法

无线传感器网络(WSNs)中分簇不均衡会导致一些节点能量过早耗尽,网络生命周期缩短。提出一种环域多扇区多跳分簇路由(MMCR)算法。在RBMC分环模型上,各环域内根据最优分簇数分扇区即分簇,多轮旋转机制产生簇头,簇内单跳通信,簇间根据距离权值、单跳、多跳相结合通信。仿真实验表明:该算法与LEACH,E-LEACH,ERBMC相比,在较大规模网络中,网络生命周期、能量利用率和数据发送效率都具有较好的性能。

Multi-sector and multi-hop in ring clustering routing algorithm for large-scale WSNs

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.
