| 摘 要： | 无线传感器网络中簇头的频繁更换导致大量能量用于发送成簇信息，从而大幅度降低网络性能。为此，提出多轮成簇算法(MRCA)，通过改进轮模型减少簇头选举次数，利用辅助簇头分担主簇头的能量消耗，以均衡整个网络的能耗。仿真结果表明，与LEACH和HEED算法相比，MRCA能均衡网络能耗，延长网络生存周期。 |
| 关 键 词： | 成簇 能耗均衡 网络生存周期 多轮成簇算法 辅助簇头 |

| Abstract: | Multiple Rounds Clustering Algorithm(MRCA) is proposed for the problem of frequent-changing cluster head in wireless sensor network and most energy is used to send clusters information,through improvement wheel model to reduce the number of changing cluster head.Meanwhile,the assistant cluster head is used to share the energy consumption of main cluster head,for balancing the whole network energy consumption.Simulation results show that compared with LEACH and HEED,MRCA is improved in prolonging network life cycle and equilibrium network performance. |
| Keywords: | clustering energy consumption balance network life cycle Multiple Rounds Clustering Algorithm(MRCA) assistant cluster head |
