摘要
基于经典LEACH协议,针对簇内通信方式进行了改进,在中转链路建立中,采用数据融合技术,进一步降低簇内通信能量消耗,减少簇首负荷;将动态成簇与静态成簇协同作用,从总能量消耗最低与全局能量均衡两个方面进行了改进。采用OMNet++进行仿真,表明改进后的算法减小了簇内数据传输总距离,降低了总能量消耗,延长了网络寿命。
Based on classical LEACH, it improved the communication in clusters by building relay links and applying data fusion technology. This further reduced the energy consumption of communi- cation within the cluster and reduced the load of cluster heads. By the synergy of the dynamic and static clustering, it achieved a balance between the two targets of the lowest energy consumption and global energy balance . The simulation shows that the proposed algorithm optimizes the average transmission distance, thus saving the network energy consumption, prolonging the life span of the entire network.
