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 the classical LEACH protocol, this paper improves the communication mode in the cluster. In the establishment of the transit link, the data fusion technology is adopted to further reduce the communication energy consumption in the cluster and reduce the load on the cluster head. By combining the dynamic clustering with the static clustering, The improvement is made from two aspects: the lowest total energy consumption and the global energy balance. The simulation using OMNet ++ shows that the improved algorithm reduces the total distance of data transmission in the cluster, reduces the total energy consumption and prolongs the network lifetime.
