摘要
提高网络整体性能与节能,将加权因子引入到LEACH协议改进方法中,根据每个节点的剩余能量、网络平均剩余能量、节点与网络在前一轮中所消耗的平均能量来确定最优簇头。综合考虑数据信息传输与接收的能耗、簇头节点的能耗以及传输ADV的能耗优化簇头节点数量。采用Matlab进行仿真对比研究,结果表明,与其它几种协议相比,本协议更能够显著降低节点能耗,网络中的簇头节点达到均匀分布状态,且其生命周期更长。
To improve the properties of network as a is introduced to the LEACH protocol to optimize the node, average residual energy of the network and optimized numbers of nodes are determined accor transmission, energy consumption of cluster h whole and save the energy, the weighting factor cluster head based on the residual energy of every the average consumption of former circle. The ding to the energy consumed during the data cad nodes and ADV transformation energy consumption. Matlab simulation results demonstrate that there are such features such as low energy consumption, even node distribution and long-life span in the improved protocol, compared with other protocols.
