| 摘 要： | 结合实际应用中传感器网络能量分布不均衡的特点,分析了以低功耗自适应集簇分层型协议(Low Energy Adaptive Clustering Hierachy Protocol,LEACH)为代表的分簇路由协议存在的不足。在改进LEACH协议的基础上,提出了LEACH-SCE协议,并以二级能量异构网络为例通过MATLAB软件对协议的性能进行了仿真验证,仿真结果表明,通过优化高能节点的簇头选择概率,改进协议可以更加有效地利用网络能量,同等条件下,比LEACH协议的生存周期提高了31%,有效节约了网络成本。

| Abstract: | Combining the characteristics of wireless sensor network that the distribution of the energy is unbalanced in actual application,the disadvantages of the clustering protocols as LEACH are analyzed.The protocol of LEACH-SCE is proposed by improving LEACH,which is validated by simulation in 2nd heterogeneous network.The simulation result shows that the improved protocol can utilize the network energy better by increasing the cluster head propability selection of high-energy nodes,the survival region is prolon... |
