| 摘 要： | LEACH协议是无线传感器网络中被广泛应用的聚类协议,但它存在负载不均衡的缺陷.通过分析LEACH协议聚类中节点的能耗情况,建立节点的能耗模型,找出了聚类之间以及节点之间负载不均衡的原因.基于原有协议,提出了一种新的LB-LEACH通信协议.使用OMNET 进行仿真实验,实验结果表明,新协议能够使聚类间的负载更加均衡,减少节点的过早死亡,延长整个网络的寿命.

| Abstract: | The protocol of LEACH (low-energy adaptive clustering hierarchy) is widely used in wireless sensor network. But it has the disadvantage of unbalanced load. By analyzing the energy-consuming of nodes in clusters for LEACH, the energy-consuming model is established and the reason is found why load among clusters is not balanced. Based on LEACH, a new load-balanced LEACH com- munication protocol is proposed. Simulation results demonstrate that our proposed approach is effective to balanc the energy-consuming among clusters and prolong the network lifetime. |
