| 摘 要： | 针对LEACH协议能耗不均和节点过早死亡的缺陷,提出了能耗均衡的自组织多跳聚类协议。该协议通过在竞争簇首过程中加入能量参量来均衡节点能耗,并完全采用节点自组织的方式构建簇首间的多跳网络,减小了协议开销、避免了外围节点的早死,比传统聚类协议更能适应大规模的传感器网络。仿真实验证明,与已有聚类协议相比,自组织多跳聚类协议能够均衡网络负载,延长网络寿命。

| Abstract: | The LEACH protocol for wireless sensor network has some limitations.For example,energy-consuming among nodes is not balanced,and the distribution of cluster heads is not even.Based on the analysis of LEACH,a self-organized load-balanced multi-hop protocol is proposed.With the method of adding energy parameter,nodes with more energy have more probability to be cluster heads.By distributing cluster heads more evenly,energy-consuming among nodes is balanced.Finally,those cluster heads construct a multi-hop network on themselves.Simulation results demonstrate that the new mechanism is effective in balancing the energy-consuming among nodes and thus prolonging the lifetime of network. |
