摘要
本文首先介绍了基于WSN的风力发电运行监测系统的结构,针对风电场的特殊模型,提出了使用LEACH协议作为其路由协议的方案。针对LEACH协议中簇头节点能量消耗过大和簇头节点与基站通信距离长的特点,提出以节点剩余能量来作为簇头节点选取的标准,同时通过限制簇内节点数目,在传输中提出簇内单跳、簇间多跳的路由方式,以减少簇头能量消耗,从而延长网络生存时间。最后使用MATLAB对LEACH及改进后的协议作仿真分析,验证了改进的有效性。
This article introduces the WSN-based monitoring system for wind power generation,then proposes make use of LEACH agreement for special model of wind power field.For the shorting that the large energy consumption of cluster head and the long-distance from cluster head node to the base station,put forward residual energy of nodes as the cluster head node selection criteria,and by limiting the number of nodes in the cluster, using a routing mode that single hop in the cluster and multi-hop between each cluster,to reduce the energy consumption of cluster head,thus extends the network lifetime.Finally,using MATLAB on LEACH and improved protocol for the simulation to verify the effectiveness of the improvement.
