摘要
无线传感器网络技术应用于精细农业信息获取与管理已成为一种趋势和必然,针对WSN在大规模农田种植监测领域中所面临的监测面积大、监测时间长、低功耗要求、地势复杂以及作物多样等问题,深入研究基于DEEC的等边三角形节点部署的负载均衡成簇协议ETLB-DEEC(Equilateral Triangle Load Balancing-DEEC),采用等边三角形网格节点部署方式与网络分区,提出"孤儿节点"和"收容节点"的概念。在此基础上,设计一种面向基站最短路径簇间多跳寻优机制,可找寻多条最短路径协议。仿真结果表明,改进的协议具备高效节省传感器节点数、实现全局网络负载均衡,提高网络能量利用率,延长WSN整体生命周期等功能和特点。
Nowadays,applying acquisition and management information of wireless sensor networks technology has become a inevitable trade of precision agriculture. For large-scale farmland planting monitoring area,challenges are the requirement of detecting large-scale,long time detection,complex terrain,lower power achievement and species diversity. This article is thoroughly talking about ETLB-DEEC which can solve the above problems by using＂Orphan Node＂and＂Asylum Node＂,and applying node deployment with equilateral triangle grid and network division tactics.Based on ETLB-DEEC,a base oration design of shortest path between each cluster multi-hop optimization mechanism has been discussed,which can find multiple shortest path. The simulation proved that ETLB-DEEC can effectively save the quantity of sensors and can realize load balance of the whole network,which also improve the usage efficiency of network power and extend the lifetime of the WSN.
