【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。
[Abstract]:Wireless sensor network (WSN) technology has become a trend and necessity to obtain and manage fine agricultural information. In view of the large area, long monitoring time and low power consumption of WSN in the field of large-scale farmland planting and monitoring, wireless sensor network technology has been applied to obtain and manage fine agricultural information. Based on the complex terrain and crop diversity, the load balancing protocol (ETLB-DEEC (Equilateral Triangle Load Balancing-DEEC) for the deployment of equilateral triangular nodes based on DEEC is studied, and the deployment mode of equilateral triangular nodes and the network partition are adopted. The concepts of "orphan node" and "shelter node" are put forward. On this basis, a multi-hop optimization mechanism for the shortest path cluster of base stations is designed to find multiple shortest path protocols. Simulation results show that the improved protocol can efficiently save the number of sensor nodes, achieve global network load balance, improve network energy utilization, and prolong the overall life cycle of WSN.
